Hydrologic Cycle Processes and Concepts

The video explores the hydrologic cycle, emphasizing the distribution and forms of Earth's water. It explains the mechanisms of the water cycle, including the roles of sunlight and gravity. The video highlights the importance of saline and freshwater reservoirs and concludes with a recap of key points.

What is the primary focus of the hydrologic cycle?

• The destruction of water resources

• The movement of water through Earth's reservoirs

• The transformation of water into other elements

• The creation of new water sources

What percentage of Earth's water is found in the oceans?

• 75%

• 10%

• 96.5%

• 50%

Which of the following is a man-made reservoir?

• Lake Mead

• The Pacific Ocean

• The Dead Sea

• The Arctic Ocean

What process involves the conversion of liquid water into vapor?

• Condensation

• Evaporation

• Precipitation

• Infiltration

What is the role of sunlight in the hydrologic cycle?

• It causes water to freeze

• It creates new water

• It drives evaporation

• It prevents water movement

What happens to water vapor when it rises in the atmosphere?

• It turns into ice

• It evaporates further

• It condenses into droplets

• It disappears

Which process describes water falling to Earth due to gravity?

• Transpiration

• Precipitation

• Evaporation

• Sublimation

What is the significance of precipitation in the hydrologic cycle?

• It increases ocean salinity

• It returns fresh water to the continents

• It stops the water cycle

• It prevents water from reaching land

How does gravity affect water on land?

• It pulls water downhill

• It pushes water uphill

• It keeps water stationary

• It evaporates water

What maintains the balance of the hydrologic cycle?

• Sunlight and gravity

• Animal activity

• Wind and temperature

• Human intervention
