Earth's Interior / Plate Tectonics 1

Humans have inferred the structure of Earth's interior by...

• Analyzing the behavior of earthquake waves

• Analyzing volcanic eruptions

• Traveling toward the center of the Earth

• Analyzing the interiors of other planets

The lithosphere is made of which two smaller layers? (USE PAGE 10 OF ESRT)

• Outer core and inner core

• Asthenosphere and stiffer mantle

• Crust and rigid mantle

• Hydrosphere and troposphere

In which layer of the Earth might you find rock with an average density of 4.0 g/cm3? (USE PAGE 10 OF ESRT)

• Asthenosphere

• Stiffer Mantle

• Outer Core 

• Inner Core

Which layer of the Earth is composed of liquid iron and nickel? (Use page 10 of the ESRT)

• Asthenosphere

• Stiffer Mantle

• Outer Core

• Inner Core

An interior temperature of 2,000C would be found in which layer? (Use page 10 of the ESRT)

• Asthenosphere

• Stiffer Mantle

• Outer Core

• Inner Core

At a depth of 5,000 km, what is the inferred pressure? (Use page 10 of the ESRT)

• 6,200 atmospheres

• 1 million atmospheres

• 2 million atmospheres

• 3 million atmospheres

Which of the following is NOT evidence for the theory of continental drift?

• Continental crust is less dense than oceanic crust

• There are similar fossils found on different landmasses today

• There are similar mountain ranges and rock layers found on different landmasses today

• The present landmasses appear to fit together
