8th Science Plate Tectonics

Front

What is Plate Tectonics?

Back

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

Front

What are tectonic plates?

Back

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

Front

What is a transform fault?

Back

A type of fault where two tectonic plates slide past each other horizontally, causing earthquakes.

Front

What is a divergent boundary?

Back

A tectonic boundary where two plates move away from each other, often creating new crust, such as at mid-ocean ridges.

Front

What is a convergent boundary?

Back

A tectonic boundary where two plates collide, leading to subduction or mountain formation.

Front

What evidence supports the theory of plate tectonics?

Back

Fossil distribution, continental fit, geological formations, and seismic activity.

Front

What is convection current?

Back

The movement of fluid caused by differences in temperature and density, driving the movement of tectonic plates.

Front

What is the Great Rift Valley?

Back

A geological feature formed by a divergent boundary, where tectonic plates are pulling apart.

Front

What is the Mid-Ocean Ridge?

Back

An underwater mountain range formed by divergent tectonic plates, where new oceanic crust is created.

Front

What is subduction?

Back

The process where one tectonic plate moves under another, often leading to volcanic activity.
