HW: 4.1 Plate Tectonics

What is the lithosphere?

• The central core of the Earth

• A thin layer of rock floating on magma

• The layer where magma is formed

• A dense oceanic plate

Tectonic plates are sections of which Earth layer?

• Mantle

• Core

• Lithosphere

• Asthenosphere

Which plate boundary type involves plates moving away from each other?

• Convergent

• Divergent

• Transform fault

• Subductive

What geological formation is primarily created by convergent continental plate boundaries?

• Mid-ocean ridges

• Rift valleys

• Mountains

• Hotspots

What is the main cause of magma rising to the Earth’s surface at divergent boundaries?

• Tectonic plate collisions

• Cooling of the mantle

• Heated magma pushing plates apart

• Subduction of one plate under another

• A) Mid-ocean ridges

• B) Coastal mountains and volcanoes

• C) Rift valleys

• D) Subduction zones without mountains
