Earth systems quiz

Where two crustal plates collide and one plate is forced under the other into the mantle, it is called a 

• hot spot
• pressure zone 
• surface trace
• subduction zone

According to Plate Tectonic Theory, the reason the plates move is

• Surface winds push the plates
• The weight of the ocean forces the plates to move
• Large monsters under the crust are moving the plates
• Convection currents within the earth's mantle move the plates

The boundary where two plates push together

• Convergent
• Divergent
• Transform
• Sea Floor Spreading

A negative feedback loop is:

• when feedback into the system increases the rate of progress
• seen in the example of increased greenhouse gases leading to global warming
• seen in the example o world population growth
• when a system responds to a change by returning it to its original state

A ________ feedback loop causes a system to change further in the same direction.

• Negative
• Corrective
• Polarized
• Positive
