Hydrosphere Unit Review

Which would most likely affect the amount of water in a lake used to supply drinking water to the nearby city?

• factory releasing chemical to a lake

• long-term water shortage in the area of the lake

• use of the lake for recreational purposes

• amount of sediment in the lake

Which best explains the relationship between water stored in the ocean and water stored in groundwater?

• water stored in groundwater enters the ocean directly as discharge

• water stored in the ocean remains separate from water stored in groundwater

• water from the ocean enters groundwater directly through the soil by infiltration

• water from ocean evaporates, condenses, and forms precipitation which enters groundwater through the soil

Which best describes the process by which water from the ocean enters the atmosphere?

• infiltration

• precipitation

• evaporation

• condensation

Which of the following contains Most of the water on Earth?

• ocean

• watershed

• atmosphere

• ice and aquifers

Which is true concerning the structure of the hydrosphere?

• there is one ocean with one basin

• Many oceans with many basins

• the ocean is connected to many lakes, watersheds, and waterways

If water is recycled in the atmosphere, which best describes why water availability on Earth is decreasing?

• increase in droughts is slowly reducing freshwater reservoirs

• due to an increase in Earth's temp, evaporation rates continue to increase reducing liquid water on the surface

• Earth's freshwater continues to become more polluted, reducing the supply of freshwater safe for humans to consume

Which is the best reason for understanding local watersheds?

• to decide where to place recreational parks

• help identify non-point source pollution

• help identify point source pollution

Which best describes the characteristics of a river basin?

• land drained by a river and its branches

• land at the mouth of a river where water flows into the ocean

• land formed as a result of a river flooding

• land at the mouth of a river where water flows into the ocean

Which best describes the role of the water cycle?

• circulates existing water on Earth

• reduces pollution

• increases usable supply of Earth's water

Which would most likely result from a decrease in water supply to a watershed?

• increase in ocean water levels

• decrease in lake water levels

• decrease in river basin levels
