Plate Tectonics Part 1

Front

What happens when oceanic and continental plates collide?

Back

The oceanic plate subducts beneath the continental plate because it is more dense.

Front

What can happen to the lithosphere at plate boundaries?

Back

The lithosphere can be created, destroyed, or remain unchanged.

Front

What causes tectonic plates to move?

Back

Tectonic plates are moved by convection currents in the mantle.

Front

What geological feature forms when two continental plates collide?

Back

A mountain chain is formed when two continental plates collide.

Front

What is magma?

Back

Magma is hot fluid or semi-fluid material below or within the earth's crust from which lava and other igneous rock is formed on cooling.

Front

Define tectonic plates.

Back

Tectonic plates are large sections of the Earth's lithosphere that move and interact with each other.

Front

What is subduction?

Back

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

Front

What is the lithosphere?

Back

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

Front

What are convection currents?

Back

Convection currents are the circular movements of fluid caused by differences in temperature and density, driving plate tectonics.

Front

What is the difference between oceanic and continental plates?

Back

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