6.E.2.1 Layers of the Earth Test Review

What are the contents of Earth’s outer layer?

• gases and water

• the mantle and landmasses

• the atmosphere and the oceans

• continental crust and oceanic crust

What evidence provides the most information to geologists concerning the structure of the Earth's interior?

• fossil remains found in caves

• observations of other planets

• rock samples and seismic waves

• temperature measurements in deep mines

Which explanation provides the best scientific reason for the ordered arrangement of Earth’s layers?

• The densest elements sink toward the center of Earth, while the least dense elements rise toward the surface of Earth.

• Iron is magnetic, so the iron in the core binds together and is unable to move to other layers of Earth.

• The core is the oldest material on Earth, and newer material is always found on top of older material.

• Some layers of Earth are solid, while others are liquid; therefore, they do not mix or move easily.

• tectonic plates

• mesosphere

• continents

• crust

Which description is true of Earth’s four layers?

• They all have an equal thickness.

• They all have the same physical properties.

• They all undergo the same physical changes.

• They all are defined by a unique chemical composition.

Which occurs as one goes deeper into Earth’s interior?
