Rock and Layers of the Earth

What do the Andes mountains and the Appalachians mountains have in common?

• They formed at tectonic plate boundaries.

• The formed in the middle of the ocean.

• They are located in North America.

• They are the same size.

What is a result of the heating and cooling of Earth's mantle?

• conduction currents that move the lithospheric plates

• on currents that move the lithospheric plates

• conduction currents that move the plates on the outer core

• convection currents that move the plates on the outer core

Which statement correctly describes the outer core?

• Composed primarily of magnesium and iron particles, the outer core is the middle layer of Earth, and contains the most heat.

• Composed primarily of silica particles, the outer core is the outermost layer of Earth, and varies in temperature and thickness.

• Composed primarily of iron and nickel, the outer core is a liquid layer that rotates around the inner core, and is responsible for Earth's magnetic field.

• Composed primarily of magnesium, oxygen, aluminum, and silicon, the outer core is a dense, solid layer, and is responsible for the motion of Earth's plates.

This picture best represents_________.

• convection

• a convergent boundary

• conduction

• a transform boundary

The earth's mantel is made up of which two parts?

• Lithosphere

• Asthenosphere

• Mesosphere

• Outer core

• Inner core

Which statement describes layers 1 and 2?

• Layer 1 is the outer core and is not dense. Layer 2 is the inner core and is very dense.

• Layer 1 is the inner core and is not hot. Layer 2 is the outer core and is very hot.

• Layer 1 is the outer core and is liquid. Layer 2 is the inner core and is solid.

• Layer 1 is the inner core and is solid. Layer 2 is the outer core and is liquid.
