Plate Tectonics Quiz Lesson 2 - Triangulation Method

What are the two layers of the Lithosphere? (check all that applies)

• crust

• upper mantle

• lower mantle

• inner core

• outer core

The plate tectonic theory suggests that the Earth's Lithosphere is divided into rigid sections that move as a unit called (a)   .

Which of the following are the kinds of crust?

• oceanic crust

• continental crust

• lithospheric crust

• pizza crust

The continental crust is thicker but less dense.

• True

• False

The oceanic crust is thicker and denser.

• True

• False

A series of vibrations (shaking) at the earth’s surface as a result from the movement of the lithospheric plates.

(a)  

It is the point on earth’s surface directly above the focus.

• epicenter

• fault

• focus

• earthquake

It is the point within the earth’s crust where the earthquakes begin.

• epicenter

• fault

• focus

• earthquake

A method that uses distance information from three seismic stations to locate the earthquake epicenter.

• triangulation method

• trial and error method

• scientific method

• none of these

In order to locate the epicenter of an earthquake, you need at least 3 data from how many seismic stations?

• 3

• 4

• 5

• 6
