Unit 5 Plate Tectonics

Front

What forms at a divergent boundary between two oceanic plates?

Back

Mid-ocean ridge is formed at a divergent boundary between two oceanic plates.

Front

What geological events are associated with transform boundaries?

Back

Earthquakes are commonly associated with transform boundaries.

Front

What does sea-floor spreading explain?

Back

Sea-floor spreading explains how new crust is created at a divergent boundary.

Front

What is the correct order of Earth’s layers starting from the surface?

Back

The correct order is: crust, mantle, outer core, inner core.

Front

At which plate boundary is new crust formed?

Back

New crust is formed at divergent boundaries.

Front

What is a tectonic plate?

Back

A tectonic plate is a massive, irregularly shaped slab of solid rock that makes up the Earth's lithosphere.

Front

What is the difference between oceanic and continental plates?

Back

Oceanic plates are thinner and denser than continental plates, which are thicker and less dense.

Front

What is subduction?

Back

Subduction is the process where one tectonic plate moves under another and sinks into the mantle.

Front

What is a rift valley?

Back

A rift valley is a lowland region formed by the divergence of tectonic plates.

Front

What are the three types of plate boundaries?

Back

The three types of plate boundaries are divergent, convergent, and transform boundaries.
