Pre-Cambrian

5.

1 point

Which fossil type is formed by a carbon imprint between rock layers?

Carbonized

Cast

Trace

Mold

6.

1 point

Which branch of science deals with studying rocks on and within the Earth?

Chemistry

Geology

Ecology

Hydrosphere

7.

1 point

How does the heat of the Earth's core affect the surface of the Earth?

The core's heat provides the atmosphere with its heat.

The core's heat is passed to the crust, which expels it during lava eruptions.

Core's heat is passed into the mantle, which creates convection that moves the crust.

Core's heat is passed around the Earth through earthquakes.

1 point

Why do geologists use index fossils?

To carbon-14 date the rock layer that the index fossil is found in.

To determine the size, shape, and behavior of the index fossil

To estimate the age of a rock layer using their position near an index fossil.

To identify how the tectonic plates around index fossils moved.

20.

1 point

Which best describes the type of tectonic movement that creates earthquakes?

Pressure builds between two plates.

Pressure is released when plates move.

Movement causes vibrations.

All of the above
