At which type of plate boundary do the tectonic plates move apart, causing new crust to form?

• divergent

• merging

• transform

Which statement best describes transform boundaries?

• Two tectonic plates move away from each other.

• Crust is neither created or destroyed.

• One plate sinks below another and is melted.

Which sentence does not describe a super volcano?

• Pressure from magma builds up to create an explosion.

• They erupt frequently.

• Their eruptions can have worldwide impacts.

In which type of boundary do tectonic plates move towards each other?

• convergent

• transform

• hotspot

If scientists wanted to study the youngest rock at a mid-ocean ridge, where should they look?

• at the rocks that make up the smooth seafloor

• at the rocks that are at the top of the ridge itself

• All rocks on the ocean floor are the same age.

• Bassam

• Ezekial

• Both are correct.
