Plate Tectonic Theory and Earth Structure

Vocabulary flashcards covering plate tectonic theory, Earth structure, lithosphere, tectonic plates, and subduction.

Plate tectonic theory

The theory explaining that Earth has a three-layered structure (core, mantle, crust), the lithosphere is broken into huge pieces called tectonic plates which are constantly moving, and plate movements result in landforms and phenomena.

Lithosphere

The layer of the Earth consisting of the crust and uppermost mantle, which is broken up into huge pieces called tectonic plates.

Internal structure of the Earth

The three-layered structure of the Earth comprising the core, mantle, and crust, along with the lithosphere and asthenosphere.
