In Which Type Of Rock Were The Fossils Most Likely Found?

Almost all fossils are preserved in sedimentary rock . Organisms that live in topographically low places (such as lakes or ocean basins) have the best chance of being preserved.

Which type of rock is most likely to be found?

Sedimentary rock has the most fossils. Recall that sedimentary rock is created as layers of sediment pile on one another and are compressed together. Organisms can get caught between the layers when they die and become fossilized.

What do all rocks have in common?

All rocks have temperature in common. Temperature is the factor that determines the composition of these rocks.

Which conditions are needed to form fossils quizlet?

Fossils usually form when sediment buries a dead organism . As sediment piles up, the organism’s remains are subjected to pressure and heat. These conditions force gases and liquids from the body. A thin film of carbon residue is left, forming a silhouette of the original organism called a carbon film.

Which statement best describes fossil record?

What do the three major types of rocks have in common?

There are three main types of rocks: sedimentary, igneous, and metamorphic . Each of these rocks are formed by physical changes—such as melting, cooling, eroding, compacting, or deforming—that are part of the rock cycle. Sedimentary rocks are formed from pieces of other existing rock or organic material.
