Wind Flashcards

Front

What causes wind?

Back

The movement of air caused by differences in air pressure.

Front

How does wind happen?

Back

Wind happens due to the unequal heating of Earth's surface, where warm air rises creating low pressure and cold air sinks creating high pressure.

Front

Why do areas near the equator receive more sunlight?

Back

Sunlight strikes at a high angle year-round near the equator.

Front

Why do areas near the poles receive less energy from the sun?

Back

Sunlight strikes at a low angle near the poles, resulting in low energy.

Front

What happens to warm air?

Back

Warm air is less dense, so it rises, creating low pressure.

Front

What happens to cold air?

Back

Cold air is more dense, so it sinks, creating high pressure.

Front

In which direction does air move?

Back

Air always moves from high pressure to low pressure.

Front

What are global winds?

Back

Wind systems that occur at or near Earth's surface.

Front

What is the Jet Stream?

Back

Narrow belts of high-speed winds that blow from west to east between 7 km and 16 km above Earth's surface.

Front

What is the Coriolis Effect?

Back

The apparent curving of the path of a moving object from an otherwise straight path due to Earth's rotation.
