Earth's Interior

We are now studying the inside of the Earth in class.  As you are finding out, it is not easy to figure out what the inside of the Earth looks like but scientists believe, after a lot of hard work, that they have figured it out! 

So what???

How does knowing the structure of the inside of the Earth help us to understand things happening on the surface? 

Make sure to write at least 6 sentences in your explanation about why it is important.  This is due by the time you come to class on Thursday.  Happy Blogging!
