Which of these is solid?

• The outer core

• The inner core

The asthenosphere is located in which layer of the earth?

• In the crust

• In the inner core

• In the mantle

• In the outer core

What did Wegener use as evidence to support his hypothesis that the continents were drifting? Choose all that apply

• The continents look like they fit together like puzzle pieces.

• The fossils found on different continents matched up.

• The soil on different continents was the same color.

A long, undersea mountain chain where there is seafloor spreading is called a

• subduction zone

• mid-ocean ridge

• deep water trench

• fracture zone

The study of the alignment of magnetic minerals in rocks is called

• paleomagnetism

• hypnotism

• paleosols

• electromagnetism

What is the difference between normal and reversed polarity?

• Normal is when the magnetic fields point south and reversed is when the magnetic fields point north.

• Normal is when the magnetic fields point north and reversed is when the magnetic fields point south.

• Normal is when the magnetic fields point north and there is no such thing as reversed.

• Magnets always point to south now

Where is new crust being made?

• In the outer core

• In the mantle

• Deep within subduction zones

• At mid-ocean ridges
