Hydrosphere

Which describes the hydrosphere?

• all of Earth’s organisms and the environments in which they live

• a layer of Earth’s atmosphere made up primarily of concentrated ozone

• all of the water in Earth’s oceans, lakes, seas, rivers, and glaciers, plus the water in the atmosphere

• watersheds → estuaries → oceans

• watersheds → oceans → estuaries

A water table well and another well going into an aquifer are shown in

the diagram below.

During a drought, the water table dries while the aquifer remains nearly

full. Which best explains this?

• During the drought, the water table increases, but the water level in the confined aquifer increases.

• During the drought, the water table remains constant, but the

  confined aquifer keeps its water level because of other sources of water

• During the drought, the water table falls, but the confined aquifer is mostly isolated from the drought conditions and remains unaffected.

The Ocean is what percentage of all water that is found on earth?

• 3%

• 21%

• 71%

• 97%

Which is the best reason for understanding local watersheds?

• to decide where to place recreational parks

• to help identify non-point source pollution

• to help identify point source pollution

Why is water from an aquifer more likely to be cleaner than water from

other sources?

• because it forms where fresh and salt water meet

• because it receives water directly from precipitation

• because it rises to the surface near the ocean

• because pollutants are filtered by rock and soil deep within Earth

During a portion of the water cycle, waterfalls to Earth’s surface as precipitation. Some of

this water runs off into channels and keeps moving until it ends up in the ocean.

Which BEST describes the water in the channels?

• lake

• river

• aquifer

• wetland

The empty spaces in a material are called pores. Porosity is the amount of empty space

within a material. Permeability describes how well the pores in a material are connected.

Which of these materials would make the MOST effective aquifer?

• a material that has high porosity and high permeability

• a material that has high porosity and low permeability

• a material that has low porosity and high permeability

• a material that has low porosity and low permeability
