Which may result from an increase in friction? check all that apply. increased traction increased speed decreased speed generated heat reduced wear and tear

The answer would be A,C, and D. Think about it friction is when two things rub together while those are rubbing together they can decrease the speed of an object trying to move across the surface, while doing so it can also produce heat (like rubbing your hands together for example) its simple!!! Hope this helped

The zone your looking for is the intertidal zone.
