Water Distribution and Water Cycle Quiz

What percentage of the earth's surface is covered by water?

• 50%

• 71%

• 90%

• 30%

When plants release water vapor through their leaves it's called ____________.

• Evaporation

• Condensation

• Precipitation

• Transpiration

What is the primary source of liquid freshwater on earth?

• Underground aquifers

• Oceans

• Precipitation

• Glaciers

When water infiltrates through the soil it goes to ___________.

• Aquifers and ground water

• Rivers and Lakes

• The ocean

• into the atmosphere

How are glaciers formed?

• Snow on mountain tops compacts. Then the compacted snow moves down the mountain as a frozen river

• Rain on the side of a mountain melts as it flows down the mountain creating a glacier

• Snow fills up valleys forming a frozen river and carves them deeper as the frozen river moves through them

• Glaciers only form in Antarctica during heavy rainfall

What is evaporation in the water cycle?

• The process of water cooling into a gas and sinking into the ground

• The process of water heating up and turning into vapor and rising into the atmosphere.

• The process of water turning into a gas and staying in the same place

• The process of liquid water cooling into solid ice

What is condensation in the water cycle?

• The process in the water cycle where water turns into ice.

• The process in the water cycle where liquid water turns into water vapor.

• The process in the water cycle where water vapor turns into snow.

• The process in the water cycle where water vapor turns into liquid water.

What is precipitation in the water cycle?

• Water rising from the Earth's surface to the atmosphere

• Water falling from the atmosphere to the Earth's surface

• Water evaporating from the Earth's surface into the atmosphere

• Water freezing in the atmosphere and forming clouds

What is runoff in the water cycle?

• The flow of water from land to rivers, lakes, and oceans after precipitation.

• The process of water seeping into the ground and becoming groundwater.

• The evaporation of water from the surface of the Earth.

• The movement of water from the ocean to the atmosphere.

What is infiltration in the water cycle?

• The process by which water is transported from the soil to the atmosphere

• The process by which water flows from the soil to the ground surface

• The process by which water evaporates from the soil

• The process by which water on the ground surface enters the soil.
