Which theory explains how large pieces of the lithosphere, called plates, move and change shape?

What is the boundary between tectonic plates that are moving away from each other called?

What is a piece of the lithosphere that has a unique geologic history and may be part of a larger piece of the lithosphere, such as a continent?

What is the hypothesis that states the continents once formed a single landmass, broke up, and drifted to their present locations?

What is the solid, outer layer of Earth that consists of the crust and the rigid upper part of the mantle?

What is the boundary between tectonic plates that are colliding called?

What is the process by which supercontinents form and break apart over millions of years?

What is a long, undersea mountain chain with a steep, narrow valley at its center, formed as magma rises from the asthenosphere?

What is the solid, plastic layer of the mantle beneath the lithosphere, made of mantle rock that flows very slowly?

What was the single, large ocean that covered Earth's surface during the time the supercontinent Pangaea existed?

What is the study of the alignment of magnetic minerals in rock, specifically as it relates to the reversal of Earth's magnetic poles?

What is the boundary between tectonic plates that are sliding past each other horizontally called?

What was the supercontinent that formed 300 million years ago and began to break up 250 million years ago?

What is the process by which new oceanic lithosphere forms as magma rises to the Earth's surface and solidifies at a mid-ocean ridge?
