Which of the following is not one of the earth's interior concentric zones?

1. 10 Which of the following is not one of the earth's interior concentric zones? • the asthenosphere. • the crust. • the mantle. • the core. • None of these answers.

2. 10 The earth zone with the most volume and mass is the • lithosphere. • core. • crust. • mantle. • oceanic crust.

3. 10 The asthenosphere is • the outer atmosphere. • the inner core of earth. • a plastic region in the crust. • a plastic region in the mantle. • a solid region in the mantle.

4. 10 The majority of earthquakes and volcanoes occur • in the interior of continents. • on oceanic islands. • along the edge of continents. • in the open ocean. • In the U.S.

5. 10 The theory of plate tectonics explains • the occurrence of earthquakes. • the occurrence of volcanoes. • movement of earth's plates. • the occurrence of mountains. • All of these answers.

6. 10 A ____ is not one of the three types of boundaries between lithospheric plates. • transform fault • mantle fault • convergent plate boundary • divergent plate boundary • lithosphere fault

7. 10 Tectonic plates move apart in opposite directions at a(an) • divergent plate boundary. • transform fault. • convergent plate boundary. • subduction zone. • mantle fault.

8. 10 Tectonic plates move in opposite but parallel directions along a fault at a(an) • divergent plate boundary. • transform fault. • convergent plate boundary. • subduction zone. • mantle fault.

9. 10 The movement of lithospheric plates is significant because it • explains the formation of waterfalls and river canyons. • predicts where certain natural hazards are likely to be found. • explains formation of ocean currents. • predicts where endangered species might be found. • explains the formation of weather.

10. 10 The energy sources primarily responsible for earth's external geological processes are • energy from the sun and magnetism. • energy from the sun and gravity. • energy from the sun and heat from earth's interior. • gravity and magnetism. • only gravity.

11. 10 An earthquake is most directly caused by • the creation of a fault (fracture in rock) or shifting along an existing fault. • a change in ocean currents. • dumping of toxic wastes. • comets crashing into earth. • mining.
