plate tectonics

  

                                        plate tectonics theory

The plate tectonics are the movement of the crust on the land from 2000 million years until what we get today.

In the past, 220 millions years ago all lands was together and that's called Pangaea. This catastrophic extinction and continental rearrangement opened The way for the rise of the dinosaurs and mammals. After that time the continental start separating, it's broke slowly a parts this called theory of continental, in 1912 Alfred Wgnere thought of it, and the Evidence is Puzzle, fossils, Rock, Mountains because it fit together.

What causes the earthquake is movement of the fault, which has three types such as normal fault the rock move down, reverse fault the rock move up, and strike –slip fault the rock both slide of the side to side, when the earthquake start from focus and epicenter is begin to seismic waves, then seismograph is to measure the p- wave, S-wave- and L-wave.

Also there is convergent boundary which it create volcano, Subduction zone when the oceanic plate going the less densit goes underneath more densit, so when the heat force the plate to move under the ground 

The plate tectonics is the movement of the lands, and it mad of continental drift which is all the land was together then it separate slowly into a parts, and effect that happen when the earth is moving it happen an earthquake, and also the convergent boundary create a volcano.

Reflection

1-    The most that I enjoy about this project is making music because it was fun and how we try to make a song for a topic.

2-    The most challenging was to make a video with recording my voice and to put a music and background.

3-    I learn what was the earth look like before and what is the causes and the effects of the earth.

4-    If I fix my video in the I photo and if I record my voice it will be more better.

5-    If I could change the project I will not change anything but I will work more harder to make my project even more better .
