Why would a planetary geologist study the 4 rocky planets when trying to determine if life exists beyond Earth?

• Because the rocky planets have a solid surface like Earth does

• Because they are the closest to the sun

• Because it is as far as our telescopes can go

Why would Earth be considered a system?

• Earth is a system because we have the sun that provides us with the stuff we need to survive

• Earth is a system because there are parts called spheres that work together to make sure Earth functions as a whole

• Earth is a system because we have a geosphere, atmosphere, biosphere, thermosphere, and hydrosphere

The biosphere consists of:

• The features of the land

• The water that exists on a planet

• The gases that surround a planet

• The life that exists on a planet

The hydrosphere consists of:

• The features of the land

• The water that exists on a planet

• The gases that surround a planet

• The life that exists on a planet

The geosphere consists of:

• The gases that surround a planet

• The water that exists on a planet

• The life that exists on a planet

• The features of the land

The atmosphere consists of:

• The gases that surround a planet

• The features of the land

• The life that exists on a planet

• The water that exists on a planet

Which is NOT an example of a system?

• A stuffed animal that is pushed onto the floor
