Divergent Plate Boundaries - Connection

Multiple Choice

What is a Fault?

• A fracture in the Earth's lithosphere along which movement has occurred.

• A type of rock formation that is completely solid.

• A geological feature that only occurs underwater.

• A crack in the Earth's surface that does not involve movement.

Multiple Choice

How does plate movement contribute to the occurrence of earthquakes?

• Plate movement causes the Earth's rotation to slow down, leading to earthquakes

• Plate movement has no effect on the occurrence of earthquakes

• Plate movement results in the formation of new ocean basins, reducing the likelihood of earthquakes

• Plate movement causes stress to build up along plate boundaries, leading to the release of energy in the form of earthquakes.

Multiple Choice

What are Divergent Boundaries?

• Plate boundaries where two tectonic plates move away from each other, often creating rifts valleys and ocean ridges.

• Plate boundaries where two tectonic plates collide, forming mountains.

• Plate boundaries that slide past each other, causing earthquakes.

• Plate boundaries that are stationary and do not move.

Multiple Choice

At divergent boundaries plates are moving away from each other. What's happens in the space left between them?

• Magma comes up and cools and hardens making new land

• Air comes up and fills the gap

• Water comes up and fills the gap

• Grass comes up and fills the gap

Multiple Choice

Volcanoes can form at divergent boundaries when which of the following occurs?

• Plates move toward each other causing the more dense plate to sink and melt, which allows for magma to rise back to the surface.

• Plates move apart from each other allowing for less dense magma to rise up from a higher to lower pressure.

• Plates move over top a magma plume creating a line of volcanic mountains.

• Plates move side by side, heating the rock and melting it.
