I have four wheels but cannot drive, I hold your food but am not alive. You push my back to make me start, I travel lines but have no heart. You leave me when your shopping's done, I wait in rows for everyone.What am I?

I guard a secret stamped in wax, I dive where icy waters freeze. I keep the pressure from attacks, And fight for freedom on the seas. What am I?

I claim that I love to bring peace to the land, While gripping tight reins with an eager, fierce hand. I make veiled threats with a loud, blustering roar, Yet my footsteps lead straight to the threshold of war. What color am i?

Twist me in a bottle, Fear me in a storm, I'm the same, just bigger. What am I?

I can be a tasty breakfast treat, Or a trick you can pull on the street.
