Theory of Plate Tectonic & Plate Boundaries

Front

What is the source of energy that drives plate movement?

Back

Convection currents in the asthenosphere.

Front

Which lithospheric boundary creates uplifted, folded, and faulted mountain belts as its main surface features?

Back

Continental - Continental Convergent Plate Boundaries.

Front

Which lithospheric boundary creates trenches and continental arc volcanoes as its main surface features?

Back

Oceanic - Continental Convergent Plate Boundaries.

Front

What geological feature is created by convergent plate movement?

Back

Mountains.

Front

What is the dense, solid center of Earth made of iron and nickel called?

Back

Inner Core.

Front

What are the three types of plate boundaries?

Back

Convergent, Divergent, and Transform boundaries.

Front

What occurs at divergent plate boundaries?

Back

Plates move apart, leading to the formation of new oceanic crust.

Front

What is subduction?

Back

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

Front

What geological features are commonly associated with oceanic-oceanic convergent boundaries?

Back

Trenches and volcanic island arcs.

Front

What is the asthenosphere?

Back

A semi-fluid layer of the mantle that allows tectonic plates to move.
