Questions from practical

1. Compare the above tests with plate tectonics
2. The stack of paper had obvious layers. Assess whether rock has layers, and if so explain why.
3. State which tests simulated the following collisions.

1. a continental plate with another continental plate
2. an oceanic plate with another oceanic plate
3. an oceanic plate with a continental plate

1. Identify a place on Earth where each of these collision types occurs.

1. In test 1 one plate tectonic will rise on top of the other. In test 2 one plate tectonic will subduct under the other plate. In test 3 one plate tectonic will rise on top of another plate staying still.
2. Yes, rocks do have layers because when they are formed they are made up of little layers which combine together and form a rock.
3. a. Part (A) relates to test 1 which shows to plates colliding with each other. (spreading zone)

b. Part (B) relates to test 2 which is one plate going under the other (Subduction zone)

c. Part (C) relates to test 3 because it is one plate going over the other plate (Collison zone)

       4. An example of Test 1 is when two continental plates collide and that is how the Himalayas were formed. An example of test 2 is when one oceanic plate hits another oceanic plate and that is the islands Japan, Indonesia, the Philippines, the Caribbean and the Aleutians. An example of test 3 is an oceanic plate hits a continental plate and that is the Andes Mountains.

In this practical in investigated three tests relating to colliding plates. The first test involved two continental plates colliding with each other. The second test involved an oceanic plate colliding with another oceanic plate. The third test involved a oceanic plate colliding with a continental plate.

From this practical i have learnt that for each test that was performed a different result was given for each one. I also learnt that volcanoes, Earthquakes, mountains and other natural disasters are formed by plates colliding with each other and going ontop of each other, under one another, and just colliding and going up.
