Earth layers, Plate boundaries!

Our next section is on Earth Science, which includes: Plate tectonics, earthquakes, Layers of

the Earth, Volcanoes, and California Geology.

Create a cover with 4 pictures, 4 colors each (minimum), on the right side of a new open entry

based on our section.

Page 0! 8.1On the Left side (page 0), define these following terms: earthquake, focus, epicenter, fault, foreshock, aftershock

And answer these questions: 1-5.

REMEMBER to include the PAGE numbers where you found the vocabulary AND the answers to your questions.

READ the section together, do NOT use the glossary for the key terms. Read them in context.

Remember to get full credit, you must write the page number from the text book where you found the definitions of your words (NOT THE BACK!) and where you found your answers to the ?’s.

C.O. – Students will understand the causes and effects of earthquakes resulting from plate tectonics.

L.O. – Students will work together to answer questions and write notes about Earthquakes.

C.O. – Students will explore earthquake effects on the crust of the earth and the rock layers associated with it.L.O. – Students will work together in groups, reading together and building a fault model. Then they will answer questions based on their observations of the effects of their model moving in different ways.

The Science of Predicting Earthquakes

Even though we cannot predict earthquakes, we have learned a lot from studying them. Like…

- how to pinpoint the locations of earthquakes

- how to accurately measure their size

- how to build structures that can withstand them.

6. What 2 plates come in contact with each other in California at the San Andreas fault?

EARTHQUAKES!

* Define Earthquake More than 30,000 earthquakes occur every year!

200-300 in California everyday!

EARTHQUAKES are the sudden shaking of the ground caused by the release of energy of plates slipping past each other.

The FOCUS of an earthquake is the point IN the Earth where the earthquake actually started.

The EPICENTER of an earthquake is the point on the surface of the Earth, where the EQ occurred.

http://www.data.scec.org/recenteqs/

You can STAND on the epicenter.

You CANNOT stand on the focus

EARTHQUAKES!

* Define Earthquake

FAULTS are fractures in the Earth where movement of plates has occurred.

The San Andreas Fault is the most famous fault in North America.

8.1 Quiz!Please get out your homework calendar.

Study your VOCAB words from your 8.1 homework.

Remember the flashcards.

You should also be able to describe the 3 different types of FAULT movement.

8.1 Quiz!Please review your vocab and your faults homework paper to prepare for the quiz!

EARTHQUAKES! Draw this on the top half of Page 2!

At a fault there is a hanging wall and footwall.

In a “normal” fault, the hanging wall slides DOWN the footwall.

In a “reverse” fault, the hanging wall pushes UP

In a strike-slip fault, they slide past each other.

EARTHQUAKES!

* What are the causes of earthquakes?

As faults interact with each other at a boundary, it causes rocks to “bend” and store energy.

At some point the rock is no longer able to sustain that energy and a “failure” occurs where the rock breaks or slips at the weakest point.

Think of holding a door handle while someone is pushing/pulling and you suddenly let go…

EARTHQUAKES!

Standard ESS2-3: Develop a model based on evidence of Earth’s interior to describe the cycling of matter by thermal convection.


EARTHQUAKES!

* What are aftershocks and foreshocks?

Aftershocks are the movements of the Earth that follow AFTER a major earthquake.

Foreshocks often come before a major earthquake, days, even years before a major quake.

So how do we measure them?

So how do we measure them?

EARTHQUAKES! On the bottom half of page 2, write down 10 observations (in bullet points) that have to do with earthquake measurements from the video. They could be about the instruments used, examples of large earthquakes (and their measurement), damage caused, or HOW we measure them.

EARTHQUAKES!

* Describe HOW a seismograph works.

We measure earthquakes with a SEISMOGRAPH

Because earthquakes generate seismic waves, they can be measured by a seismograph

A seismograph is implanted in the ground and sends digital signals to a computer that measures its MAGNITUDE!

EARTHQUAKES!

• Describe HOW a seismograph works.

• What type of waves are produced by Earthquakes? DRAW AN EXAMPLE OF EACH.

Earthquakes are simply the sudden shaking of the ground.

This shaking produces SEISMIC waves by energy being released in all directions. There are 2 types of waves: Body and Surface waves.

1. Body Waves (travel through Earth’s interior)

A. P Waves (Primary Waves)

a. P waves are LONGITUDINAL. Travel through anything and are the fastest.

b. they arrive at seismographs first.

Draw this on page 6





B. S Waves (Secondary or Shear Waves)

a. S Waves are TRANSVERSE waves.

b. They do NOT travel through liquids.

Draw this on page 6 under your P wave Picture








2. Surface Waves (travel on Earth’s surface)

A. Rayleigh Waves (circular motion), like the ocean

a. Slower than p and s waves








2. Surface Waves (travel on Earth’s surface)

A. Rayleigh Waves (circular motion), like the ocean


b. Cause major surface damage

B. Love Waves (side to side motion)


b. Cause moderate surface damage.


• Seismic waves produce MOVEMENT on the earth.

• Seismographs are INSTRUMENTS used to measure these waves

• There are 2 scales we use to “measure” earthquakes.
