The primary cause of continental drift, earthquakes, and volcanic eruptions is S6E5f

• the rotation of Earth on its axis

• heat from the Sun warming Earth

• the gradual sinking of Earth’s crust

• lithospheric plates beneath Earth’s crust

Alfred Wegner’s Theory of Continental Drift was not well accepted because he couldn’t say what force could be big enough to move continents. Current theories explain this movement with

. S6E5a

• convection currents in the mantle

• hot spots forming under continents

• subduction zones at continental margins

• magnetic reversals of the north and south poles

Imagine you could drill a hole all the way to the center of the Earth. Assuming that you drill the same speed the entire way, which layer would take the longest to drill through?

S6E5a

• Crust

• Mantle

• Outer Core

• Inner Core

A student is making a diagram of Earth’s layers. How should the temperature be labeled on the different layers? S6E5a

• The crust would be hotter than the mantle.

• The outer core would be hotter than the mantle.

• The crust would be hotter than the inner core.

• The outer core would be hotter than the inner core.

The mountain shown is composed of deformed sedimentary layers. They are located near a tectonic plate boundary and are still increasing in elevation due to — S6E5f

• colliding tectonic plates

• subduction of a tectonic plate

• seafloor spreading of tectonic plates

• transform faulting of a tectonic plate

The most common cause of earthquakes is — S6E5f

• the sinking of the ocean floor

• movements in the Earth’s crust

• giant tidal waves called tsunamis

• unequal heating of the atmosphere

A student is making a diagram of Earth’s layers. How should his diagram be labeled to show the difference between Earth’s core and Earth’s crust? S6E5a

• The core should be labeled as denser and hotter than the crust.

• The core should be labeled as denser and colder than the crust.

• The core should be labeled as denser than the crust but with the same temperature as the crust.

• The core should be labeled as the same density as the crust but with a hotter temperature than the crust.

When Joe saw the Rocky Mountains for the first time, he exclaimed, "These mountains are much younger than ours back East!" Explain which feature supports his conclusion that the Rockies were relatively young mountains. S6E5f

• · The mountains back east have flatter tops and have been eroded longer, so

  they are older.

• · Difference between old mountains and young mountains is the level of erosion within the entire mountain range- the Rocky Mountains are young because they are rugged, with very little signs of erosion.

• · Rocky Mountains resulted from compressional folding and high angle upfaulting that eroded into hogback ridges.

• · Rocky Mountains have attributes of high elevations with many peaks exceeding 13,000 feet

• Rocky Mountains known as the "Rockies" are part of a great mountain belt that stretches down the western sides of North and South America. Rocky Mountains have attributes of high elevations with many peaks exceeding 13,000 feet. Rocky Mountains resulted from compressional folding and high angle upfaulting that eroded into hogback ridges. Difference between old mountains and young mountains is the level of erosion within the entire mountain range- the Rocky Mountains are young because they are rugged, with very little signs of erosion. These mountains are still uplifted due to tectonic forces. The mountains back east have flatter tops and have been eroded longer, so

  they are older.
