Question 7

The hydrologic cycle describes the continuous movement of water on, above, and below the Earth’s surface.

Answer 7

True

Question 8

Groundwater flow within a watershed is faster than surface runoff.

Answer 8

The cryosphere refers to the frozen components of the Earth’s hydrologic cycle.

Answer 11

True

Question 12

The movement of water in the hydrologic cycle is unidirectional.

Answer 12

False

Question 13

Water vapor in the atmosphere does not contribute to the hydrologic cycle.

Answer 13

False

Question 14

A watershed’s outflow is typically measured at its outlet, such as a river mouth.

Answer 14

True

Question 15

The hydrologic response of a watershed to precipitation depends on land use and soil type.

Answer 15

True

Question 16

Infiltration capacity of soil increases as the soil becomes more saturated.

Answer 16

False

Question 17

Transpiration is the release of water vapor from plants into the atmosphere.

Answer 17

True

Question 18

Urbanization generally decreases runoff within a watershed.

Answer 18

False

Question 19

Water storage in glaciers and ice caps is considered a short-term storage component of the hydrologic cycle.

Answer 19

False

Question 20

The hydrologic cycle has no role in shaping the Earth’s surface features.

Answer 20

False

Question 21

Evaporation rates increase with higher temperatures, wind speed, and lower humidity.

Answer 21

True

Question 22

Evaporation occurs only during the daytime when the sun is present.

Answer 22

False

Question 23

Impervious surfaces in urban areas reduce infiltration in a watershed.

Answer 23

True

Question 24

Evaporation rates are higher in humid climates than in arid climates.

Answer 24

False

Question 25

Deserts have a high rate of evapotranspiration compared to humid regions.

Answer 25

False

Question 26

Watersheds are static and cannot change due to natural or human activities.

Answer 26

False

Question 27

Overland flow occurs when the infiltration rate of soil is greater than the rainfall intensity.

Answer 27

False
