This is an article about the tectonic plates that make up the crust of our planet.

This was a very informative website about tectonic plates. It talked about where plates are found and boundaries made by these plates.

This was a very good article about the movements of tectonic plates. One of the most interesting facts that I had learned from reading the article was that the tectonic plates make up earths outer shell called the lithosphere. There were also many different things that I didn't know about such as that if the plates keep diverging in the Great Rift Valley in Africa, millions of years from now, eastern Africa will split apart from the continent creating a new continent. the three different types of Tectonic Boundaries are called convergent, divergent, and transform.

This is a website about stromatolites.

This is a good website on stromatolites and the history behind them.

This is a great website on stromatolites and its what we learned. Great job!

This websites provides excellent proof of the fact that global warming is real. In the last 650,000 years CO2 levels did not go over 300 ppm. However in recent times the ppm has sky rocketed to 390 ppm. I find it is also frightening that ten of the hottest years occurred in the last 12 years. Coldest records are not being reported as often as they used to be. The top 700 meters of the ocen has rose a frightening .3 degrees Fahrenheit seance 1969. The acidity of the ocean has also risen by 30%. This website backs up my ideas on climate change. I believe and so does NASA that global warming is happening now.

This website is very detailed, it has a graph and excellent proof of global warming.

This link show you that global warming does make an effect on the earth. It tells you lots of good information. I was surprised that the earth has had its hottest temperatures in the last 12 years! There has been no coldest records in a long time.

This is a really good website to learn about Earth overall in general. It gives the information about some of earths main tectonic plates(which is color coated so you know which one is which, a size comparison to the moon, which can involve a little bit of math. It also talks about the terrain/surface, weather and climate, and atmosphere.

By the way I posted this website

This is a cool website about life on earth, mass extinctions, ancient earth habitats, etc.

This website describes what kind of research NCAR is doing and what they have been finding on the issue of climate change. It goes into detail about what the climate was like in the past, the climate in the future, and what the causes of climate change really is. The climate has been changing ever since the Earth began, even before humans, but modern weather measurements only go back to 100-150 years ago. We don't know what the climate of the Earth really was in the prehistoric times. The Earth is getting warmer. According to tests, the Earth's surface temperature has risen more than 1.33 degrees fahrenheit since the late 1800s. There is more about what is causing the climate to change and what the climate will look like in the future.

The region of Earth receiving the Sun's direct rays is the equator. Here, air is heated and rises, leaving low pressure areas behind. Moving to about thirty degrees north and south of the equator, the warm air from the equator begins to cool and sink. This is a good website to learn about the Earth wind patterns, like some half of the advisories today had learned in the video.

This is help full to know more about Colorado earthquake history.

I never knew Colorado had any earthquakes, but the largest one was a 6.6!

This was helpful to learn about the history of Eathquakes in Colorad. Didn't know that Colorado ecer had a earth quake history let aline actually have a minor earth quake in the 1800. Even though I didn't learn about ts in my class, other clsses had probablly learned abiut it.

Q and A with climate change facts! Good to quiz yourself with:) my favorite is: In the past, has Earth been warmer than it is today? If so, does that mean we shouldn't worry about global warming?

NASA (National Aeronautics Space Administration) and NOAA (National Oceanic and Atmospheric Administration) agree that climate change is happening and humans are contributing to it. Many people agree in the United States of America and abroad. MAny believe it is because of greenhouse gases from humans. Scientists are trying to answer some very important questions such as how quickly will the world warm, and what consequences will that have on certain parts of the world. The global temperature average has risen by 1.4 degrees Fahrenheit over the last 100 years. NOAA said that the decade between 2000-2010 was the warmest decade on record. 2005 was the warmest year on record. There have been more intense rainfall and severe heat waves. Sea levels are rising. The Earth does go through warming and cooling because of factors such as sun and volcanic activity. The warming and cooling is partly natural and partly because of humans. The sun's energy has fluctuated but is small in comparison compared to human's effect. The warming is consistent with what happens with heat trapping carbon dioxide. Carbon dioxide can lead to climate changes that can hurt plants, animals, and people. For every 2 degrees Fahrenheit raise 5-15% reductions in crops. 3-10% increase in rain which would create flooding. 5-10% increase in stream flow. 200-400% increase in wildfires in the western United States. Scientists predict that the temperature will rise 2-12 degrees Fahrenheit by 2100. It is not too late too fix climate change!

This website is very interesting. It shows a map and when you click on a region it explains in detail how the climate change in that region has changed.

This is about the climate change that has happened in the USA I the pasted years. This is a government website and it is amazing.

I thnk this website is really good because of the regional map. When you click on an area it shows you how much global warming has really affected it in the past years. If enough peopl in the world look at it ( randomly ), it could help us cut back on harmful products.

This song is about the earth, and the way it's affecting us. He says "we can hardly breathe" which is a reference to the pollution and bad air that's in the atmosphere which trap the heat from the sun in. He is saying that humans are neglecting to consider the future!

This is a really useful website about future climate change and what is expected to happen with global warming up until the year 2099. It has a bunch of helpful diagrams and written information as well.

Climate change will have many affects of our world climate in the future. Rain pattern are expected to change drastically and that means that Colorado could have lots of rain and places like Maine would have arid climates. The Earths average temperature will rise, which isn't something new but this means that oceans will rise so much that they will flood islands and kost likeley the keys. Along with the increased sea level the Earth will get a higher pH in the oceans. Many areas that have used their climate to grow crops or do certain activities will face an impending change. Crops will die in places that turn cold. Melted snow runoff in the himilayas might flood village's. All of these changes depend upon the amount of greenhouse gases are admitted into the atmosphere. Natural features may play a role to. Say, a volcano eruption, could possibly speed up the process in said area of eruption. Overall many factors play into the climate change of the world and in the future bad consequences might come of the greenhouse gases that are going into the atmosphere. Reviewed by Tucker Hamilton

This site relates geology and climate change, and how climate change is shown within geological records. It also has a part on the greenhouse effect and other changes in the atmosphere.

Evidence for climate change is preserved in a many of earths of geological settings, including water and lake sediments and particles, ice sheets from ice ages and modern times, and fossil tree rings because thicker rings mean more water that years. Rock also provides intricate and detailed information about the climate. If a certain rock like limestone is found where it is a dessert than that means that there was once an ocean there which would effect the climate. There is geological evidence that when more co2 is released into the atmosphere it tends to make the earth heat and with that water levels rise. This is evident through the said process of rock types that was described. Co2 that is absorbed into tree rings also offers evidence of this. Overall, geology offers many different scientific clues about how to tell the climate of ancient times an places. Geology can be helpful to climatologists who want to compare data and prove their point of view.

This had good information but very little, it told how extrusive rocks are formed.

Great information but it is a little short.

Igneous volcanic rock and it forms when lava from inside the earth flows out

NASA analysis on the rocks

This is an interesting website. It's kind of weird that they named the rock. Why would they do that?

What mars rover is this from

An unconformity is when there is a missing layer in the rocks

Its a good site that goes through a lot of different rock layers.

The oldest rocks in Colorado are 1.7-1.8 billion years old.

This has good information about the tectonic plates, but it is very long. I also like it when I can see the part of the world the commentator is talking about. 1/2 of the time this part is on the other side of the world than the techtonic plate that is moving around.

It is really interesting how the tectonics plates are moving constantly and it clearly describes the Pangea thory

theory

This is a really informative website about stromatolites. I learned a lot about stromatolites in this article.

Stromatolites are the oldest form of life and are composed of many different types of bacteria hardened together. This website was pretty accurate and related to the Lykins era in Denver history.

I really did not know that 96% of marine life died. Also 70% of terrestrial vertebrate species were extinct.
