Can You Explain It?

• Our food comes from interactions among Earth's systems.

• The biosphere includes the farmer and plants.

• Water used by the plants is part of the hydrosphere.

• Plants grow in soil, which is part of the geosphere.

• Plants absorb and give off gases that are part of the atmosphere

Open Ended

How do you think Earth's systems are interacting in the image? Answer in complete sentences.

How the Atmosphere and Hydrosphere Interact

• The water cycle involves all of Earth's systems. It takes place all over Earth, and it involves a variety of different processes.

• Remember that a cycle is something that repeats over and over in a pattern.

How the Atmosphere and Hydrosphere Interact

• In the water cycle, water moves among and between Earth's systems.

• It chances forms and locations. There are many different paths that water can take through the water cycle.

Multiple Choice

Snow is most related to _______

• evaporation

• condensation

• precipitation

Multiple Choice

The surfaces of bodies of water are most directly related to ________.

• evaporation

• condensation

• precipitation

Multiple Choice

Clouds are most directly related to _________

• evaporation

• condensation

• precipitation

What Goes Up...

• Water on Earth changes form and location by moving through the water cycle. As water moves through the cycle, it interacts with all of Earth’s spheres. 

• Several of the changes it undergoes in the water cycle demonstrate how the hydrosphere and atmosphere interact.

What Goes Up...

• Evaporation is the process by which a liquid changes to a gas.

• Condensation is the process by which a gas changes to a liquid.

• Precipitation is water that falls from clouds to Earth’s surface.

Case Study: Water and Air Pollution Affects All the Spheres

You’ve learned that water moves through all of Earth’s spheres. As it moves through the water cycle, there are many chances for it to become polluted. Look at the images to see how human actions can affect Earth’s water.

Putting It Together

Trees are part of the biosphere. They need water to survive. They take in water from the soil through their roots and release water vapor into the air from their leaves.  Let's answer some questions about trees and how they interact with the hydrosphere and atmosphere.

Multiple Choice

The tree’s roots take in water from the

soil, which shows an interaction of the geosphere, ________ , and biosphere.

• hydrosphere

• atmosphere

• rockosphere

Multiple Choice

Trees give off water into the _______.

• soil

• air

• clouds

Multiple Choice

Because trees give off water into the air, this shows a relationship between the ________, hydrosphere and biosphere.

• cloudosphere

• cloudosphere

• atmosphere
