Just tectonic!

What evidence is there that the plates have moved?
"What evidence is there that the plates have moved?" asks Dusti. Well, Dusti, there is a lot of evidence to show, because when the plates collide, pull apart or grind past each other they make things such as volcanoes, mountain ranges, and deep ocean trenches. The plates meet at plate boundaries. There are three kinds of plate boundaries: Divergent boundaries, Transform boundaries, and convergent boundaries.
Don't get down about erosion!
Erosion the process of eroding or being eroded by wind, water, or other natural agents. ((Definition from Wikipedia.)) The 3 main types of erosion are wind, water and ice. The most changing of these 3 is water. The weakest is wind, and in the middle is ice.
Volcanoes
Volcanoes are a force not to be messed with. With poison gasses, chocking ash and burning lava, these death traps are a mighty impressive force. On the other hand, these mighty volcanoes have helped change the surface of the earth. A great example of the good side of these beasts is Hawaii. Gentle lava flows cool to make the island bigger and bigger.
Earthquakes
You feel a shaking in the ground and a giant rumbling noise. The ground splits up and a tall building comes crashing down! You are in a earthquake, a dangerous force that can change the Earth's surface.
Meteorites.
Streaking through the sky, a rock from space is coming at you with extreme speed. What is it? It's a Meteorite. These can fall from space and make huge craters. A good example of craters from meteorites is the moon!
Fossils
The law of Superposition
The law of superposition is about rocks and the layers of rocks. The deeper we dig, the older the rock is. The top layer is the youngest.
How can fossils tell us about the history of the earth?
Well, we can study the fossils to find out how they died, what their skeletal structure looks like, what they ate, and what the time period they came from was like.
Are all fossils the same?
No! There are many different types of fossils. There are
- mold fossils
- cast fossils
- trace fossils
- true form fossils
They are all made differently and will never be the same
Igneous rocks
This rock is formed by the rapid cooling of lava, or magma. It cools so fast that crystals don't form!
Metamorphic rocks
Metamorphic rocks are formed by heat AND pressure.
Sedimentary rocks
Sedimentary rocks are formed by pressure. Many layers are seen with Sedimentary rocks
The rock cycle
The rock cycle starts at sediment rock from sediment. When rivers carry down sediment it weighs down into layers. Then, when it gets really hot but not hot enough to melt the rock all the way.When it does get hot enough the rock melts and turns into igenous rocks
How minerals are formed and how we identify minerals.
A mineral can form when magma or lava hardens, or when a solution evaporates. We can identify minerals by their lust, hardness, color, and shape.
All about me
Hi, I'm Grey and I'm the one who made this flyer. I like anime like AoT and hetalia.
This project.
I didn't really like it because it was kinda hard and... i totaly forgot everything so i had to reread the whole chapter. :D But it was fun!
