Classwork (12/3): Intro to Seismic Waves

Hello and welcome to your classwork for Wednesday 12/3 :) Draw me a picture of anything you want to begin

BEFORE WE BEGIN: How deep do you think we have ever DUG into the Earth? How far down into the earth do you think we've gone?

Mark a dot or a line in the picture to the right. Take note of the distances on the left side!

DON'T LOOK IT UP! - This is a guess!!

BEFORE WE BEGIN: How do you think scientists study the interior of the Earth? In other words, how do we get information about what the inside of the Earth is made of? (IN YOUR OWN WORDS- DONT LOOK IT UP!)

Look at the image provided (click the + to make it bigger). We use​ (a)   to study the interior of the Earth. Scientists study the waves of​ (b)   that come from​ (c)   to study ​ (d)  

• earthquakes
• energy
