If I remove one from eleven it becomes Ten and if I remove one from nine also becomes Ten. How?

My first is in chocolate but not in ham. My second is in cake and also in jam. My third at tea time is easily found. Altogether, this is a friend who is often around. What is it?

I can sizzle like bacon,
I am made with an egg,
I have plenty of backbone, but lack a good leg,
I peel layers like onions, but still remain whole,
I can be long, like a flagpole, yet fit in a hole.

If eleven plus two equals one, what does nine plus five equal?

There are five vowels (a, e, i, o, u) in the English language.

I look flat, but I am deep. Hidden realms I shelter. Lives I take, but the food I offer. At times I am beautiful. I can be calm, angry, and turbulent. I have no heart but offer pleasure as well as death. No man can own me, yet I encompass what all men must have. What am I?

Lifeless eyes on my smiling face and watch your child's sleeping place. In their dreams they hold me tight. What am I?

What has one letter and starts with an E?

My thunder comes before the lightning; my lightning comes before clouds; my rain dries all the land it touches. What am I?
