Exam 9: Plate Tectonics, Earthquakes, and Volcanoes

Tsunamis are seismic waves that travel through the Earth's core.

Over the past 50 years, the levels of carbon dioxide in the atmosphere has been steadily increasing. Not discussed in this chapter?

Folds that usually form along broadly rounded ridges are known as: REWORD. They don't form along them they are broadly rounded ridges.

When lava rises to the surface through long fissures rather than a crater, the resulting formation is a broad, flat plain called a __________.

The type of collision that occurs when two lithospheric plates converge is determined primarily by plate thickness and :

Is there a connection between the distribution of earthquakes and the boundaries of the lithospheric plates? If so, please explain.

Explosive or voluminous eruptions may cause the volcano to collapse into the floor of the empty magma chamber below, producing a very large depression called a:

The figure below shows a stacked anticline and syncline. No reference in text to "stacked" anything in Ch9 text.

Referencing the figure below from the Jura Mountains, erosion in this ridge and valley system will expose the oldest rocks on the anticlinal ridges. the erosional pattern in a syncline will expose the oldest rocks in the middle.

As a result of the subduction of oceanic crust under a continental crust, magma is most likely to erupt from:

Hot-spot volcanoes can:

Small volcanoes that form when frothy magma is ejected under high pressure from a narrow vent is called a _________________.

The slower moving waves which are generated by an earthquake that usually create an up and down shaking motion are called ________________.

Mafic magma has a high amount of dissolved gases and is very explosive.

The largest earthquake in Japan's history, which occurred on March 11, 2011, had a magnitude of _________ based in the Richter scale. I'm not fond of this kind of memorization?

Which type of volcanic feature is most common in the circum-Pacific mountain belt around the Pacific Ocean basin?

A fold in rock forming a trough with the youngest? strata in the middle is known as a syncline.

A strike-slip fault is a fault in which the direction of movement is horizontal and parallel to the strike of the fault.

A fault type that is usually associated with compressional centers, where one block rides up over the other is known as a(n)__________ fault.
