Answer:
The rock is denser than the water
Step-by-step explanation:
A rock is made up of many pieces of metals, such as granite, which have a higher gram per cubic centimeter than water does. The average rock has a density of 2.6 grams per cubic centimeter while water has a density of 1.0 grams per cubic centimeter, which means it weighs more per cubic centimeter, and causes it to sink.
