Which of the following describes what Earth's core is made up of and why it has that composition?

• Earth's core is made of iron and nickel because they are the least dense elements that make up the Earth.

Why is Earth's inner core solid?

• Earth's inner core is solid because it is at a low temperature.

• Earth's inner core is solid because of the pressure from the layers above it.

• Earth's inner core is a solid because the elements that make it up are only found as solids.

• Earth's inner core is solid because it is at a very high temperature.

One theory about how plate tectonics occur is called ridge push. To what does this refer?

• a force causing plates to enter the mantle at the mid-ocean ridge

• a force causing plates to move away as new magma rises up and forms new ocean crust

• a force causing plates to collide with each other at the mid-ocean ridge

• a force that rips plates apart and causes rock to return to the mantle
