Topic 4 Quiz - Earth's Water

How is the ocean connected to the water cycle?

• Water evaporates from the ocean, forms clouds, those clouds are blown by the wind to other places, where water returns back to the ground as precipitation.

• Water from the ocean washes up on the shoreline and soaks into the ground to form groundwater.

• Water from the ocean does not connect to water cycle, because there is salt in it.

There is more fresh water on Earth than there is ocean water.

• TRUE

• FALSE

Check four fresh water sources that are included in surface water.

• lakes

• rivers

• atmosphere

• swamps

• ground water

Earth's supply of freshwater is limited because most of the Earth's freshwater is tied up in glaciers and ice caps.

• TRUE

• FALSE

What are tides caused by?

• The gravity of the moon and sun pulling water in the ocean.

• Too much rain over the ocean.

• The pull of Earth's gravity.

• The rotation of the Earth.

Through which process of the water cycle is the ocean connected to all of Earth's water?

• evaporation and precipitation

• evaporation and condensation

• translation and evaporation

• precipitation and translation

Why is it important to maintain Earth's freshwater resources? Select two.

• We don't really need to, because ocean water makes up 95% of the Earth.

• Because only 2.5% of Earth's water is freshwater and we need it to survive.

• Some of the freshwater can be hard to get to because it's in glaciers and ice caps, so then there is even less available.

• Because freshwater is the only resource we use.

What are ocean currents?

• The same thing as tides.

• Water that moves in consistent patterns.

• The direction the waves move.

The process when water evaporates from the surface of the earth, rises into the atmosphere, cools and condenses into rain or snow in clouds, and falls again to the surface as precipitation is called the water cycle.

• TRUE

• FALSE

How does the melting of Arctic ice impact the water cycle?

• It causes less water to be stored in ice and a rise in sea levels.

• It makes more rain, because there is more water to evaporate.

• It make the land get flooded and causes more groundwater.
