CA- Depositional Environments

1. What is the definition of a Depositional Environment (include source) (1 pt):

2. Re-write that definition in your own words (3 pt):

3. There are three main types of Depositional Environments, they are (3pt):

1.

2.

3.

4. Using the 3 main types you just listed, Complete the next 3 questions (6pt):

In a Depositional Environment, the energy of that environment is:

(circle one) high/medium/low

In a Depositional Environment, the energy of that environment is:

(circle one) high/medium/low

In a Depositional Environment, the energy of that environment is:

(circle one) high/medium/low

5. Thinking about your answer to the energy question above, what kind of rock (NOT igneous, sedimentary or metamorphic) would you find in each environment? – list the rock with its environment (*hint envision that environment and think about the sediment that would be carried by that environment, what rock does that sediment produce?) (6 pt)

6. List 3 modern depositional environments that you can think of and explain why they are depositional Environments

(example: Cape Cod, MA – it has a spit growing- sand is being carried and deposited by Longshore Drift)

7. Of the Following geologic locations, write what main environment (from question 3) it is under:

Alluvial -

Deltaic-

Tidal-

Reef-

Aeolian-

Lake-

8. Many people often wonder, why does Geology matter? So, lets dip our toe into that question 12 pts):

Sand is one of the most common types of sediments found in a depositional environment. Sand is a very broad term and varies from beach to beach – it all depends on where its source comes from.

Go to https://www.sandatlas.org/sand-minerals/ - this website lists all the common minerals found in sand. I want you to research 3 of them – try and pick 3 you didn’t know about before and tell me (1) what they are used for (2) where are they commonly found and (3) what would you not be able to have, if the mineral did not exist. (no need for sources for this assignment, a quick web search is fine)
