36
Q

what causes earth movements?

A

forces within the earth when temperature and pressure differences cause instability

41
Q

what is the pacific ring of fire?

A

an area of frequent earthquakes and voclanic erruptions in the Pacific Ocean

42
Q

how do tectonic plates create mountains?

A

compressional forces, isostatic uplift, and intrusion of igneous matter forces surface rock upwards

47
Q

what is evapotranspiration?

A

water from plants and soil rise into the atmosphere

48

what is canopy interception?

A

precipitation that is intercepted by plant foliage

51
Q

what is subserface flow?

A

the flow of water undergrownd

52
Q

what is evaporation?

A

the transofrmation of water form liquid to gas as it moves from the ground to the atmosphere

53
Q

what is condensation?

A

water vapor transofmed into liquid water in the air producing clouds and fog

temperature and moisture differences between different locations

55
Q

what causes pressure differences?

A

surface temperature differences

56
Q

what are the weather differences between land and water?

A

land absorbs and radiates heat faster
water releases heat over long periods of time

57
Q

what causes mountain/valley breezes?

Q

what causes tides?

A

tidal forces of the moon and sun and the earth’s rotation

65
Q

what can tides do?
