Lesson 5 Earthquakes

Lesson 5 Earthquakes

Make sure you have a notebook/pieces of paper and pens/pencils for an activity today.

Unit 3 test will happen on March 16. Midterm report cards are due March 19.

Multiple Select

Which of the following are true about earthquakes?

• They result from a release of matter and particles

• They're mainly associated with one type of fault

• They result from a release of energy

• When rock bends, it never returns to its original shape

• When rock bends it is able to return to its original shape

Multiple Choice

Which of the following is correct about the focus and epicenter of an earthquake?

• A focus (or hypocenter) is the place on the surface above the epicenter, where faulting first occurs.

• During an earthquake, waves move from far away towards the hypocenter/focus

• An epicenter is located above the focus (hypocenter)

• An earthquake's epicenter is unable to be determined exactly.

Multiple Choice

In which order to seismic waves arrive:

• L, S, P, R

• S, P, L, R

• P, S, L R

• S, L, P, R

• P, S, R, L

Fill in the Blanks

L-wave motion is most similar to which other wave's motion:

Fill in the Blanks

The longer it takes a P-wave to be recorded by a seismograph, the

(closer/further) it is from the epicenter.

Multiple Choice

On a seismogram, which waves will have a higher amplitude (height):

• surface waves

• body waves

• both types have similar amplitudes

• it depends on the earthquake

Multiple Select

Select all the locations in which an earthquake can occur:

• Ring of Fire

• Convergent boundary between two continental plates (Himalayas)

• Along Mid-Ocean Ridges

• With transform plate boundaries

• Along dormant volcanoes

Multiple Choice

Aside from the shaking itself, which other hazard could cause the foundation of a building to fail?

• Landslides

• Liquefaction

• Tsunamis

• Fire

Multiple Choice

Could a tsunami occurs if the San Andreas fault experiences an earthquake of magnitude 7 or above?

• Yes

• No

Poll

How comfortable do you feel with the lesson?

• It was difficult to understand and might need some help.

• It was a bit difficult, and hopefully next week's review helps.

• It was somewhat easy, but I think some review might help me better understand it.

• It was fairly easy to understand it

• I totally feel confident with this lesson
