Water Cycle, Clouds, and the Atmosphere

Which of the following best describes the water cycle?

• The process through which water is contaminated and polluted.
• The process through which all of Earth’s water moves above, across, and through the Earth’s crust and atmosphere.
• When water is filtered by technology and machines.
• The process through which water is removed from Earth's surface.

As the sun heats the surface of the ocean, it causes the liquid water to change into water vapor. This process is called:

• Evaporation
• Precipitation
• Condensation
• Infiltration

When water vapor rises into the atmosphere, it cools and changes into liquid water. This process is called:

• Evaporation
• Condensation
• Precipitation
• Runoff

When clouds become too heavy with condensed water, that water falls to Earth as:

• Evaporation
• Condensation
• Precipitation
• Runoff

Which of the following is NOT an example of precipitation?

• Rain
• Snow
• Hail
• Clouds

When precipitation falls to the Earth's surface, some can soak into the ground. This process is called:

• Evaporation
• Condensation
• Runoff
• Infiltration

What state of matter is water vapor?

• Solid
• Gas
• Liquid
• Plasma

What is the atmosphere?

• The layers of gases that surrounds the Earth.
• Earth's upper crust that contains all living things.
• All of the water on Earth.
• The layer of molten magma beneath Earth's surface.

Which of the following best describes the mesosphere?

• The layer of the atmosphere closest to Earth where all weather happens.
• The layer closest to space.
• The middle layer where the majority of meteoroids burn up.
• The layer where most satellites are found.

In which layer of the atmosphere does all weather occur?

• Exosphere
• Thermosphere
• Stratosphere
• Troposphere
