Examples of Mass Movement- Landslide


An example of mass movement is a land slide. Gravity is the main force for a landslide to occur, also it can be because of the slope of the land. The main reasons for a landslide are earthquakes, groundwater, volcanic eruptions and erosion. When a landslide happens it is usually made up of rock and dirt, and sometimes water depending on what started it in the first place.

December 15th journal entry

 Over the past couple of weeks I have been hearing all about this oil spill in the gulf. Along with all the things they are trying to do to stop the oil from going everywhere they are also trying to figure out who’s fault it is. Here is what I think, first of all it’s more then one persons jobs fault. There is the people who tested the cemented, that was supposed  to keep everything together, even though it failed 2 out of the 3 times they went along with it anyways and now look at where we are!! Also you could blame the actual workers who are working right with the machines. We all would think that they had been trained good and enough that they could tell when something was going wrong, but if you are going to blame the actual worker you would have to put a little blame on the people that trained them! Maybe they weren’t fit to be trainers? The list could go on and on. One person I think should not be blamed is the CEO of BP. It isn’t his fault that this happened he probably had no idea that the cement failed all her probably knew is that they were continuing to go along with this plan. So I think people need to stop blaming everything on him! As for how there punishment I think that they need to be fired or go through training to make sure this never happens again.

Coal: What is is made of?? How is it formed??

Coal is a fossil fuel and most of our coal was formed when most of the earth was covered in swamps, 300 million years ago. As plants and animals started to die there remains sank to the bottom of the swampy areas and they started to layer on top of each other this soon made a material called peat and after awhile all the layers started to get packed together more and it made coal!! Coal is mostly made of carbon, along with some sulfur, hydrogen, oxygen and nitrogen.
