As temperature changes, rocks expand and contract. The rocks eventually break into
smaller pieces. Which process accounts for
this expansion and contraction of rocks?

Thermal heating and cooling

Explanation:

This process described results from thermal heating and cooling as a mechanism of mechanical weathering of rock bodies.

explanation:

crosscutting concepts have application across all domains of science. as such, they are a way of linking the different domains of science. they include patterns; cause and effect; scale, proportion, and quantity; systems and system models; energy and matter; structure and function; and stability and change.
