Plate Tectonics
Caleb K.
What evidence is there that plates have moved?
This is the evidence that plates move. One, earthquakes. Plates are the big pieces of land that move. The type of movements are compression, tension, shearing. The different type of boundaries are divergent, transform, convergent.
Earthquake
Earthquakes knock buildings down and create tsunami's. They also create holes into the ground that can make the plates move.
Volcanoes
They help the soil. They also create a whole bunch of ash which kills people if it touches them. It takes away trees and many houses.
Tsunami
Tsunami's knock down anything in the way. They cause a lot of flooding. They also knock down houses and kill people. It changes the entire environment.
What is erosion.
Erosion
Erosion is the breaking down of rock. Which is broken down by ice, water, and wind. The three main types of erosion is ice, wind, and water. Water creates the largest change in earths surface. Wind creates the littlest change in earths surface.
Law of superposition
Law of Superposition is when the rocks deposit the youngest goes to the top.
They tell a lot
They tell us a lot because it shows us the different animals that are now extinct. It also shows how big they were and shows how we have changed
No
Fossils are usually never the same. They are all different usually.
rocks and minerals
Rock cycle
The metamorphic rock goes to magma, then that cools down and turns into an igneous rock. Then the igneous rock turns into sediment, which creates sedimentary rock. Also metamorphic rock also can turn into sedimentary. Igneous also turns into magma.
minerals
Minerals form by a natural occurring, inorganic solid that has a crystal structure and a definition chemical composition. Each mineral has characteristics properties that help to identify it.
What i liked
I liked looking up the different rocks and minerals. Also the games we played.
