Half the coal used in the United States comes from this extraction process:

• strip mining

• open-pit mines

• tar fields

• oil rigs

• runoff from farms

Starting at the Earth’s surface and going towards the center of the Earth, what is the correct order of Earth’s layers that make up the Mantle?

• lithosphere, uppermost mantle, asthenosphere

• upmost mantle, asthenosphere, crust

• crust, uppermost mantle, asthenosphere

• crust, lithosphere, asthenosphere

• crust, uppermost mantle, lowermost mantle

The continental crust of the earth is __________ while the oceanic crust is __________.

• similar in composition to the outer core; thicker and lighter than the continental crust

• thicker and lighter than the oceanic crust; similar in composition to the mantle

• similar in composition to the mantle; thicker and lighter than the continental crust

• similar in composition to the outer core; similar in composition to the mantle

• thicker and lighter than the oceanic crust; similar in composition to the inner core

________ in the mantle and core make tectonic plates move.

• Conduction movements

• Earthquakes

• Radioactive decay

• Convection currents

• Conduction currents

"Subduction" is the process of a tectonic plate

• falling freely into the mantle

• being forced below another plate

• melting without moving

• sliding alongside another plate

• being sucked into the outer core

Which of the following statements regarding tectonic plate movement is true?

• Because of tectonic movements, Europe and Africa are drifting slowly toward the Americas.

• When continental plates collide with continental plates, both plates usually subside.

• When oceanic plates collide with continental plates, the continent usually rides up over the seafloor.

• Because of tectonic movements, India is moving away from China.

• When oceanic plates collide with continental plates, the oceanic plate usually rides up over the continental plate.

What causes the ring of fire?

• The subduction of Pacific plates under continental plates

• The drift of Europe and Africa away from the Americas

• The collision of two continental plates

• Mid-oceanic ridges

• Earthquakes

Which of the following would you not use to classify a rock you found on a recent hike?

• Chemical composition

• Physical properties

• Internal structure

• Mode of formation

• Color

Rock formed from magma extruded to the surface through volcanic vents is classified as

• Sedimentary

• Igneous

• Metamorphic

• Weathered rock

• Lava

The physical breakdown of a rock into smaller pieces is called

• The rock cycle.

• Sedimentation.

• Chemical weathering.

• Mechanical weathering.

• Abrasion.
