Is there also a relationship between the plate boundaries of Earth and volcanoes? Yes there is. Were some volcanoes are on the map there are some earthquakes too. For example there are earthquakes and volcanoes all along the west coast on the whole North American continent.

Plate Tectonics

The breakup of Pangea was 225 million years ago. The continental breakup that almost happened in Michigan occurred 1.1 billion years ago. The kind of rock that now fills the Keweenawan Rift is basalt. This happened during the Early Carboniferous period, 356 million years ago, Michigan was on the Equator at the time. The Mediterranean Mountains will be north of Africa in the future world. They say in 250 million years North America will be joined with South America and Africa.

Earthquakes

How many earthquakes have happened today?
Febuary 03, 2010- 10 Earthquakes
Most recent earthquake: California, Febuary 1st
Most earthquakes seem to happen in: California
Most earthquakes happen in South America around the Western coast.
As you go from west to east in South America the depths get deeper.

clouds.

Mammatus clouds are very harmless.

Lenticular clouds they are seen by mountains or hills.

Roll clouds caused by thunderstorms.

Noctilucent clouds form by sunsets.

White Christmas!

Thundersnow
^
Thundersnow is a thunderstorm than has snow reaching the surface instead of rain. Usually thunder and lightening are more commonly observed with warm season thunderstorms.


Rime snow
^
Rime snow is usually firm and crunchy. Rime snows forms on the top of other snow in very extreme weather.

Watermelon snow
^ Watermelon snow is usually pink in color and on the top of mountains in California or Nevada.

Firn snow
^ Firn snow is snow that has been left over from past seasons and has been crystalized.

UNFCC

The United Nations Framework on Climate Change Confrence or COP 15's goal for this week is to was to establish a global climate agreement for the period 2012 when the first commitment period under the Kyoto Protocol expires. It's different because it is linked to the UNFCC. The feature of the Kyoto Protocol is that it sets targets for 37 industrialial countries and the European areas for reducing greenhouse gas emissions.

3 way we can prevent climate change:
- reduce your carbon footprint.
- we can be smarter about choosing our seafood.

- we can change light bulbs!

I can use energy saving lightbulbs in my home so it saves money and helps the climate!

Nothing really tells us what did kill the dinosaurs , It remains a mystery. There are many theorys that might have caused the dinosaurs extinction. An asteroid could crash into the lithosphere which is the earths crust. It can cause earth quakes and volcanic eruptions. It can even effect the hydrosphere which is the solid, lliquid, and gaseuous forms of water on earth. It could cause floods and drought which means the dinosaurs either drown or can't get any water. This is a big one. If an asteroid came down and hit the earth it can easly affect the biosphere. All plant and animal life is in the biosphere. If an asteroid hits any of that it can cause food shortages and even forest fires. Pretty soon there will be no food or shelter for the dinosaurs to eat or live in and there comes along extinction. The asteroid can affect the earths atmosphere too. From all the dust and debree coming off the asteroid, it can make the air polluted and hard to breathe. Some dinosaurs could stop breathing and die. It could even be hard to see too! The spheres that could have been involved are the:
-Lithosphere
-Biosphere
-Hydrosphere
-Atmosphere
There is another theory of the dinosaurs becoming extinct. A volcano could have erupted causing fires, drought, and even kill some of the dinosaurs. There many more examples of what could of happened.
