Scientists are studying a layer of sedimentary rock and discover what appears to be ripples made by running water preserved in the rock. When comparing those ripples to some made in mud at a present day location, they notice that the effects are identical.

Based on the observations, which of the following is most likely to be true?
A.
The environment and conditions of both areas are exactly the same.
B.
Events that occurred in the past were dramatically different from those of today.
C.
The mud at the present day location is actually from the same time period as the rock.
D.
Some events that occurred in the past are similar or identical to events in the present.

Answers

Answer 1
The answer would be D.

As for The other options, it cannot be A because there is no way we could know if they are exactly similar. B states they are dramatically different when there is obviously some similarity. C states that they are from the same time period, which is impossible as there is no way a layer of sedimentary rock can be the same age as current day mud. There are likely many layers above the studied area that can denote the age.
Answer 2

Answer:

D. Some events that occurred in the past are similar or identical to events in the present.

Use the properties of seawater to describe the characteristics of mixtures.

Answers

Seawater is a heterogeneous mixture with dirt and mud particles. It is a homogeneous mixture with dissolved substances.

What are mixture?

A mixture is made up of two or more substances that are not chemical combined together. This is because there is not bond formation between the substances.

A mixture can either be heterogeneous or homogeneous mixture.

A heterogeneous mixture is made up of different compositions which are visible to the eye when seen. Example is mixture of dirt and mud.

A homogeneous mixture is of uniform composition. Example is the mixture of salt and water.

Therefore seawater can be used to describe the characteristics of mixtures because it contains both homogeneous and heterogeneous mixtures.

What happens during coal formation after plants die and fall to the bottom of a swamp.

Answers

Answer:

Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

Explanation:

When plants die, they are no longer in contact with the air. The pressure of rocks and the earth makes the plant matter undergo a chemical change witch transforms the plant matter into coal. The process takes millions of years. This is one of the reason why coal is a non-renewable natural resource.
