The Earth System

Which of the following is not a system on our planet?

• hydrosphere
• biosphere
• geosphere
• asthenosphere

Which system makes up the air above us?

• atmosphere
• geosphere
• hydrosphere
• biosphere

The hydrosphere moves energy through...

• conduction
• convection
• radiation
• tides

Which is the bottom most layer of the atmosphere?

• troposphere
• thermosphere
• mesosphere
• stratosphere

Which layer has the ozone layer in it?

• stratosphere
• troposphere
• thermosphere
• mesosphere

Why does the stratosphere warm up?

• The layer is closer to the sun so gets more radiation
• the ozone layer absorbs heat and acts like a blanket
• heat and light radiate onto the earth and then reflect back up warming it

Which layer burns up meteors?

• mesosphere
• troposphere
• thermosphere
• stratosphere

When a warm object is next to a cold object, which way does energy move?

• It does not move.
• It conducts from the warm object to the cold object
• it conducts from the cold object to the warm object
• it moves both directions

Temperature is a measure of...

• the amount of heat in an object
• how much energy something has
• the average speed of the particles in something

Which type of energy transfer does not need matter to move through?

• convection
• conduction
• radiation
• transfer
