Fossils help us reconstruct plant and animal life in the past as well as their evolutionary processes, which can be either slow or rapid. a. True
b. False

True

Explanation:

When we talk about fossils, we are referring to the remains of organisms that had once lived. These are traces of the organisms that existed in the distant past.

These fossil records help us to reconstruct plant and animal life in the past as well as their evolutionary processes, which can be either slow or rapid.

Fossil records reveal extinct species and help us to make sense of the evolutionary processes on earth.

they float because they are less dense than the water itself

something denser than water, like a rock, will sink to the bottom

it cools slower in the earth meaning the crystals have more time to form than lava on the surface
