Earth's Interior and Plate Tectonics

When comparing the lithosphere to the asthenosphere, which statement is correct?

• The asthenosphere is a thin layer that sits on top of the lithosphere.

• The asthenosphere is part of the crust, and the lithosphere is part of the mantle.

• The lithosphere is brittle and rigid, and the asthenosphere is plastic-like and flowing.

• The lithosphere is a layer of flowing hot magma that supports the solid thin layer of the asthenosphere.

Which layer of the Earth is described as "brittle and rigid"?

• asthenosphere

• inner core

• lithosphere

• outer core

Which is true about the location of the asthenosphere?

• It is located just above the lithosphere.

• It is located in the lower part of the mantle.

• It is located in the upper part of the mantle.

• It is located in the inner core.

Which is defined as the solid part of the Earth's surface?

• atmosphere

• hydrosphere

• lithosphere

• troposphere

Which part of the Earth's interior is liquid?

• crust

• inner core

• mantle

• outer core

When parts of the upper mantle collide with each other, the force causes changes on the surface like volcanoes and fractures. Why does the collision not impact the asthenosphere?

• The asthenosphere is rigid and brittle.

• The asthenosphere is rigid and flowing.

• The asthenosphere is plastic and flowing.

• The asthenosphere is plastic and brittle.
