Back
Plate Tectonics
The scientific theory that Earth's lithosphere is broken into distinct plates that are in slow, constant motion.
Example: Tectonic plates move slowly, causing Earth's surface to change.

FLASHCARD QUESTION
Front
Lithosphere Noun
[lith-oh-sfeer]
Back
Lithosphere
The rigid outer part of the Earth, which is composed of the crust and the upper portion of the mantle.
Example: The image shows Earth's layers, focusing on the crust and upper mantle, which form the lithosphere.

FLASHCARD QUESTION
Front
Tectonic Adjective
[tek-ton-ik]
Back
Tectonic
Relating to the structure of Earth's crust and the large-scale processes which take place within it.
Example: Arrows show how Earth's crust layers move, explaining tectonic activity.

Front
Theory Noun
[thee-uh-ree]
Back
Theory
A well-substantiated explanation of some aspect of the natural world that is supported by a vast body of evidence.
Example: The image illustrates the scientific method, which is used to develop theories based on evidence.

FLASHCARD QUESTION
Front
Oceanic Crust Noun
[oh-shee-an-ik krust]
Back
Oceanic Crust
The relatively thin, dense part of Earth's crust that underlies the ocean basins and is basaltic in composition.
Example: The image shows oceanic crust forming at a divergent boundary with magma rising between plates.

FLASHCARD QUESTION
Front
Continental Crust Noun
[kon-tuh-nen-tl krust]
Back
Continental Crust
The relatively thick, less dense part of Earth's crust that forms the large landmasses known as continents.
Example: The image shows the continental crust as the thick, less dense part of Earth's crust forming the continents.

FLASHCARD QUESTION
Front
Convection Noun
[kun-vek-shun]
Back
Convection
The movement caused within a fluid by the tendency of hotter, less dense material to rise and colder material to sink.
Example: Warm water rises and cool water sinks, creating a circular motion in the pot.
