The statement "Mass extinctions have occurred several times on Earth" explains the indication of the fossil record. 
<h3>Indication of Fossil fuels:</h3>
Paleontologists are fascinated by the evolution and extinction of fossil species throughout geologic history. To do so, they look at all the fossils that have been preserved in sedimentary rocks. 
The fossil record is what we call it. Paleontologists have been collecting fossils from sedimentary rock layers all over the world for over two centuries. 
Their goal is to figure out how species have evolved over geologic time. It can be used as a geologic timescale once the succession is established. 
Then, if a specific fossil is discovered in a rock, you can determine where it belongs on the geologic timescale. 
Therefore, the correct option is the third sentence.

Deserts are formed by weathering processes as large variations in temperature between day and night put strains on the rocks which consequently break in pieces. Although rain seldom occurs in deserts, there are occasional downpours that can result in flash floods.
