What is the definition of CONDUCTION?

• When heat is transferred from objects like rays of light or electromagnetically.

• a  hot liquid or air that  expands, becomes less dense, and rises or becomes more dense, and sinks.

• When heat transfers from objects that are touching.

• When heat transfers through the heater or AC in your house.

• high to low

• low to high

• high to high

• It can travel high to low and low to high. 

Uneven heating of Earth's surface creates?

• Global Warming which leads to wind

• Changes in air pressure which leads to wind

• Changes in temperature and then  changes in air pressure which leads to wind

• Seasons

When Earth's rotation causes the wind to curve 

• cloudy 

• Coriolis effect

• high pressure

• low pressure 

Winds are caused by differences in

• precipitation

• humidity

• air pressure

• turbulence
