Chapter 1: Landform Patterns

3. a large flat to gently rolling region.
8. boundary a place where two plates of the lithosphere move away from each other.
9. soft weak layer under the lithosphere upon which the tectonic plates move.
12. the point on Earth’s directly above the location of an earthquake.
14. molten rock flowing from a volcano.
15. a high flat region that has been lifted by movement of Earth’s surface.
16. Boundary a place where side-by-side platers grind past each other.
18. Boundary a place where two plates of the lithosphere come together.

1. the natural features that make up Earth’s surface.
2. the breaking down of rocks by physical or chemical processes.
4. extremely hot fluid, or semi-fluid material under Earth’s crust.
5. Tectonics the theory that Earth’s surface is made up of rigid plates that are pushed by forces inside the planet.
6. a tool that measures and records the magnitude and duration of a disturbance of the ground especially earthquakes.
7. an opening in Earth’s crust from which molten rock or magma escapes to reach the surface.
10. release of energy through Earth’s crust due to changes taking places beneath it.
11. the base rock of an ancient mountain region that has been worn away leaving a flat rocky landform region.
13. flow a circular motion created when warmer material rises and draws down cooler material, which replaces it.
14. the outer solid layer Earth made up of moving plates.
17. the wearing away of Earth’s surface by wind water of glacial action.
