what causes the global convection current between the equator and the poles?, check these out | What causes the global convection currents between the equator and the poles Brainly?

What causes convection currents at poles? Radiant heating from the Sun warms the surface of the Earth. … In addition, the Earth’s rotation moves warm water from the equator toward the poles, resulting in ocean currents that move heat from the equator to the poles and pushes cold water from the poles toward the equator.

What causes the global convection currents between the equator and the poles Brainly?

Answer: Because the Earth is (roughly) spherical the Sun’s light is distributed over a wider area towards the poles, so has less heating effect. Explanation: This effect causes the equatorial regions to be heated considerably more, in turn heating the air masses above them which rise accordingly.

What is the main cause of global convection currents?

What is the main cause of global convection currents? Energy from the sun is transferred from the Earths surface to the atmosphere, resulting in atmospheric convection currents that produce winds. The “L” represents an area of low atmospheric pressure on the Earth’s surface..

Is there convection at the equator?

Earth’s heat distribution.

Convection cells move warm air from the equator towards the poles and cold air from the poles towards the equator. The result is that average temperatures found around the globe are more moderate than they would otherwise be.

How do convection currents work?

Convection currents form because a heated fluid expands, becoming less dense. The less-dense heated fluid rises away from the heat source. As it rises, it pulls cooler fluid down to replace it. … For instance, a hot radiator heats the air immediately around it.

What causes areas closer to the equator?

The sun’s rays strike Earth’s surface most directly at the equator. This focuses the rays on a small area. Because the rays hit more directly, the area is heated more.

What causes areas closer to the equator to have warmer air than areas farther away?

Areas closer to the equator have warmer air than areas farther away because the sun’s rays strike Earth’s surface at a greater angle near the equator.

What causes 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.

Why does hot air create convection currents?

Warm air is less dense and rises while cool air is denser and sinks. When the molecules are heated, they move faster and move apart, causing them to be less dense and rise. Source: Cool and heated gas, NOAA. When the warm air rises and the cool air sinks, convection currents are created.

How does convection affect ocean currents?

Thermal energy also moves within the ocean and within the atmosphere through the process of convection. During convection, cooler water or air sinks, and warmer water or air rises. This movement causes currents. These currents move water all around the earth, bringing warm water to cooler areas and vice versa.

What causes Hadley convection cells to form?

As the air leaves the equator, it rains away more moisture, becoming denser and slightly cooler, until finally dry, it sinks, creating the arid bands where many of the world’s famous deserts lie. This giant atmospheric conveyor belt, officially called a Hadley cell, brings us both tropical rain forests and deserts.

Why do convection areas occur near the poles?

At the poles the air is cold and the cold air wants to sink and as that cold polar air sinks it heads toward the equator and it bumps into this air heading toward the pole here and toward the South Pole here and it creates an area of rising air and again rising air produces high precipitation belts at about 60 degrees

What causes convection cells to form?

In the field of fluid dynamics, a convection cell is the phenomenon that occurs when density differences exist within a body of liquid or gas. These density differences result in rising and/or falling currents, which are the key characteristics of a convection cell.

How does convection heat the atmosphere?

Convection. Convection is the transfer of heat energy in a fluid. … As the rock’s temperature rises due to conduction, heat energy is released into the atmosphere, forming a bubble of air which is warmer than the surrounding air. This bubble of air rises into the atmosphere.

Which best explains how convection affects the atmosphere?

Convection in the atmosphere causes a change in air density, resulting in winds. Which statement best describes how energy transfer within Earth’s atmosphere can affect a weather condition? During radiation, waves transfer heat and light energy which affects the air temperature.

How does distance from the equator influence the climate of a place?

The distance from the equator affects the climate of a place. At the poles, energy from the sun reaches the Earth’s surface at lower angles and passes through a thicker layer of atmosphere than at the equator. This means the climate is cooler further from the Equator.

What causes ocean water near the equator to be warmer than ocean water farther north?

This means that at the equator, one beam of sunlight is concentrated on a small area, whereas at the north pole, one beam covers a much larger area. The equator therefore receives much more intense sunlight than the north/south poles, making the water at the equator warmer.

What happens when distance from the equator increases?

What happens when distance from the equator increases? Latitude: Temperature range increases with distance from the equator. Also, temperatures decrease as you move away from the equator. This is because the suns rays are dispersed over a larger area of land as you move away from the equator. …
