using, producing or resulting from nuclear energy

the mass of salt water that covers most of the earth’s surface

a large round object in space that moves around a star (such as the sun) and receives light from it

a raised line of water that moves across the surface of the sea, ocean, etc.

a chemical, usually a liquid, that contains hydrogen and has a pH of less than seven. The hydrogen can be replaced by a metal to form a salt. Acids usually have a bitter sharp taste and can often burn holes in or damage things they touch.

that cannot catch or be affected by a particular disease or illness

a device that gives out light in which all the waves oscillate (= change direction and strength) together, typically producing a powerful beam of light that can be used for cutting metal, in medical operations, etc.

a chemical element. Oxygen is a gas that is present in air and water and is necessary for people, animals and plants to live.

a substance, found within all living things, that forms the structure of muscles, organs, etc. There are many different proteins and they are an essential part of what humans and animals eat to help them grow and stay healthy.

powerful and very dangerous rays that are sent out from radioactive substances
