Journal Entry 3 – Colliding Plates
Overall the practical went pretty great and went reasonably fast and easy to understand. It was simple to get the idea about tectonic plates and a practical look at what it should be like underground. Overall our group finished the practical very easily and had no problems at all completing it. We also ended up learning about Tectonic Plates and just a practical look at what their reaction with another plate is.
Questions
- Compare the above tests with plate tectonics.
This practical teaches us of a practical representation of what occurs when two tectonic plates collide.
- The Stack of Paper had obvious layers. Assess whether rock has layers, and if so explain why.
Yes rocks do have layers. This is mainly due to sedimentary rocks which are basically when sediments form on a rock. This over time does create layers and also can explain how old a rock is. This is dependant on the amount of layers of sediments that the rock contains.
- State which tests simulated the following collisions.
a) A continental plate with another continental plate – Test 1
b) An Oceanic Plate with another Oceanic Plate – Test 3
c) An Oceanic Plate with a Continental Plate – Test 2
- Identify a place on earth where each of these collision types occurs.
A Place on the earth where these sort of incidents would occur is somewhere like Hawaii which is prone to volcanoes etc. There is only a need for tectonic plates colliding (continental or oceanic) to make any of the tests which we performed be real.
