Water, Hydrological Cycle

Where does the energy that powers the water cycle come from?

• Animal

• Ocean

• Plants

• Sun

What is the correct term for plants releasing water from the stomata of their leaves, which then evaporates?

• Evaporation

• Condensation

• Expiration

• Transpiration

What is the movement of water down through the earth's surface?

• Irrigation

• Infiltration

• Precipitation

• Run-off

Answer explanation

When precipitation hits the ground, it has two options depending on where it is in its story line. It may infiltrate the soil or continue across the land as runoff.

Infiltration occurs when surface water enters the soil. This process is similar to pouring water onto a sponge. The sponge soaks up the water until it can hold no more. At this point, the soil becomes saturated, but the excess water has to go somewhere.

When this happens, we get overflow in the form of runoff, which is when surface water flows over land.

What is evaporation?

• Water freezes.

• Water vapor meets cold air and changes back into liquid.

• Water gets warm and changes from liquid water to water vapor.

• Plants take in water from the soil.

From where does most water evaporate?

• Rivers

• Lakes

• Oceans

• Clouds

Answer explanation

Remember, the oceans hold about 96.5 percent of all Earth's water.

Where does some water from the water cycle collect underground?

• Aquifers

• Groundwater flow

• Watertable

• Lakes

Answer explanation

What exactly is an aquifer?

The saturated area beneath the water table is called an aquifer, and aquifers are huge storehouses of water. ... When a water-bearing rock readily transmits water to wells and springs, it is called an aquifer. Wells can be drilled into the aquifers and water can be pumped out.

What is a water table?

A water table describes the boundary between water-saturated ground and unsaturated ground.

As time goes by, and water goes through the water cycle, again and again, the amount of water on Earth _______.

• Increases

• Decreases

• Remains the same

• Goes up and down

Answer explanation

Water continually evaporates, condenses, and precipitates, and on a global basis, evaporation approximately equals precipitation. Because of this equality, the total amount of water vapor in the atmosphere remains approximately the same over time.

Which of the following is NOT an example of precipitation?

• Vapour

• Sleet

• Rain

• Hail

Answer explanation

What is difference between hail and sleet?

Sleet are small ice particles that form from the freezing of liquid water drops, such as raindrops. ... Sleet is also called ice pellets. Hail is frozen precipitation that can grow to very large sizes through the collection of water that freezes onto the hailstone's surface.

Rain are water droplets that are too heavy to float.

• True

• False

Answer explanation

Within a cloud, water droplets condense onto one another, causing the droplets to grow. When these water droplets get too heavy to stay suspended in the cloud, they fall to Earth as rain.
