Earth Science

1. This is a remnant of organisms of the past.
7. Referred to as a vent or a series of vents where lava, ash, and gases are released.
8. Described as any mound or ridge of windblown sand rising to various heights.
9. Shale becomes this by metamorphism.
10. This scale measures the hardness of a mineral by scratch resistance.
12. This is also called intrusive igneous rocks because molten rock solidifies at depth.
14. A thick large mass of ice in remote areas that move very slowly.
15. This process in chemical weathering breaks down a compound using water.
17. A type of boundary that occurs when two plates move toward each other that the heavier plate is subducted.
18. The recorded amplitude of seismic waves from an earthquake source.
19. A part of the Earth that is also the largest.
20. Rocks that have undergone extreme heat and pressure.
21. The most abundant element in the Earth's atmosphere.
23. This results from weathering and uplift transported to different areas.
25. This property describes the reflection of light off a mineral's surface.

2. Referred to be the downward arch of a fold.
3. This is a type of mass wasting where large masses of soil, rock, or regolith are displaced.
4. This natural phenomenon happens when masses of warm moist air are rapidly forced upward into colder, dryer layers.
5. A bend in the rock strata produced by horizontal compressive stresses.
6. Defined as the accumulation of weathered sediments that form different landforms.
11. Defined as the part of the earth where all of the water is at or near the surface.
13. A whirling funnel-shaped cloud whose bottom of the funnel has an extremely low air pressure.
16. Describes the severity of an earthquake on humans and their structures.
22. An exogenic process transporting sediments to different places.
24. Molten rock generated by partial melting of rocks in the Earth’s mantle.
