Plate Tectonics

Front

What is a Divergent Boundary?

Back

A plate boundary where two tectonic plates move away from each other, often creating new crust as magma rises to the surface.

Front

What is a Convergent Boundary?

Back

A plate boundary where two tectonic plates move towards each other, often resulting in the formation of mountains or subduction zones.

Front

What is the lithosphere?

Back

The rigid outer layer of the Earth, consisting of the crust and the upper part of the mantle.

Front

Who proposed the theory of continental drift?

Back

Alfred Wegener proposed the theory of continental drift, suggesting that continents were once connected.

Front

What are tectonic plates?

Back

Large sections of the Earth's lithosphere that move and interact with each other.

Front

What is subduction?

Back

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

Front

What is the mantle?

Back

The layer of the Earth located between the crust and the outer core, composed of semi-solid rock.

Front

What is a Transform Boundary?

Back

A plate boundary where two plates slide past each other horizontally, often causing earthquakes.

Front

What geological features can form at a convergent boundary?

Back

Mountains, deep ocean trenches, and volcanic arcs can form at convergent boundaries.

Front

What is the outer core?

Back

The liquid layer of the Earth's core located beneath the mantle and above the inner core.
