Earthquake and Volcano Review - Hnrs 175

_______, which are responsible for moving the tectonic plates, can be found _______.

• Magnetic fields; in the outer core of the earth

• Convection currents; in the asthenosphere and upper mantle

• Wind currents; in the 0º - 30º latitude range

• Convection currents; in the inner core of the earth

How do the two types of plates on our planet compare?

• Oceanic plates are generally thinner and more dense than continental plates.

• Continental plates are generally thicker and more dense than oceanic plates.

• Continental plates are generally thinner and more dense than oceanic plates.

• There is no difference in density between oceanic and continental plates, but oceanic plates are usually thicker.

• There is no difference in thickness between oceanic and continental plates, but continental plates are usually denser.

The type of plate boundary seen here is:

• diverging

• converging

• transform

• strike-slip

• reverse

The type of landforms we might expect at a plate boundary like this include:

• mountains

• volcanoes

• ocean trench

• all of these

A good real-life example of a landform that came from a plate boundary like the one seen in the picture would be:

• Mariana trench

• Cascade Mountain range

• Himalayan Mountain range

• Aleutian Island chain

At a transform plate boundary, one would expect:

• volcanoes

• mountains

• island arcs

• earthquakes

The point on the earth's surface where the most violent shaking is felt during an earthquake is:

• the focus

• the epicenter

• the hypocenter

• the pivot point

The building in this picture is likely experiencing what effect caused by an earthquake?

• ground breaking

• liquefaction

• landslide

• tsunami

_____ arrive first after an earthquake has happened, and ______ are more violent.

• P-waves; p-waves

• P-waves; s-waves

• S-waves; p-waves

• S-waves; s-waves

Where can volcanoes occur?

• along subduction zones

• along divergent plate boundaries

• along convergent plate boundaries

• at "hot spots" in the mantle

• all of these
