Tectonic Plate Boundaries

What type of boundary is associated with the formation of new crust?

• Divergent boundary.

• Convergent boundary.

• Transform boundary.

• Subduction boundary.

Which layer of the Earth is characterized by rock that is plastic and can flow?

• Lithosphere

• Asthenosphere

• Mesosphere

• Outer Core

What is the outermost, rigid layer of the Earth called?

• Asthenosphere

• Lithosphere

• Mesosphere

• Hydrosphere

What geological feature is commonly formed at divergent boundaries?

• Mid-ocean ridges.

• Mountain ranges.

• Volcanic islands.

• Deep-sea trenches.

What is the process called when one tectonic plate is forced under another?

• Subduction

• Convergence

• Divergence

• Transform

What type of boundary is formed when two tectonic plates slide past each other?

• Divergent boundary

• Convergent boundary

• Transform boundary

• Subduction boundary

What happens to tectonic plates at transform boundaries?

• They slide past each other without creating or destroying crust.

• They collide and create mountains.

• They move apart and form new crust.

• They sink into the mantle and disappear.

What is the layer of the Earth that includes the crust and the upper part of the mantle?

• Lithosphere

• Asthenosphere

• Mesosphere

• Core

What geological feature is formed at convergent boundaries?

• Volcanoes

• Mountains or deep ocean trenches

• Plateaus

• Rift valleys

What is the term for the movement of tectonic plates?

• Plate tectonics

• Continental drift

• Seafloor spreading

• Subduction zones
