What is the Earth's crust primarily composed of?

• Water

• Gas

• Molten rock

• Hard outer rock layer

What are tectonic plates?

• Very slowly, only a few centimeters each year

• Not at all, they are stationary

What geological event is common along transform boundaries?

• Volcano formation

• Tsunamis
