Plate Tectonics 24

Front

What is Plate Tectonics?

Back

The theory that explains the structure and movement of the Earth's lithosphere, which is divided into tectonic plates that float on the semi-fluid asthenosphere.

Front

What are tectonic plates?

Back

Large, rigid pieces of the Earth's lithosphere that move and interact at their boundaries, causing geological events.

Front

What is a divergent boundary?

Back

A tectonic plate boundary where two plates move away from each other, often resulting in the formation of new crust.

Front

What is a transform boundary?

Back

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

Front

What is a convergent boundary?

Back

A tectonic plate boundary where two plates move towards each other, often resulting in subduction or mountain formation.

Front

What is subduction?

Back

The process where one tectonic plate moves under another and sinks into the mantle, often creating deep ocean trenches.

Front

What geological features are commonly found at divergent boundaries?

Back

Mid-ocean ridges and rift valleys.

Front

What geological features are commonly found at convergent boundaries?

Back

Mountain ranges, deep ocean trenches, and volcanic arcs.

Front

What is the San Andreas Fault?

Back

A transform fault located in California, known for its significant earthquake activity.

Front

How do fossil records support the theory of continental drift?

Back

Fossils of the same species have been found on continents that are now separated by oceans, indicating they were once connected.
