Earth Science

3. This is a remnant of organisms of the past.
6. Described as any mound or ridge of windblown sand rising to various heights.
8. A bend in the rock strata produced by horizontal compressive stresses.
11. This scale measures the hardness of a mineral by scratch resistance.
12. This era is considered as the Age of Mammals.
15. Referred to as the material deposit of a stream.
16. This is a horizontal zone located seaward of the coastal zone's low tide mark.
17. Defined as the accumulation of weathered sediments that form different landforms.
19. This natural phenomena happens when masses of warm moist air are rapidly forced upward into colder, dryer layers.
23. The person who suggested that continents were all originally part of a supercontinent.
24. This is the coldest biome.
25. A part of the Earth that is also the largest.

1. This is also called intrusive igneous rocks because molten rock solidifies at depth.
2. A thick large mass of ice in remote areas that move very slowly.
4. Referred to be the downward arch of a fold.
5. When a volcano erupts, these solid particles are thrown out.
7. An exogenic process transporting sediments to different places.
9. A type of boundary that occurs when two plates move toward each other that the heavier plate is subducted.
10. This process in chemical weathering breaks down a compound using water.
13. This is a type of mass wasting where large masses of soil, rock, or regolith are displaced.
14. The most abundant element in the Earth's atmosphere.
18. A huge landmass that gradually broke apart and drifted to the continents' present position.
20. This property describes the reflection of light off a mineral's surface.
21. A whirling funnel-shaped cloud whose bottom of the funnel has an extremely low air pressure.
22. Shale becomes this by metamorphism.
