Q

What is Earths hydrosphere?

A

Liquid water

17
Q

If a warm object is in contact with a cooler one, what will cause heat transfer? What happens to the temperature of each object?

A

Conduction. The cool object will get warmer, and the warm object will get cooler

18
Q

What causes water to warm more slowly than land?

A

Water has a higher specific heat than land.

19
Q

If water is placed in the sun, what will happen to its volume and kinetic energy?

A

Both the volume and the kinetic energy will increase.

20
Q

The transfer of energy due to the movement of matter.
Ex. Water boiling in a pot
Hot water rises, while cooler water from other parts of the pot sink and replace the rising water.

A

Convection

21
Q

What is the most abundant gas in Earths atmosphere?

A

Nitrogen
