What is a Cast Fossil?

Back

A type of fossil that forms when a mold of an organism is filled with minerals, creating a replica of the original organism.

Decomposers break down and digest dead organisms, returning nutrients to the soil and helping to maintain soil health.

Front

What is a Body Fossil?

Back

A type of fossil that consists of the preserved remains of an organism, such as bones or shells.

Front

What is a Divergent Boundary?

Back

A type of plate boundary where two tectonic plates move away from each other, often resulting in the formation of new crust, such as mid-ocean ridges.

Front

What is a Transform Boundary?

Back

A type of plate boundary where two tectonic plates slide past each other horizontally, often causing earthquakes.

Front

What is topsoil?

Back

The uppermost layer of soil, rich in organic material and nutrients, where most plant roots grow.

Front

What is a Mold Fossil?

Back

A type of fossil that forms when an organism leaves an impression in sediment, which hardens into rock.

Front

What is a Trace Fossil?

Back

A type of fossil that provides evidence of the activity of organisms, such as footprints, burrows, or feces.
