The horizontal movement of air from and area of high pressure to an area of low pressure is called ____________.

• wind

• climate

• high pressure

• air pressure

Most differences in air pressure are caused by _______________ heating of the atmosphere.

• some

• equal

• unequal

• great

Warm air __________.

• is not part of the atmosphere

• has less energy

• sinks

• rises

Cool air has __________ pressure.

• low

• high

• medium

• unknown

Winds that blow over long distances in predictable patterns are called ____________.

• seasonal winds

• strong winds

• global winds

• local winds

Temperature differences between the equator and the poles produce giant __________________ in the atmosphere.

• clouds

• global warming

• Greenhouse Effect

• convection currents

What causes wind to blow?

• Differences in longitude 
• Shock waves from clouds 
• Differences in air temperature and pressure 
• The rotation of the earth

What is the Coriolis Effect and how does it effect global winds?

• Curving of winds due to rotation of earth curves wind counterclockwise in Northern Hemisphere and clockwise in the Southern Hemisphere
• Movement of ocean currents caused by earth rotation' counterclockwise in Northern Hemisphere and clockwise in Southern Hemisphere
• curve of global winds caused by global rotation clockwise in Northern Hemisphere and counterclockwise in Southern Hemisphere

A belt of calms or light variable winds and subsiding air located near the center of the subtropical high. Legend states when water supplies ran low for sailors, animals were the first to be rationed water. Dying from thirst or tossed overboard, these animals were sacrificed to conserve water for the men. They were then thrown overboard.

• doldrum latitudes

• trade wind latitudes

• horse latitudes

• pig latitudes

Two belts of winds that blow almost constantly from easterly directions and are located on the equator toward sides of the subtropical highs.

• Doldrums
• Trade winds
• Polar jet stream
• Westerlies
