Answer:

An index fossil is a fossil used to determine the age of the sediments in which it is found. When quickly approximating the age of new finds, an archaeologist looks at the rocks in which it is buried, as those sediments would have been on the surface at the time of the death of the pre-historic creature.

Explanation:

A fossil is an index fossil when it is distinctive, abundant, and limited in geological areas. A good index fossil lived for a short period of time so that the range of ages of the strata in which the index fossil is located is small. A good index fossil is found in a wide geological range.

A fossil is an index fossil when animals or plants preserved in the rock record of the Earth is characteristic by a particular span of geologic time or environment.

natta225 [31]

Answer:

A) The paper is affected by air resistance due to its flat shape, so wadding the paper into a tight ball would cause it to hit the ground at the same time as the other objects.

Explanation:

<u>I am so sorry if this is incorrect! But after some research, this is what I found. </u>

Aristotle said that there are 4 elements: Earth, Wind, Water, Fire. Objects made of earth (like a rock) will want to go the center of the universe (center of the Earth). Things made of fire want to go to the place where fire is. I guess this would be the Sun - or somewhere up. Aristotle also said that a heavier object will fall at a faster speed.

Here is the first classic example. This is a bowling ball and a basketball dropped from the same height. Normally, people would assume thatn the bowling ball would drop quicker. They are correct. Please note that heavier objects do not always fall faster though.

I hope I answered your question! please give brainliest!
