What force is present at a transform boundary

The correct answer is Shearing.

Explanation:

The transform boundary are those places where the plates move from one side to the other and are located at the bottom of the ocean, where faults can occur.

When these plates suffer an unbalanced voltage distribution across them, a rock failure is generated and this type of event is called Shearing.

An example of this formation is the San Andreas Fault.

Mostly, shearing can be divided into two types:

the answer would be the third option, "no, ariel should have added 9^2 and 12^2 and compared that to 15^2."

this is found through the pythagorean theorem, which is a^2 + b^2 = c^2.

this is the correct way of solving the problem:

9^2 + 12^2 = 15^2

81 + 144 = 225

225 = 225
