Fossils are the remains of plants and animals that have been preserved for millennia in stones under the Earth's surface. They contain the long chapters of the history of our Earth. Fossils tell us what the earth looked like many millions of years ago, what kind of animals and plants lived on its surface and how it was changing. Fossils show us a history of over a billion years old.
From the fossil from a dry, mountainous area we can conclude that the area was once underwater and over time the soil has risen as result of continental drift and uplift. So, a mountain was once the bottom of a prehistoric ocean or sea.

Answer:
D. Fissure
Explanation:
On the image, we have a fissure. The fissure is a linear volcanic vent through which there are eruptions occurring. The fissures are connected with the volcano, but they can be tens of kilometers away from the volcano, or even more. This makes them very dangerous, as they can occur pretty much everywhere around the volcano, suddenly erupting from bellow the ground, making explosions, cracking the ground, and causing fires.
