Earth Layers and Plate Tectonics

This solid layer of the earth is made of mostly iron and nickel.

• Crust

• Inner Core

• Mantle

• Outer Core

What is the earth's outermost layer?

• Crust

• Lithosphere

• Mantle

• Outer Core

What is the earth's only liquid layer?

• Asthenosphere

• Inner Core

• Mantle

• Outer Core

The layers of Earth are:

• hydrosphere, atmosphere, troposphere, outer core and inner core

• stratosphere, ionosphere, troposphere, outer core and inner core

• crust, mantle, outer core and inner core

• tectonic plates, faults, lithosphere and core

• lithospheres

• synclines

• anticlines

• faults

Subduction zones occur on Earth where dense oceanic crust dives under more buoyant continental crust. These boundaries are characterized by a deep ocean trench next to a high continental mountain range, large numbers of earthquakes and volcanoes. All of this is further evidence for the

• big bang theory.

• theory of plate tectonics.

• origin of the species.

• theory of natural selection.

Observe this diagram of a plate boundary. One statement BEST describes what is happening. It is that

• the oceanic crust is melting.

• the denser ceanic crust is subducting under the less dense oceanic crust

• volcanic islands are forming.

• the tectonic plates are moving away from each other.

Where would sea floor spreading most likely occur?

• At convergent boundaries (oceanic vs. oceanic)

• At convergent boundaries (oceanic vs. continental)

• At divergent plate boundaries (oceanic vs. oceanic)

• At transform plate boundaries
