When dry sand and water are both exposed to equal amounts of light, you will find that water is cooler than sand.
This is because the amount of heat needed to heat the water is less than that needed to heat sand, thus, sand heats faster.
Answer: See explanation.
Explanation:
Because Astronomers have well-tested theoretical models that explain how a star evolves over the course of its life as well as well-tested theoretical models that explain how a star evolves over the course of its life.
