The students in a science class are investigating the differences between the outer core and the inner core of the Earth. What question could they ask to correctly determine the difference between the two layers?

• Why is the outer core hotter than the inner core?

• Why is the outer core denser than the inner core?

• Why is the outer core a liquid and the inner core a solid?

• Why is the outer core composed of rock and the inner core composed of metal?

What is the main cause of the movement of tectonic plates? (where are the convection currents located?)

• Lithosphere

• Asthenosphere/upper mantle

• Outer core

• Inner core

What type of boundary does the model show and what can happen at this boundary?

• The transformation boundary creates an oceanic ridge

• The transformation boundary creates earthquakes

• The convergent boundary creates mountains

• The divergent boundary creates a rift valley

What model BEST represents the movement of tectonic plates that is the main cause of new crust and deep rift valleys?

• Model A, because the plates are converging to create mountains

• Model B, because two oceanic plates are separating

• Model C, because two oceanic plates are separating

• Model C, because the plates are converging to create mountains

Use the information and the image to answer the following question.

The image shows how students use a stream table to model how natural processes like weathering, erosion, and deposition change Earth's surface. Based on the image, what process is the student pointing to in the image?

• The water flowing with sand represents erosion.

• The water hitting the sand represents weathering.

• The water cutting into the sand represents channeling.

• The water with sand depositing at the bottom represents deposition.

What argument BEST explains the difference in species from rock layer 1 to rock layer 2?

• The climate when layer 1 rock was formed allowed for greater diversity in ferns, while the climate when layer 2 rock was formed restricted plant diversity.

• The climate when layer 2 rock was formed allowed for greater diversity in ferns, while the climate when layer 1 rock was formed restricted plant diversity.
