40
Q

PROTECTION
This layer in the stratosphere is necessary in enabling life on Earth. If it does not exist, harmful rays from the sun would reach the surface of Earth and prevent most organisms from surviving.

A

OZONE LAYER

41
Q

Water is a renewable resource because it is continually circulated across Earth through a process known as the?

A

HYDROLOGIC CYCLE

42
Q

What are the three important processes in the hydrologic cycle?

A

EVAPORATION
CONDENSATION
PRECIPITATION

43
Q

HC
What is evaporation? explain. AWP

A

Evaporation is the process of converting liquid to gas.

Water from the oceans, lakes, streams, rivers, and other
bodies of water undergo this process, and it becomes atmospheric water vapor.

44
Q

HC
What is condensation? explain. C

A

Cloud formation that happens by converting water vapor to liquid form.

45
Q

HC
The water vapor in the atmosphere is stored in the form of clouds and moisture (humidity).

A

TRUE

46
Q

HC
What is precipitation?

A

The process of RELEASING water from
the clouds in the form of rain, snow, sleet, or hail.

47
Q

HC
It is the process of returning water from the atmosphere back to the Earth’s surface.

A

PRECIPITATION

48
Q

The atmosphere is a crucial part of the water cycle as it serves as the reservoir of large amounts of water.

A

TRUE

49
Q

The ______ cycle describes the
movement of water from one area to another by changing states―liquid to vapor to ice and back again. IT IS A NEVER ENDING CYCLE.

A

WATER CYCLE/HYDROLIC CYCLE

50
Q

The atmosphere is an efficient medium to move water around the globe.
