• water temperature differences

• volcanic island eruptions

• magnetic field of the Earth

In the Northern Hemisphere, winds traveling north appear to curve to the east because of

• Coriolis Effect

• convection currents

• polar easterlies

• trade winds

What causes convection currents in Earth’s atmosphere?

• heat from Earth’s core heats the land only at the equator

• glaciers moving away from the poles cool Earth unevenly

• sunlight is more concentrated in some places on Earth

• the light & heat reflected varies as the Moon changes phases

Winds blow on Earth because

• Ocean waves push air onto the shore & across Earth’s surface

• The gravity of Earth and the Moon push and pull the air

• Earth spins quickly, causing air to blow around

• Warm air rises and cool air falls toward Earth’s surface
