Question

In which rock type do we find them? Why are they important? What are some different types?

a) Fossils are found in igneous rocks. They are essential for tracking geological history. Types include pyrite fossils, granite fossils, and basalt fossils.
b) Fossils are found in sedimentary rocks, preserving evidence of ancient life. Types include petrified wood, ammonites, and trilobites.
c) Fossils are found in metamorphic rocks, providing insights into rock formation. Types include marble fossils, schist fossils, and gneiss fossils.
d) Fossils are found in volcanic rocks. They are essential for understanding volcanic processes. Types include pumice fossils, obsidian fossils, and andesite fossils.

Answer 1

Fossils are found in sedimentary rocks, which preserve evidence of ancient life. They are important for understanding Earth's history, including past environments and species evolution.

Step-by-step explanation:

Fossils are found in sedimentary rocks, which preserve evidence of ancient life. Sedimentary rocks are formed when broken pieces of other rocks or the shells of living organisms are deposited and cemented together without melting.

Fossils are important because they provide insights into Earth's history, helping us understand past environments, the evolution of species, and the age of rocks. Some different types of fossils found in sedimentary rocks include petrified wood, ammonites, and trilobites.
