How is the crust DIFFERENT from the other layers of the Earth?

How are the crust and the inner core ALIKE?

• • They are both solid.

• • They both have the same temperature.

• • They are both under the same pressure.

• • They are both very close to the center of the Earth.

The driving force of the tectonic plates are convection currents, where can these be found?

• inner core

The Ring of Fire is an area where a large number of earthquakes and volcanic eruptions occur. What claim can be made about the Ring of Fire from this information?

• It is the only place on Earth where earthquakes can happen.

• The edges of the tectonic plates are moving in this area.

• It represents the areas where tectonic plates are the thickest.

• It has been getting larger since Earth first formed.

What does the theory of continental drift state?

• The continents were once joined in a super-continent and have moved over time

• Continents are stationary and do not move

• The Earth is broken into lithospheric plates that move due to convection currents

• none of the above
