Water Cycle Review (6.3.1)

Water continuously moves between living organisms, such as plants, and non-living things, such as clouds, rivers, and oceans. The water cycle does not have a starting or ending point.

Most precipitation that occurs over land is not absorbed by the soil. This water remains

on the surface and is called __________ which collects in streams and rivers and eventually

flows back into the ocean.

• infiltration

• runoff

• collection/accumulation

• condensation

Water also moves through living organisms. Plants soak up large amounts of water through their roots. The water then moves up the plant and evaporates from the leaves in a process called __________________.

• evaporation

• infiltration

• runoff

• transpiration or evapotranspiration

When a parcel of air containing gaseous water molecules is heated by the Sun, it will expand. This decreases the density of this particular parcel of air, so that it weighs less. It will then be pushed upward by colder, denser air that is pulled downward and underneath it by gravity. This is an explanation of what step in the water cycle?

• evaporation

• condensation

• precipitation

• collection/accumulation

Any time water vapor molecules in the air slow down, they turn back into liquid water. This happens high up in the atmosphere where it's cooler; water vapor rising up in the air cools and forms clouds. This is an explanation of which step in the water cycle?

• evaporation

• condensation

• precipitation

• collection/accumulation

As cloud droplets collide they merge to form larger drops. If the drops become large enough, the force from the rising air is no longer strong enough and the drops will fall to the ground as rain, snow, sleet, or hail. This is an explanation for which step in the water cycle?

• evaporation

• condensation

• precipitation

• collection/accumulation
