Front 1

lines run from east-to-west/w-t-e but they measure north or south of the equator (0° to 90°) splitting the earth into the Northern & southern hemisphere

atmosphere

Front 7

patterns of wind that happen over the world, they're created by the spin of the earth and the difference in temperatures

Back 7

Global Winds

Front 8

These winds predict most our weather, blows from west-to-east accross the United States

Back 8

prevailing westerlies

Front 9

This winds blow close to the north and southpoles, blows away from the poles and curve east to west

Back 9

Polar esterlies

Front 10

this wind are winds that circle near the equator (helps ship contains how which directuon they are going to)

Back 10

Trade winds

Front 11

air above the land heats up and rise and the cool air from water moves toward the land to replace the rising warm air.

Back 11

Sea breeze

Front 12

when the cool air replaced the rising warm air in the ocean

Back 12

Land Breeze

Front 13

warm air rises and moves up to the mountain

Back 13

valley breeze

Front 14

when the cool air sinks down that causing thr wind to move in the opposite direction

which way does the earth spin

Back 26

w.e. spin / west-to-east spin

Front 27

why does the earth's season change

Back 27

because the planet is slightly tilted on its axis as it travels around the sun

Front 28

start of spring : equal length of day & night

Front 32

sun is higher in the sky, the sunlight reaching the surface is more concentrated

Back 32

during summer

Front 33

the sun is lower in the sky

Back 33

during winter

Front 34

sunlight is spread out over a larger area
