The figure below shows how water is distributed on Earth.

Which of the following contains the largest percentage of Earth’s fresh water?

• lakes

• groundwater

• glaciers and ice caps

• ground ice and permafrost

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

During a portion of the water cycle, water falls 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

Which two statements in the table are true about the changing salt concentrations of ocean water?

A - When Earth’s ice

increases, ocean water gets saltier.

B - When Earth’s ice

increases, ocean water gets less salty.

C - When ocean water

evaporates, the water gets saltier.

D - When ocean water

evaporates, the water gets less salty.

• A and C

• A and D

• B and C

• B and D

The water cycle has no beginning or end, but it has an order. Which of the following are the MOST likely ways that water would move through the water cycle?

1 - ocean to river to lake to atmosphere

2 - aquifer to ice cap to ocean to atmosphere

3 - atmosphere to watershed to river to ocean

4 - atmosphere to ocean to atmosphere to ocean

• 1 and 2

• 2 and 3

• 3 and 4

• 4 and 1

The water cycle has no beginning or end, but it has an order. Which of the following are the MOST likely ways that water would move through the water cycle?

• lakes

• rivers

• oceans

• aquifers

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

• the oceans

• watersheds

• the atmosphere

• ice and aquifers

Which factor has the greatest effect on a community’s stores of fresh water?

• the location of the nearest ocean

• the average annual rainfall

• the location of the nearest mountain

• the average winter temperature

Which type of water reservoir could always provide fresh water?

• inland lakes

• river deltas

• mountain glaciers

• tropical seas

Which factors can have the greatest effect on the health of a river system?

• type of soil and salinity

• nitrate levels and turbidity

• human consumption and pH

• natural disasters and tidal changes
