Are currents caused by temperature?
Currents may also be caused by density differences in water masses due to temperature (thermo) and salinity (haline) variations via a process known as thermohaline circulation. These currents move water masses through the deep ocean—taking nutrients, oxygen, and heat with them.
Why are currents different temperatures?
Differences in water density, resulting from the variability of water temperature (thermo) and salinity (haline), also cause ocean currents. This process is known as thermohaline circulation. In cold regions, such as the North Atlantic Ocean, ocean water loses heat to the atmosphere and becomes cold and dense.
Do warm currents increase temperature?
Horizontal currents moving northward or southward may carry warmed or cooled water for very long distance. The displaced warm water raises the temperature of the air while the cold water cools the air, and the land surface where the blows.
Do currents affect the climate on Earth?
Ocean currents act much like a conveyor belt, transporting warm water and precipitation from the equator toward the poles and cold water from the poles back to the tropics. Thus, ocean currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth’s surface.
What currents are warm?
Name of Current | Nature of Current |
---|---|
North Equatorial Current | Hot or Warm |
Kuroshio Current | Warm |
North Pacific Current | Warm |
Alaskan Current | Warm |
Why are some currents warm and others cold?
The cold currents often form when the air on the subtropical high blows over a cold mass of water, then the cold air is dragged to the equator. Warm currents, on the other hand, are large masses of warm water moving further away from the equator, at higher temperatures.
How do currents affect climate?
Ocean currents act much like a conveyer belt, transporting warm water and precipitation from the equator toward the poles and cold water from the poles back to the tropics. Thus, currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth’s surface.
What is the difference between warm and cold currents?
Temperature difference: Warm water is lighter and rises but the cold water is denser and sinks. This makes the difference in the levels of a sea. Warm equatorial water moves polewards along the surface while the cold water from the poles move along the bottom towards the equator.
Why is the Benguela Current cold?
While the Benguela Current is cold, generated by water from the very deepest parts of the ocean moving in line with the rotation of the Earth, the Southern Equatorial Current is warm.
What are surface currents?
A current is a stream of moving water that flows through the ocean. Surface currents are caused mainly by winds but not daily winds. Surface currents are caused by the major wind belts. These winds blow in the same direction all the time. So they can keep water moving in the same direction.
Does elevation seem to impact average temperatures?
As you increase in elevation, there is less air above you thus the pressure decreases. As the pressure decreases, air molecules spread out further (i.e. air expands), and the temperature decreases.
What is the relationship between altitude and temperature of a place?
Near the Earth’s surface, air gets cooler the higher you climb. As you climb a mountain, you can expect the air temperature to decrease by 6.5 degrees C for every 1000 meters you gain. This is called the standard (average) lapse rate.
How do ocean currents affect temperature check all that apply?
Check all that apply. Ocean currents can carry warm water, which can raise the temperature of the air and land. Ocean currents can carry cold water, which can cool the air and land.
What was temperature at its highest and at its lowest?
The highest temperature ever recorded on Earth was 136 Fahrenheit (58 Celsius) in the Libyan desert. The coldest temperature ever measured was -126 Fahrenheit (-88 Celsius) at Vostok Station in Antarctica.
How does the temperature and moisture level affect the weather in an area?
The more water evaporates and the more water vapor in the atmosphere in a given area, the higher the percentage of humidity in that area will be. That means hot places tend to have higher levels of humidity in the air than cool places since heat makes water evaporate faster.
Why do cold currents create deserts?
Cold currents form deserts by cooling the air above them.
By doing this, they reduce the capacity of the air to hold humidity, and this results in the…
What are cold currents?
Think of cold currents as currents moving toward the Equator. These waters are colder than the water they are moving into. If you were swimming in the ocean whose temperature was 70 degrees F and you swam into a current whose temperature was 60 degrees F, the sensation would be cold.
How does temperature affect ocean currents?
Warming temperatures result in weakened currents. If the water at the poles is not as cold and dense, it simply won’t be able to circulate as well. Additionally, the melting of the Greenland continental ice sheet is pouring freshwater into the salty ocean, again altering the density of the water masses.
What happens when warm and cold currents meet?
This is because air above the warm currents is warm which contains water vapour. When this warm current meet the cold current, the air above the cold current, causes the water vapour of the warm current to condense into tiny particles which form fog.

Why are these currents called cold currents?
Around the world, there are some similarities in the currents. For example, along the west coasts of the continents, the currents flow toward the equator in both hemispheres. These are called cold currents as they bring cool water from the polar regions into the tropical regions.
What currents are influenced by the Coriolis effect?
Because the Earth rotates on its axis, circulating air is deflected toward the right in the Northern Hemisphere and toward the left in the Southern Hemisphere. This deflection is called the Coriolis effect. Click the image for a larger view. Coastal currents are affected by local winds.
Is Benguela Current warm?
The Benguela Current is a cold, wide current that flows northwards along the west coast of southern Africa.
What is the temperature of the Benguela Current?
Surface temperatures average about 50 to 59 degrees F (10 to 15 degrees C) near the coast and reach up to 77 degrees F (25 degrees C) on the surface, out along the continental shelf.
Why are these current warm?
Because it is fed from lower latitudes, the Agulhas Current is warm, ranging in temperature from 57 to 79 °F (14 to 26 °C) at the surface. The average temperature is lower in southern sections near Antarctica.
What do surface currents affect?
Currents affect the Earth’s climate by driving warm water from the Equator and cold water from the poles around the Earth.
How does Earth’s orbit affect the weather and climate quizlet?
— As the Earth takes a more circular orbit than normal around the Sun, it stays consistently farther away from the Sun thus reducing the amount of solar radiation the Earth receives. This path would produce much cooler climates than average.
What factors affect the climate?
- Elevation or Altitude effect climate. Normally, climatic conditions become colder as altitude increases. …
- Prevailing global wind patterns. …
- Topography. …
- Effects of Geography. …

- Climate change over time.
How does air circulation affect climate?
The combination of oceanic and atmospheric circulation drives global climate by redistributing heat and moisture. Areas located near the tropics remain warm and relatively wet throughout the year. In temperate regions, variation in solar input drives seasonal changes.
What are the causes of currents?
i. Prevailing winds: Prevailing winds influence the ocean currents more than any other single factor. These winds blow in a particular direction and drag the surface water due to the force of friction. This leads to the formation of ocean currents.
How do surface currents move heat?
Surface currents move a lot of heat since most of the heat from solar radiation is absorbed on the water’s surface where the currents take place. When water is heated, it creates convection currents, resulting in an upwelling effect; thus, they distribute instead of storing the solar radiation.
Why does temperature drop with elevation?
The basic answer is that the farther away you get from the earth, the thinner the atmosphere gets. The total heat content of a system is directly related to the amount of matter present, so it is cooler at higher elevations.
Why higher elevation is colder?
High-altitude locations are usually much colder than areas closer to sea level. This is due to the low air pressure. Air expands as it rises, and the fewer gas molecules—including nitrogen, oxygen, and carbon dioxide—have fewer chances to bump into each other.
How many degrees is 1000 feet colder?
Estimating Temperature
On a dry, sunny day, the temperature typically drops 5.4-degrees Fahrenheit for every 1,000 feet in elevation gain, according to the National Weather Service. If it’s raining or snowing, that rate of change decreases to a 3.3-degree drop every 1,000 feet.
How does temperature affect the climate of an area?
Warmer temperatures can also lead to a chain reaction of other changes around the world. That’s because increasing air temperature also affects the oceans, weather patterns, snow and ice, and plants and animals. The warmer it gets, the more severe the impacts on people and the environment will be.
Which city has the highest temperature?
Currently, the highest officially registered temperature is 56.7C (134F), recorded in California’s Death Valley back in 1913.
What factor do you think is the cause of low temperature?
The most common causes of hypothermia are exposure to cold-weather conditions or cold water. But prolonged exposure to any environment colder than your body can lead to hypothermia if you aren’t dressed appropriately or can’t control the conditions.

What was the hottest temperature on Earth?
The current official highest registered air temperature on Earth is 56.7 °C (134.1 °F), recorded on 10 July 1913 at Furnace Creek Ranch, in Death Valley in the United States.
What’s the hottest temperature ever recorded on Earth?
With the Libya record abandoned, the official world record was given to a 134 degrees Fahrenheit (56.7°C) measurement taken at Death Valley on July 10, 1913.
Does temperature affect humidity?
Thus, temperature is also highly related to humidity. As the temperature rises, the amount of moisture that can be included in the air also increases. Therefore, the relative humidity changes even if the absolute humidity is the same.
Does humidity rise with temperature?
As noted by the Sciencing.com website, “As air temperature increases, air can hold more water molecules, and its relative humidity decreases. When temperatures drop, relative humidity increases.”
How does air pressure affect the weather?
Atmospheric pressure is an indicator of weather. When a low-pressure system moves into an area, it usually leads to cloudiness, wind, and precipitation. High-pressure systems usually lead to fair, calm weather.
How do warm currents affect climate?
Ocean currents act much like a conveyor belt, transporting warm water and precipitation from the equator toward the poles and cold water from the poles back to the tropics. Thus, ocean currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth’s surface.
How does a cold current affect weather?
Warm and cold ocean currents can affect the climate of coastal regions, but only when local winds blow in from the sea. Warm currents heat the air over the ocean and bring higher temperatures over land. Cold currents can lower air temperatures and can bring colder temperatures over land.
How hot is the ocean?
The average temperature of the sea surface is about 20° C (68° F), but it ranges from more than 30° C (86° F) in warm tropical regions to less than 0°C at high latitudes. In most of the ocean, the water becomes colder with increasing depth.

What is the difference between cold current and warm current?
Warm current flows from Equator to poles whereas cold currents originate in the polar region and flow towards the Equator. Warm currents move from the equator to the poles ex Gulf Stream, South Atlantic Current and Cold currents move from poles to the equator ex Labrador Current, West Australian Current.
What is the difference between warm surface currents and cold surface currents?
The global conveyor belt’s circulation is the result of two simultaneous processes: warm surface currents carrying less dense water away from the Equator toward the poles, and cold deep ocean currents carrying denser water away from the poles toward the Equator.
What happens when warm and cold currents meet shaala?
The meeting of cold and warm currents results into a meeting of the overlying warm air and cold air. The warm air meeting the colder air will cool the warm air below its dew point resulting in the formation of a thick fog.
Why are some currents warm and others cold?
