Earth's Interior

Why do geologists drill through the oceanic crust in their attempt to reach the mantle/

• It is softer than the continental crust.

• It is thinner than the continental crust.

• It is younger than the continental crust.

• It is less dense than the continental crust.

Which sequence shows the order of the Earth's interior from surface to center?

• crust, outer core, mantle, inner core

• crust, mantle, inner core, outer core

• inner core, outer core, mantle, crust

• crust, mantle outer core, inner core

What is true about the Earth's crust?

• It is uniform in thickness.

• It floats above a layer of hot magma.

• It consists mostly of iron and nickel.

• It has a higher density than the core.

Which statement is true as the depth within the Earth's interior increases?

• The density, temperature and pressure of the Earth's interior increases.

• The density, temperature and pressure of the Earth's interior decreases.

• The density, temperature of the Earth's interior increase and the pressure decreases.

• The density and temperature of the Earth's interior decrease, and the pressure increases.

How does the continental crust compare to the oceanic crust?

• The continental crust is thinner and made mainly of granite.

• The continental crust is thicker and made mainly of basalt.

• The oceanic crust is thicker and made of granite.

• The oceanic crust is thinner and made of basalt.

A student is studying the features of Earth's core and reads that it is the most dense layer of Earth. What other feature is true of this layer?

• It has a solid inner core.

• It is the thickest layer of Earth.

• It is made of silicon and oxygen.

• Its top portion is called asthenosphere.

How are the lithosphere and the asthenosphere similar?

• They are both part of the crust.

• They are both part of the mantle.

• They both have the same thickness.

• They both have the same physical properties.
