to make things cold and some food can get rotten if there stay outside

Things that walk or stay in the ground.

things stay where they are by no force acting on it

Things stay warm by preventing the thing it's keeping warm from losing heat. Some things that keep things warm are wool, tin foil, wood, glass, plastic, and rubber. Things that keep other things warm or cool are called insulators.

Living things don't normally stay the same as long as non living things do. Most living things will die before a mountain crumbles.
