which term describes weathering?\nbreaks down rock\ncauses heating and cooling\nmakes pebbles and rocks…

Brief Explanations:

Weathering is the process by which rocks are broken down into smaller pieces through physical, chemical, or biological means. Heating - cooling can be a part of physical weathering, but the main result of weathering is the breakdown of rock. Transporting fragments is erosion, and making pebbles and rocks larger is not related to weathering.

Answer:

breaks down rock
