The first part is simple, you need three things for a fire:
Heat
fuel
Oxygen
You get liquid oxygen that is mixed in with the just fuel before it ignites.

Why are rockets used to get to the moon?
There is no atmosphere or oxygen in space, therefore rockets provide thrust by burning fuel with oxygen on board, or an solid that produces oxygen as needed.
Where do some rockets get their oxygen from?
Liquid fueled rockets get it from liquid oxygen, and solid fueled rockets get it from and oxidized metal.
Why do rockets need to carry a supply of oxygen?
Rockets need to carry a steady supply of oxygen so that the fire that takes them off of the ground can burn. You must remember that to have fire you must have oxygen.
Why are some rockets fueled by liquid hydrogen and liquid oxygen?
unlike solid fuel, liquid fueled rockets are capable of being throttled, shut down, and restarted.
Why are smaller rockets needed on the moon?
the moon is small and we don't need much space

What is the use of oxygen in the rockets?
It is used as oxidant in the rockets.
Why do rockets engines in space have to carry their own oxygen?
Fire needs oxygen in order to burn, and there is no oxygen in space, so rockets must take oxygen with them.
How do rockets get oxygen?
an elephant
What propells bottle rockets?
The force of energy and oxygen propells bottle rockets.
Why in rockets using oxygen?
because in outer space there is no oxygen
What is the difference between water rockets and modern rockets?
Water rockets use water and air modern rockets use thrust and oxygen.
What do rockets use?
Hydrogen and oxygen as fuel
Why do rockets need to carry a supply of oxygen?
Rockets need to carry a steady supply of oxygen so that the fire that takes them off of the ground can burn. You must remember that to have fire you must have oxygen.
Where do fireworks and space rockets get their oxygen from?
They take it with them in some form or another. Fireworks use oxidizing salts such as various nitrates and chlorates. Solid fuel rockets generally use ammonium perchlorate as an oxidizer while liquid fuel rockets carry liquid oxygen.
How can you use oxygen in rockets?
Liquid oxygen and liquid hydrogen are used as rocket fuel, oxygen gas is used by the astronauts to breath.
