Water that flows across the land without infiltrating (soaking in) is called:

• runoff

• precipitation

• transpiration

• evaporation

Which of the following best describes how water flows across land?

• direction depends on the weather at the time

• always downhill due to gravity

• always flows south due to gravity

• it is impossible to predict the flow of water.

All of the land area that supplies water to a particular river system is called its

• surface water

• divide

• ridge system

• watershed

About 20% of Earth's water is below the surface. This water is called

• groundwater

• salt water

• fresh water

• spring water

Rock and soil underground can store water in spaces between its particles. This is a(n)

• impermeable layer

• aerated zone

• aquifer

• river system

Layers containing spaces, or pores, through which water can pass are called:

• permeable

• saturated

• aerated

• impermeable

There are some layers of rock underground that water cannot pass through. Such layers are described as:

• permeable

• impermeable

• aerated

• saturated

In an aquifer, the zone of saturation:

• has pore spaces filled with air

• has pore spaces filled with water

• has pore spaces that are large

• has very few pore spaces

The upper layer of an aquifer has air in its pore spaces. This layer is therefore called the

• zone of saturation

• recharge zone

• permeable layer

• aerated zone
