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:

radiative zone

explanation    

radiative zone is the layer of the sun which energy is transferred away from the core by radiation. although, the core is the only part of the sun that produces an appreciable amount of heat through fusion. in fact, 99% of the energy produced by the sun takes place within 24% of the sun's radius.
