Water Cycle & Human Impact

Identify the step in which water returns to Earth's surface from the atmosphere in the form of rain, sleet, hail, or snow.

• condensation

• evaporation

• precipitation

• runoff

Time and time again, water cycles through Earth. Therefore, the amount of water on Earth

• increases

• stays the same

• decreases

Plants use water to undergo photosynthesis. They also release water into the atmosphere. Plants contribute to which PART of the cycle with this release of water?

• transpiration

• condensation

• precipitation

• accumulation

What step of the water cycle does this picture show?

• Condensation

• Runoff

• Precipitation

• Evaporation

Describe the role of plants in the movement of water through the water cycle.

• Plants collect water and store it in their cells.

• Plants absorb water and release back into the atmosphere through transpiration.

• Plants cause water to condense into the atmosphere and form clouds.

• Plants release water back into the atmosphere through precipitation.

Which of the following activities could cause the water table of ground water to go down?

• Adding more parks and green areas to a city.

• Conserving the amount of water used in big cities.

• Concrete covering the soil blocking infiltration from taking place.

• More precipitation due to more evaporation in an area.

The precipitation that runs off the land and eventually flows into oceans, rivers, or lakes is called ______.

• runoff

• evaporation

• precipitation

• condensation

Energy power source for starting the continuous process of the water cycle. Without this, there would be NO water cycle.

• the sun

• gravity

• underground hotspots

• electricity

This is a type of evaporation where plants release water vapor into the air, almost like they are "sweating". This is called __________.

• transportation

• transpiration

• translation

• precipitation

When precipitation falls to the ground and soaks into the soil through spaces and cracks in the rocks, this process is called ___________.

• condensation

• runoff

• groundwater

• infiltration
