Quiz Answer Key and Fun Facts

1. Which of these is the most specific name for a pure crystalline substance formed naturally in the Earth?

Answer: a mineral

A mineral is a solid substance that occurs naturally and has a crystalline structure.

2. A mixture formed naturally in the Earth is known as?

Answer: rock

A rock is a mixture of minerals.

3. The rock type that forms directly from magma?

Answer: igneous plutonic

Magma is the term for molten rock under the earths surface. Plutonic is volcanic rock that forms under the surface as magma cools whereas volcanic rock is formed on the surface.

4. Glassy pumice would be formed by?

Answer: immediate cooling of lava

The rapid cooling does not allow for crystal formation. This rock is also known as volcanic glass.

5. Most sedimentary rocks are a product of?

Answer: eroding rocks

Although some sedimentary rocks are formed from evaporation, the original minerals came from the erosion of rocks.

6. All metamorphic rocks have?

Answer: been changed

Meta mean change and morph means form. Therefore metamorphic means a change in form or structure.

7. In order for sedimentary rock to become metamorphic rock...

Answer: the parent rock must be buried deeper into the earth

Sedimentary rock under compression and due to depth will melt and eventually change into metamorphic rock.

8. Which of these options can best be said to cause landslides once other factors have changed the stability of the land?

Answer: gravity

Gravity is what causes the land -- soil, rock and all -- to move down.

9. The tendency of a mineral to split easily along a flat surface is called?

Answer: cleavage

Cleavage is how a mineral naturally will break.

10. The gas given off in the acid test of a carbonate mineral is?

Answer: carbon dioxide

By adding HCl to a mineral (the acid test) it can be determined if the mineral has a carbon component.
