Three World Interactions

Robert is performing a series of experiments to show how Earth’s systems interact with each other. He places two jars with thermometers outside in the sun for six hours. One of the jars is covered with the top half of a soda bottle.

In six hours, the temperature in the (uncovered jar / covered jar) will have increased more compared to the (covered jar / uncovered jar).

• uncovered / covered jar

• covered / uncovered jar

Robert says the soda bottle covering the jar models Earth’s atmosphere. The increase in temperature represents how heat is trapped on Earth. This is important for the (biosphere / geosphere) because Earth needs to be (cold / warm) enough to support living things.

• biosphere / cold

• geosphere / warm

• biosphere / warm

• geosphere / cold

Look at the picture

This picture models the dependent relationship between Earth’s spheres, in which they are constantly (competing / interacting) with each other.

• competing

• interacting

The picture shows how quickly the landscape can change due to a shift in one of Earth’s spheres.

Silvio made this model to use in a science project.
