____________________________ 1. A fault in which the two fault blocks move past each other horizontally.
____________________________ 2. A piece of the lithosphere that moves around on top of the asthenosphere.
____________________________ 3. The theory that the Earth’s lithosphere is divided into tectonic plates that move around on top of
the asthenosphere.
____________________________ 4. The amount of force per unit area that is put on a given material.
____________________________ 5. The bending of rock layers due to stress in the Earth’s crust.
____________________________ 6. The boundary between two colliding tectonic plates.
____________________________ 7. The central, spherical part of the Earth below the mantle.
____________________________ 8. The layer of the Earth between the crust and the core.
____________________________ 9. Literally, the “middle sphere”-the strong, lower part of the mantle between the asthenosphere
and the outer core.
____________________________ 10. The process by which new oceanic lithosphere is created at mid-ocean ridges as older
materials are pulled away from the ridge.
____________________________ 11. The boundary between two tectonic plates that are sliding past each other horizontally.
____________________________ 12. A fault in which the hanging wall moves down relative to the footwall.
____________________________ 13. The type of stress that occurs when an object is squeezed.
____________________________ 14. The thin, outermost layer of the Earth, or the uppermost part of the lithosphere.
____________________________ 15. The solid, dense center of the Earth.
____________________________ 16. The liquid layer of the Earth’s core that lies beneath the mantle and surrounds the inner core.
____________________________ 17. The theory that continents can drift apart from one another and have done so in the past.
____________________________ 18. A fault in which the hanging wall moves up relative to the footwall.
____________________________ 19. The type of stress that occurs when forces act to stretch an object.
____________________________ 20. A break in the Earth’s crust along which two blocks in the Earth’s crust slide relative to one
another.
____________________________ 21. The boundary between two tectonic plates that are moving apart from each other.
____________________________ 22. The region where an oceanic plate sinks down into the asthenosphere at a convergent
boundary, usually between continental and oceanic crust.
____________________________ 23. The outermost, rigid layer of the Earth that consists of the crust and the rigid upper part of the
mantle.
____________________________ 24. The soft layer of the mantle on which pieces of the lithosphere move.
