Always in you, Sometimes on you;

If I surround you, I can kill you.

What am I?

A person was found dead on a big green land with no trees or buildings around. When the police arrived, they found a piece of rock lying next to him and the man was wearing clothes comprising of red, blue and yellow colours.

Can you tell who the person is and what was the cause of death?

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?

I know a nine-letter word having only one vowel.
Do you ?

If you say my name, I will no longer exist. What am I?

A wooden log balances equally on the scales when weighed with three-quarters of a pound and three-quarters of a wooden log.

Can you calculate the weight of the entire wooden log?

It comprises roots which nobody sees,
Much taller than those trees,
Up and up it goes,
Still it never grows?

What breaks yet never falls, and what falls yet never breaks?

If six children and two dogs were under an umbrella, how come none of them got wet?

I live in a bowl. I can swim. I have a tail. I also have fins and big eyes. What am I?
