This is my favorite week of class. I do love weather and climate, and rivers and glaciers are pretty cool. 
But in my opinion, the coolest, most amazing thing in physical geography is volcanoes and earthquakes. 
The heat energy stored up inside our planet is phenomenal! Check out this video I took on a visit to Lassen Volcanic park this summer: 
You are looking a mud pool in the ground that is boiling and releasing noxous sulphur gas.  
Lassen last erupted in the early 20th century. However there is still a lot of heat just under the earth, 
enough to make these mud pools boil and steam. 
The same energy that causes volcanoes also powers the movement of the earth’s tectonic plates which cause the small frequent 
earthquakes as well as the major destructive ones that hit our planet.
This week you have two things due, lab 4 and the data discussion for the weather and climate project 
which takes place in the discussion forum. You should also be working the write up for the weather and climate project, 
because it is due next week. If you have any questions, just let me know.
