The Dynamic Earth

This week we studied The Dynamic Earth. We visited a few websites and the best one that we found was-
http://www.mnh.si.edu/earth/main_frames.html This website tells all about Plate Tectonics, Gems and Minerals and Rocks and Mining. I choose to study Plate Tectonics and Volcano's and Rocks and Mining. In the Plate Tectonics section I studied The Inner Earth and The Unreachable Frontier. In the rocks and Mining section I choose to study Rocks Tell Stories and Water Recycles Rocks. Down below I will show you what I learned.
Plate Tectonics and Volcanoes

The Inner Earth-

• the inner earth is layered
• beneath the surface is a rocky and cold mantle and core
• the inner earth is very very hot
• the earths core is hotter then the surface of the sun
• the inner earth flows
• in the mantle the flowing rocks help the tectonic plates move them
• during Earth’s first 100 million years large particles in the Solar System collided and stuck together making tremendous heat.
•  dense molten iron sank and created the core

Rocks and Minerals

• lighter silicate liquid rose and cooled forming the mantle
• later the melting of the mantle produced the crust a process that continues todayThe Unreachable Frontier
• more than 99 percent of the distance to Earths center still leys beneath the drill bit
• the inner earth is very hot so tahts why we cant reach it
• scientists gather information from meteorites, rocks, diamonds and earthquake waves
• scientists can learn about the inner Earth from special rocks called peridotites
• sulfur, alimumum, calcium, magnesium, sislicon, oxygen and iron are the main 7 elements taht amke up the earth
• the magmas that erupt at earths surface come from partial melting of peritonitis

Rocks Tell Stories

• rocks are solid natural aggregates of minerals
• in each rock they tell a different story
•  within earth water plays a critical role in transforming and melting rocks
• water is hidden in tiny pores between mineral grains in a rock of course
• every rock isn a piece of earths history
• rocks are clues taht help us predict about the nature and timing of the events that formed them

Water Recycles Rocks

• water creates shapes and destroys rocks as it travels among land, sea, and air
• the mississippi river spills into the Gulf of Mexico and transforming loads of sediment
• the ocean water evaporates into the atmosphere

That is all that I learned from this website. It helps a lot and it contains many more interesting facts about the inner earth, minerals, caves and so on. This website answered so many of my questions but while it answered my old questions, new ones popped into my head while responding and writing and reading all the information. Some of my questions are- why is earth layerd? Why is the Inner Earth hotter then the suns surface?  Why are rocks pieces of history and other things like the deserts arent?  There is so many that my head is full of huge ? ? ?  that can be answered only by reading! So visit the website and get some Awesome Knowledge!!!!! I hope that you enjoy the website just like I did!!!!!
