QUIZ-2- EARTH AND SPACE

1. These are heat-driven cycles that occur in the air, ocean, and mantle. They are caused by a difference in temperature, often due to a differing proximity to a heat source.

It happens when earth soaks up some water and temporarily stores it underground.

1. It is an area of land that channels rainfall and snow melt to creeks, streams, and rivers,  eventually leading to outflow points such as reservoirs, bays, and the ocean.

1. It is one of the leading causes of water pollution around the world.

1. It is an important part of the water cycle because, through this process,  much of the water returns again to the oceans, where a great deal of evaporation occurs

1. It is an important process where rain water soaks into the ground, into the soil and underlying rock layers. Forming water storage beneath the surface

1. One final process is important in the water cycle. As plants absorb water from the soil, the water moves from the roots through the stems to the leaves. What is this process?

1. It is the most essential liquid needed by Humans and other species in order to survive.

As the water moves through the soil and rock layers, many of the impurities in the water are filtered out. Forming what we call the?

1. As we all know. Earth’s surface is covered by water. But how much of Earth’s water is Freshwater?
