You can do this in your car and it is a lot of fun. It leaves marks on the pavement and some people get annoyed with the sound! You can feel this at work and it is not so fun. It leaves mental marks and can be related to depression.

I offer heat and endless sand, or slip away from a post or stand. I’m harsh in land or swift in choice, one word that carries either voice.

I am everywhere except for where things are. The more of me you have, the less things you have. I surround the Earth yet I take up no room. What am I?

What is full of holes but still holds water?

I'm round in the beginning, high in the middle and round at the end
