:) | its only 3 questions ill give brainliest if your right 1.Which type of rock may result when sedimentary rock is exposed to extreme heat and pressure?

a. clastic

b. extrusive

c. igneous

d. metamorphic

2. In the rock cycle, how does rock become sediment?

a. Through weathering and erosion

b. through crystallization and solidification

c. through heat and pressure

d. through compaction and cementation

3. A Sedimentary rock containing a fern fossil was found. what does this tell about the area at the time the rock was formed?

a. The area was hot

b. The area was covered by and ocean

c. The area was cold

d. The area was on a land

1:(D), 2:(D), 3:(D)

Explanation:

1) When a rock is exposed to heat and pressure, it becomes a metamorphic rock. This is correct, because this is the process that forms a metamorphic rock.

2) A rock becomes sediment through weathering and erosion. In this question, they are not asking you to explain the process of sedimentary rock formation, they are asking you how a rock becomes sediment. The process of weathering and erosion breaks down a rock, and turns that rock into smaller peices, which therefore, through the process of compaction and cementation forms a sedimentary rock.

3) A fern is a land plant. It is not found in the sea and there is not enough information given to tell whether or not the area was hot or cold. This leaves us with D. We can tell that this fossil is a land fossil because ferns do not grow in the ocean.

Hope I could help, and best of luck!

1. (1.2kw)x(15/60hours) = .3kwh --> a

2. (5kw)x(90/60hours)x(8cents/kwh) = $0.60 --> d

3. microwave --> 1200 watts = (1.2kw)x(6/60hours) = .12kwh

coffee-maker --> 900 watts = (.9kw)x(10/60hours) = .15kwh

therefore, it requires more energy for the coffee-maker to do the same amount of work.

so the answer is a.

answer: 21

step-by-step explanation:

divide 630 by 30. 30 goes into 630 21 times
