Answer:Environmental science is the pursuit of knowledge about the workings of the environment and our interactions with it. Environmentalism is a social movement dedicated to protecting the natural world. Nature makes resources at similar speeds.
Explanation:
The principles of fossil succession and natural selection are connected to Rocks and fossil fuels respectively.
<h3>Define principle of Fossil Succession ?</h3>
A method for determining the relative age of a fossil is through fossil succession. It can put the fossils in chronological order by using the geological strata to identify the rock layers where they are located.
<h3>Principle of fossil selection .</h3>
The law of fossil succession, also referred to as the principle of fossil succession, is based on the observation that sedimentary rock strata contain fossilized flora and fauna and that these fossils succeed each other vertically in a definite, reliable order that can be recognized over considerable horizontal distances.

Answer:
The reason why the ball rolling across carpet will come to a stop faster than the one rolling across concrete is the friction (option B).
Explanation:
The contact surface on which the balls move is different. Irregularities in the carpet cause the ball in it to stop faster. The concrete surface is less irregular, and allows the ball to move a little more and then stop. This is due to friction.
In physics,<u> friction is a force that is capable of opposing movement</u>, since the contact of two surfaces limits its movement. A smooth surface produces less friction than a rough or irregular surface.
Since the friction that stops both balls occurs when they are in motion, it is called dynamic friction, that is, the force that causes a moving body to stop.
