Tectonics Lesson 5: Conservative Plate Boundaries

Question 1

What happens at a conservative plate boudnary?

Answer 1

2 plates slide past one another resulting in a major break in the crust between them as they move.

Question 2

What is the break in the crust known as?

Answer 2

Fault but on a large scale this is a transform fault

Question 3

What is the movement of a plate to the left known as?

Answer 3

Sinistral

Question 4

What is movement of a plate to the right known as?

Answer 4

Dextral

Question 5

How are the two plates different from each other?

Answer 5

The plates travel of different speeds

Question 6

What are earthquakes like at conservative plate boundaries?

Answer 6

Shallow and powerful occurring from the frictional resistance. Shallow due to no Benioff zone forming

Question 7

Example of a conservative plate boundary

Answer 7

San Andreas Fault

Question 8

When was the last major earthquake at San Andreas?

Answer 8

1906 at an 8.3 magnitude

Question 9

Why will the next earthquake along the San Andreas be a large one?

Answer 9

Not been a major earthquake for a long time, so the pressure and friction has been building for a long time, and the fact that earthquakes along conservative boundaries are shallow, the big one will cause much damage and destruction
