Earth's Interior Quiz

Which layer of Earth is solid and why?

• The inner core is liquid because of movement of the outer core.

• The inner core is solid because of the freezing temperatures.

• The inner core is solid because of the extreme pressure from the other layers.

What is the thinnest layer of the Earth?

• Mantle

• inner core

• outer core

• crust

Analyze the data below.

The continental crust is more than 60 km thick in mountainous regions. The oceanic crust is less than 5 km thick under some parts of the ocean.

Choose the statement that is TRUE.

• Oceanic crust is thinner than Continental Crust and denser than Continental Crust

• Continential crust is thinner than OceanicCrust and denser than Oceanic Crust.

How do scientists know the Earth has layers?

• Drilling into the mantle

• Volcanoes

• Seismic waves data

• ocean waves

There is a pattern to Earth's interior layers. It is one of ...

• solids and liquids

• magnetic and nonmagnetic

• colors, specifically black and red

• gas and plasma

This layer of the Earth makes up the majority of the Earth's volume and is where convection currents happen in the upper section.

• Crust

• Mantle

• Outer Core

• Inner Core

• P waves
• S waves
• Radio Waves
• X rays

Earth's radiant interior heat causes convection currents in the mantle, and as a result this flow of energy causes tectonic plates to move.

• true

• false

If S waves only travel through solids, why is there no evidence of s waves in the core?

• Earth's outer core is liquid.

• Earth's inner core is liquid.

• S waves can travel through solids and liquids, so this is a trick question.

Why does Earth experience earthquakes?

• The lower mantle sloshes causing all the layers above it to move rapidly.

• Convection Currents occur in the Inner Core.

• Tectonic plates move.

• The asthenosphere is solid.
