Does warm air sink at the equator?
In review, on a non-rotating earth, warm air would rise at the equator, go to the poles, sink to the surface, and flow back to the equator. But because the earth rotates, air is deflected from this path. Air rising at the equator only gets about 30° N and sinks back down to the earth, making the Hadley cell.
What happens to air when it is heated at the equator quizlet?
Wind causes air to move because of the differences in air pressure. The uneven heating of the Earth causes differences in air pressure. At the equator, warm air, which is less dense, rises, causing a low pressure. This is because the equator receives more direct solar energy than any other latitudes.
What is created when warm air rises at the equator and cold air sinks at the poles?
Air rises at the equator and sinks at the poles, creating a single convection cell in each hemisphere. The prevailing winds moving over the Earth’s surface blow from the poles towards the equator in both hemispheres (Modified by PW from globe image by Location_of_Cape_Verde_in_the_globe.
When warm air is heated by the sun and rises at the equator?
In the tropics, near the equator, warm air rises. When it gets about 10-15 km (6-9 miles) above the Earth surface it starts to flow away from the equator and towards the poles. Air that rose just north of the equator flows north. Air that rose just south of the equator flows south.
What happens to surrounding air as warm air rises?
As air warms up, the molecules start to vibrate and bump into each other, increasing the space around each molecule. Because each molecule uses more space for motion, the air expands and becomes less dense (lighter).
How does the air at the equator move?
In the tropics, near the equator, warm air rises. When the air cools, it drops back to the ground, flows back towards the Equator, and warm again. The, now, warmed air rises again, and the pattern repeats. This pattern, known as convection, happens on a global scale.
When does warm air rise near the equator?
In the tropics, near the equator, warm air rises. When it gets about 10-15 km (6-9 miles) above the Earth surface it starts to flow away from the equator and towards the poles. Air that rose just north of the equator flows north.
What happens to the air as it cools?
When the air cools, it drops back to the ground, flows back towards the Equator, and warm again. The, now, warmed air rises again, and the pattern repeats.
How is heat transferred from the equator around the world?
Heat from the equator is transferred around the globe in three cells that connect with each other, known as the tri-circular model. This creates a global pattern of atmospheric pressure and winds. The movement of air across the planet occurs in a specific pattern.
How does the movement of air across the Earth occur?
The movement of air across the planet occurs in a specific pattern. The whole system is driven by the equator, which is the hottest part of the Earth. Air rises at the equator, leading to low pressure and rainfall. When the air reaches the edge of the atmosphere, it cannot go any further and so it travels to the north and south.
