L 3.3: Wind

Air leaving the equator cools, becomes more dense, and sinks forming a pattern of smaller ____________________ cells.

At what latitudes are low pressure belts located?

Air leaving the poles warms, becomes less dense, and rises forming smaller convection cells and creating areas of ____________ pressure.

Air leaving the equator cools, becomes more dense, and sinks forming a pattern of smaller convection cells. This forms areas of ________________ pressure.

T / F: The sun heats the atmosphere unevenly and creates differences in temperature above Earth’s surface.

The jet stream causes the deflection of moving objects from a straight path, which is caused by the Earth revolving around the sun.

Winds and surface currents are caused by the sun.

Zone of weak, variable winds, calm areas; located at 30° N and 30°S

Winds that blow between 30° latitude and the equator in both hemispheres

Winds that blow between the poles and 60° latitude in both hemispheres

Winds that blow between the 30° and 60° latitude in both hemispheres

Very little wind due to warm, less dense air and low pressure; calm area at equator

Narrow belts of high speed winds that blow from west to east; subtropical and polar

Winds that blow from any direction over short distances

Winds are caused by the uneven heating of the earth due to varying specific heats.
