Earth Terminology!

4. Under the Asthenosphere, is the strong lower part of the mantle.
5. Mostly made of Iron, from the mantle to the core/center of the Earth, about the size of Mars.
8. Fault in which the two fault blocks move past each other horizontally.
11. Large, gently sloped volcano that forms from repeated, nonexplosive eruptions of lava.
12. Stress that reduces the volume or length of a rock, as that produced by the convergence of plate margins.
13. Fragments of rock that are created by explosive volcanic eruptions.
14. Region where an oceanic plate sinks down into the asthenosphere at a convergent boundary, usually between continental and oceanic plates.
16. The boundary between two tectonic plates that are sliding PAST each other horizontally.
17. Hot liquid that forms when rock partially or completely melts, may include mineral crystals.
20. The process by which new oceanic lithosphere is created at mid ocean ridges as older materials are pulled away from the ridge.
21. Magma that flows onto the Earth's surface.
22. Outermost, rigid layer of the Earth.
23. Boundary between two tectonic plates that are moving AWAY from each other.
25. Stream of fluid propelled by thermal convection.
27. Outermost layer of the Earth, 5-100km thick, thinnest layer.
28. Piece of the Lithosphere that moves around on top of the Asthenosphere.

1. Solid dense center of our planet that extends from the bottom of the outer core to the center.
2. Core is divided into two categories, this one is liquid and surrounds the inner core.
3. Theory Theory that the Earth's lithosphere is divided into tectonic plates that move around on top of the asthenosphere.
5. Earth's major plaetes, known as plate tectonics.
6. Occurs when one or a stack of originally flat and planar surfaces are bent or curved as a result of permanent deformation.
7. A volcano made of alternating layers of lava and pyroclastic material.
9. Amount of force per unit area that is put on given material.
10. Theory that continents can drift apart from one another and have done so in the past.
12. Boundary between two colliding tectonic plates.
15. Mountain that forms when molten rock, called magma, is forced to the Earth's surface.
18. Soft layer of the mantle on which pieces of the Lithosphere move.
19. Layer of the Earth between the crust and the core. Extremely thick, contains most of Earth's mass.
24. Stress which stretches rocks into two opposite directions, the rocks become longer in a lateral direction.
26. Funnel shaped pit around the central vent of a volcano.
