All About Plate Tectonics
Text z Príbehu
- In an advanced society where humans have the highest of immunities and advancements even the past can awe about....
- Any questions regarding islands, class?
- Yeah, so how exactly are they formed?
- It all starts down at the bottom. In a divergent boundary, plates are pulled apart at a rift zone/ mid-ocean ridge by forces occurring in the mantle.
- As the plates pull apart, the mantle becomes depressurized and starts to melt. As a result, the melted mantle travels up through the rift zone to the surface, creating a volcano.
- Any other questions? If not, let us go to the next geological feature
- *Snap*
- In front of us, class, is the beautiful Himalayan Mountains of Asia. Isn't it beautiful?
- Woahhhhhhhhhh
- How did the Himalayan Mountains come to be?
- In my hand is a visual of a convergent boundary. Which is what the Himalayans is. In this case, two continental crusts will collide
- The upper portion of the continental crust is too buoyant to subduct into the mantle, while the lower part of the crust will subduct
- As the two plates collide, the part that is not subducted will be forced to get pushed upward, creating the mountain shape we all know and love
- Any further questions? If not, let us go to our last geological feature in San Andreas.
- *Snap*
- Can you guys sit down????
- *Snap*
- WERE WATCHING A MOVIE!!!
- Sorry class, wrong San Andreas
- Here we are at the lovely San Andreas Fault in the beautiful state of California
- So why exactly are we here?
- The reason I brought you guys here is because the San Andreas Fault is a real life example of a transform boundary.
- Plates are neither created or destroyed, but will cause earthquakes.
- In a transform boundary, two plates slide past one another, causing a fault between the two plates of the lithosphere.
- Okay class, it seems like were experiencing an earthquake. WE NEED TO LEAVE NOW!
- *Snap*
- *Rumble*
- *Rumble*
- *Rumble*
- WHATS GOING ON!!!!
- Luckily, they made it back to their classroom safely. Unfortunately, the state of California has been struck by an earthquake that hit a 7.0 on the Richter Scale, leaving the state in destructionThe End
