Earth's Layers and Plate Tectonics

The lithosphere includes which layers of Earth?

• The lower mantle and the outer core

• The inner and outer core

• The crust and upper mantle

• The upper mantle and lower mantle

Before the theory of plate tectonics came to be,

• Scientists drilled to the center of the Earth to see what was happening.

• Scientists discovered seafloor spreading which lead to the concept of continental drift.

• Scientists dated fossils from different animals.

• scientists measured ice caps to see if they decreased in size.

Which best describes Earths outer core?

• It is located between the lower mantle and the inner core.

• It is solid iron

• It is liquid water

• It is hotter than the inner core.

How do scientists study Earths structure?

• Drilling to the center of the Earth.

• Using seismic waves to map and collect data.

• By following a lava flow to a volcano.

How do convection currents effect the Earth?

• They make the Earth hot.

• They drive plate tectonics

• They create the magnet layer.

• They provide weather for the breakdown of rock.

How do scientist study the interior of the earth?

• Drill down into the Earths core and make observations

• Scientists study the movement of seismic waves below the Earths surface.

• Using satellite imagery

• By watching the plates move.

The theory of plate tectonics _________________.

• states that the exact movement of a plate can be calculated.

• explains why the outer layers of Earth move and change.

• explains that the Eurasian plate will return to Pangea.

• states that matter can not be created of destroyed.
