Plate tectonics and Continental Drift

The Lithosphere is composed of the Earth's Crust and the Upper Mantle.

• True

• False

Answer explanation

True the Lithosphere is composed of the Earth's crust and the upper mantle. The Lithosphere rests on the Asthenosphere

The Lithosphere rests directly on top of the

• Asthenosphere

• Earth's Crust

• Outer Core

• Inner Core

Answer explanation

The Asthenosphere is a layer under the Lithosphere made of pliable rock material that provides the tectonic plates a surface to move on.

In 1912 Alfred Wegener introduced the _______________ Hypothesis.

• Plate Tectonics

• Convection Currents

• Continental Drift

• Big Bang Theory

Answer explanation

In 1912 Alfred Wegener proposed the Continental Drift hypothesis to explain how the continents have moved from one location to another over time.

The Continental Drift Hypothesis is supported by the discovery of fossils of the exact same type and same time period found on different unconnected continents.

• False

The ideas of continental drift and seafloor spreading were put together to create the Theory of ______, which suggest that the crust is broken into sections that move in different directions.

• Convergent boundaries

• Plate Tectonics

• Continent theory

Answer explanation

The Theory of Plate Tectonics states the continents and ocean basins are embedded in the lithospheric plates. When the plates move so do the continents.

What type of plate boundary is pictured?

• Convergent

• Divergent

• Transform

• Ripping

Answer explanation

Convergent collision boundaries push toward each other causing the two boundaries to collide and weld into a single larger continent. This is a Continental-Continental Convergent boundary. This type of boundary collision usually results in the formation of mountains

What type of plate boundary is pictured?

• Convergent

• Divergent

• Transform

• Ripping

Answer explanation

Convergent subduction boundaries push toward each other with on plate subducting under the other. This is a Oceanic-Continental Convergent boundary. The denser Oceanic plate will subduct forming a deep sea trench and a mountain chain and volcanoes form on the overriding continental plate.

An Oceanic-Oceanic Convergent subduction boundary will create a Deep Sea Trench and a volcanic island arc

The Mariana Trench in the Pacific Ocean is 36,160 feet below sea level. This deep oceanic trench is caused by --

• excessive boat traffic disrupting the normal sedimentation process

• two Oceanic tectonic plates colliding and one plunging below the other (convergent boundary)

• Two tectonic plates sliding past each other (transform boundary)

Answer explanation

The Mariana Trench was created by an

Oceanic-Oceanic Convergent boundary
