Mass Movement: Soil Creep

A type of mass movement is Soil Creep. Soil Creep is the slowest of all types of mass movement. A soil creep happens when the ice melts and the soil is pulled down slope under the influence of gravity. Trees with curved trunks or roots and broke retaining walls and curved railroad tacks alos indicate a soil creep.

Fossil Fuels Journal Entry

Human consumption of fossil fuels is getting bad. We are using so much of fossil fuels to power our daily lives, that eventually we will run out. It is also effecting and polluting our earth and atmosphere. We need to find a safer alternative for these fossil fuels. Something that wouldn't pollute our atmosphere and we wouldn't run out of. The pollution from these fossil fuels is causing Global Warming which is causing a lot of other problems. We use fossil fuels for so many things. For example: gas, oil, electricity, ect. Since we use those things for almost everything of our daily lives, it's impacting the earth at an alarming rate. Pretty soon, there will be no fossil fuels left. What would we do then if we don't find an alternative energy source by then? In some countries, they use sugar cane or corn to power their vehicles. We don't have enough of those resources in America to power everything with sugar cane or corn, but I'm sure we'll find something eventually.

Coal

Coal is mostly made of carbon and hydrocarbons. It is a nonrenewable because it takes millions of years to be created. For millions of years, layers of dead plants on the bottom or the swamps was covered in water and dirt. That is what trapped the energy of the dead plants. The pressure and heat from the top layer helped form coal.

The Movie

3 Scientifically Accurate Things:
1. The ash covering everything
2. Acidic Water
3. Pyroclastic Flow

3 Scientifically Non-Accurate Things:
1. The hot spring becoming hot within seconds.
2. Them outrunning the Pyroclastic Flow
3. The water becoming acid that fast.

Fossils

This is a trace fossil. This is a trace fossil because it has animal prints in it. Trace fossils are when they have an imprint of animal trails.











This is an original remains fossil. It is an original remains fossil because it has the original remains of bone preserved in it. Original remains fossils are when tree sap trap the animal or bones and are preserved perfectly for millions of years.

Sequence in Layers Excersize

The youngest rock layer would be 3 because it is an intrusion so the other layers would have to have already been there. The next youngest layer would be 1 because the second intrusion doesn't go through it so it must have already been there and number 1 is at the top. Number 6 would be the next youngest because number 2 doesn't go through it and its the next layer below number 1. I think the next youngest layer would be layer number 2 because it's an intrusion that goes through the remaining layers of rock so it has to be younger. The second oldest layer of rock would be number 5 because it is above 4 if the vertical line were the fault is was even. The oldest rock layer would be number 4 because it would be at the bottom if the fault didn't happen and 2 also went through 4 before it went through 5.
