ES Unit 6a Plate Tectonics Test Review 2023

New crust is made at a divergent plate boundary.  Crust is destroyed at a convergent boundary with a subduction zone.  How does this support the Law of Conservation of Mass?

• crust is made twice as fast as its destroyed

• crust is destroyed faster than crust is created

• crust is created and destroyed in equal amounts, thus conserving mass

• crust is getting bigger due to divergent boundaries.

When looking at a topographic map, how do you know which side of a hill has the steepest slope?

• Contour lines are far apart

• Contour lines are close together

• Contour profile lines are parallel

• Contour interval is small

Which is most likely to be on a plate boundary and most subject to volcanoes and earthquakes?

• West coast of South America

• Central part of Africa

• Central Asia

• Central Australia

Virginia Beach is located well away from a plate boundary.  Which of these is LEAST likely to occur in the Coastal Plain?  (select all that apply)

• Crustal uplift and rock deformation

• Erosion and deposition

• Rifting and intrusion

• Subduction and metamorphism

In which layer of the Earth would you find the highest density?

• crust

• mantle

• inner core

• outer core

An earthquake shear wave generally travels faster as the wave moves deeper into Earth's interior because greater depths have

• less confining pressure

• greater rock temperatures

• lower melting points

• greater rock density

Which of the following provide evidence for the plate-tectonics theory?  (select all that apply)

• matching magnetic patterns on each side of a mid-ocean ridge to the geomagnetic reversal time scale

• discovering that ages and types of rocks in the coastal regions of widely separated areas match closely

• similar fossils on different continents

• suggesting that continents plow through the crust

Which of the following best describes the composition of ocean crust?

• relatively thin, young, and dense

• relatively thick, young, and very dense

• relatively thick, old, and less dense

• relatively thin, old, and very dense

Where in Virginia would you find most of the state’s coal resources?

• Coastal Plain

• Appalachian Plateau

• Blue Ridge

• Valley and Ridge

Which of the following is formed at a convergent plate boundary?

• a continent

• mid-ocean ridge

• Hawaiian Islands

• deep ocean trench
