Global Temperature Graph

1. The horizontal scale is by 20 years. It is showing the years 1880-2000.
2. The vertical axis is showing the temperature anomaly. It goes up by .2. The total range is -.4 to .6.
3. I can tell that it came from a school website on their assignments.

Questions

• 1 - What do you think the global average temperature is?  This means the average for everywhere on Earth, day and night, for an entire year.  Explain why you answered what you did.
• I think it would be 50 degrees because for the most part, half the areas of the earth are really really cold and the other half is really really hot or some areas are in between.
• 2 - People are often talking about "global warming."  How much do you think the average global temperature has increased in the past 100 years?  Do you think that this is a lot?
• I think it has increased around 20 degrees. I think this is a lot because 20 degrees can make a big difference. 
• 3 - What do you think is the hottest the Earth has ever been? (since there has been an atmosphere?)  How about the coldest the Earth has ever been?  Explain why you answered what you did.
• I think the hottest it has ever been is around 150 because in some places the earth is realllllyyyyyyyy hot. I think the coldest it has ever been is around -50 or -50 degrees because it's like that in Antartica.
• 4 - Are you concerned about "global warming?"  Why or why not?
• Yes, because the ice caps are melting which is causing the ocean to rise which means some places will be underwater.

Question 4

The amount of rainfall shows how it can affect the types of soil because of the wet or dryness. In forest soils, the soil is shallow. But in grassland soils, the soil is much deeper. This is because the climate is very hot in the grasslands and doesn't have much rain. So, the rocks weather faster. In the forest lands, there is much more rain and isn't hot year round so it doesn't weather down as easily.

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.
