Back

Mantle

Front

This supports the theory of plate tectonics: Seafloor Spreading, Convection currents, Continental Drift, Evaporation.

Back

Seafloor Spreading

Front

This theory explains why the plates move: Continental Drift, Conservation of Mass, Plate Tectonics, Conservation of Energy.

Plate Tectonics

Front

Tectonic Plates move because of Convection currents in the Core of the Earth. True or False?

Back

False

Front

In which layer do convection currents occur? A, B, C, D.

Back

B

Front

What are tectonic plates?

Back

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

Front

What is the lithosphere?

Back

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

Front

What is the asthenosphere?

Back

The semi-fluid layer beneath the lithosphere where convection currents occur.

Front

What is seafloor spreading?

Back

The process by which new oceanic crust is formed at mid-ocean ridges and older crust is pushed away.

Front

What is continental drift?

Back

The theory that continents have moved over geological time and were once joined together.
