Earth's Systems Unit 4

Front

What two sources provide the energy that eventually drives the movement of matter throughout Earth’s systems?

Back

The sun and the earth’s core provide the energy that drive earth’s systems.

Front

What is the geosphere?

Back

The geosphere is composed of all of the rock that makes up Earth.

Front

What are the three main parts of the geosphere?

Back

Crust, mantle (asthenosphere), core

Front

How does energy from Earth’s core transfer through the geosphere?

Back

Energy transfers from the core to the rest of the geosphere by conduction and convection.

Front

How does the flow of energy cause changes to matter in this system?

Back

As rock heats up, it becomes less dense and convection causes it to rise upward toward the crust. In contrast, as rock cools it gets denser and sinks deeper into the mantle.

Front

What is the hydrosphere?

Back

The hydrosphere is composed of all the water on the earth.

Front

How does the flow of energy in the hydrosphere cause changes to matter in this system?

Back

The flow of energy causes changes in density, which is indicated by the convection cells in this system.

Front

What is the likely source for the flow of energy in the hydrosphere?

Back

The sun is the likely source of the flow of energy.

Front

What is the sub category of the hydrosphere that contains all the frozen water?

Back

The cryosphere

Front

What happens to the density of water when it is heated?

Back

The density in the water decreased when the water was heated. Density increased when the water cooled.
