Earths Interior

2. The strong, lower part of the mantle between the asthenosphere and the outer core
3. The thin and solid outermost layer of Earth above the mantle
6. The hypothesis that a single large landmass broke up into smaller landmasses to form continents, which then drifted to their present locations: the movement of continents
9. the process by which new oceanic lithosphere (sea floor) forms when magma rises to Earth's surface at mid-ocean ridges and solidifies, as older, existing sea floor moves away from the ridge
10. The solid, outer layer of Earth that consist of the crust and the rigid upper part of the mantle The layer of rock between the Earths crust and core

1. Plate tectonics is the generally accepted scientific theory that considers the Earth's lithosphere to comprise a number of large tectonic plates which have been slowly moving since about 3.4 billion years ago.
4. The soft layer of the mantle on which the tectonic plates move
5. a system of ideas that explains many related observations and is supported by a large body of evidence acquired through scientific investigation
7. The central part of Earth below the mantle
8. The layer of rock between the Earths crust and core
