Science project I need help on?

Question

Help i am doing a project for these questions and can't find them online or on my texts books.

1. Tectonic plates are either oceanic crust or continental crust and when plates collide there are three possible collision scenarios. What are they?

2. What do you find that is similar between the location of volcanoes and the location of earthquakes?

Answer 1

Answer to Question 1:

Three possible scenarios... Visualize two slabs of rubber moving toward one another like big mattresses off of peoples' beds. At the meeting point the slab on the left (for example) can go down under the slab on the right (1), go up over the slab on the right (2), or the two of the slabs can collide and go straight up in the air making a big ridge or string of mountains (3).

Answer to Question 2:

Volcanos always seem to lie along the path of the cracks in the Earth's crust where this shifting and colliding seem to occur. A good example is that string of islands of the Aleutians (spelling?) just north and west of Alaska. The Earth's crust is shifting there and many islands that have been created by volcanic activity.

Answer 2

1
i plates can slide,grind past each other along transform faults.

ii one may ride over the other forming either a subduction zone (if one plate moves underneath the other) or a continental collision

this can be ;
oceanic/oceanic,
oceanic/continental,
continental/continental,

....third one ... two plates can slide apart from each other
(but thats not a collision.

2. near to fault lines
