Layers of Earth and Plate Tectonics

What is the main method of heat transfer from the core to the crust of Earth?

• conduction

• convection

• insulation

• radiation

This layer of Earth is thought to be a solid, iron-rich zone.

• mantle

• outer core

• inner core

• lithosphere

In the diagram of the ocean basin, where is the oldest oceanic crust found?

• A

• B

• C

• D

What process does the image represent?

• the creation of rift valleys by the divergence of tectonic plates

• the formation of an oceanic trench by the subduction of tectonic plates

• the convergence of tectonic plates, resulting in the creation of fold mountains

• the spreading of new crust created by volcanic activity near a mid-oceanic ridge

Find the Aleutian trench that is circled on the map seen here. This area is the site where two tectonic plates meet. Islands have formed due to volcanic activity; tsunamis are a reasonable occurrence; there is a great trench here, the Aleutian Trench. What is this region called where the heavier, more dense crust sinks beneath the lighter crust.

• subduction zone

• divergent oceanic-continental plate boundary

• convergent continental-continental plate boundary

• divergent oceanic-oceanic plate boundary

What do scientists call the large supercontinent that once existed?

• Eurasia

• Pangea

• Panamerica

• Ring of Fire

All of the following are evidence used to support the theory of continental drift EXCEPT

• global warming of the Earth’s atmosphere

• deposits from glaciers on warmer continents

• the same fossils found on different continent

• matching landforms found on different continents

What type of event will occur at this boundary?

• Earthquake
• Volcano Eruption
• Tornado
• Mountain Building

How is it possible for new crust to be formed without increasing the surface area of the Earth?

• Crust is destroyed at the same time it is created
• New crust is underwater where it sinks
• New crust breaks more easily than old crust
