Question

I would like the answers for these Geology questions.

1. There are five criteria that all substances must meet in order to be considered a mineral.  What are they?

2. We have discussed 2 different types of bonding: ionic and covalent.  For each, describe the strength of the bond and provide an example of a substance or material that uses that particular bond.

3. Describe the different histories reflected in igneous rocks with large crystals, small crystals, and glassy (no crystals) textures.

4. What igneous rock is the continental crust made of? What igneous rock is the ocean crust made of? What is the igneous composition of each?

5. Illustrate below the path of sediment from the mountains to the ocean.  Make sure to include the environments: mountains, river, beach, and the deep ocean.  Label what type of sediment you would expect to find in each environment and what sedimentary rock type would result from each type of sediment.

6. What is the difference between foliated and nonfoliated metamorphic rocks?  Why does a foliation form?

7. Draw a picture of an anticline and syncline below and label which is which. What stress causes these folds?

8. Complete the table below, listing the type of feature you would expect to find at each of the following plate tectonic boundary settings.  Gray boxes do not have a specific feature, so leave those blank. Also, place a star in the box that represents the plate boundary type closest to us.

9. There are three types of faults that we’ve talked about.  What stress causes each?  Make a sketch of each below and label them. Which of these is the San Andreas Fault?

10. What 3 gases make up the majority of Earth’s atmosphere?

11. What greenhouse gases are responsible for warming Earth?

12. What is an emergent coastline?  What type of continental margin would you expect to find one on?   What features would you expect to find on an emergent coastline?

13. What is a submergent coastline?  What type of continental margin would you expect to find one on?   What features would you expect to find on a submergent coastline?

14. What is relative age dating?  What is the principle of superposition?  What is the principle of cross cutting?

15.  What is absolute age dating?  What is a halflife?

Explanation / Answer

answer 1 - a mineral is a naturally occuring inorganic solid substance which have a definite chemical composition and regular or ordered atomic structure (atomic arrangement)

so for a substance to consider as a mineral, it has to qualify the following conditions

it has to be solid, inorganic, naturally occuring, had a definite chemical composition, and a regular atomic arrangement
