Icebergs are large floating pieces of ice that have broken off from a snow formed glacier or ice shelf. They consist of freshwater rather than saltwater even though they are found in the ocean. For an iceberg to be classified as an iceberg it needs to have a height of greater than 16 feet (five meters) above sea level and the thickness must be 98-164 feet (30-50 meters). It also needs to cover an area of at least 5,382 square feet (500 square meters). Floating pieces of ice that are smaller than this are called bergy bits or growlers.
Clouds are a collection of tiny droplets of water and ice that have been evaporated from the surface of the earth. Clouds come in many different shapes and sizes and exist at different levels in the earth’s troposphere. There are three main types of cloud; they are stratus cloud, cirrus cloud and cumulus cloud. There are other scientific terms for specific clouds that are a combination of these names. Clouds appear darker when they are heavy with water or very dense. This is why you often see dark clouds before a storm.

They are simply called black hole because that’s what they look like in space.

A mutation is a permanent change in the DNA sequence of a gene. Genetic mutations are those that are passed on from a parent to a child and through families or are acquired during a person’s lifetime. If it is a hereditary mutation the damage to the cell in the parent is passed on through their DNA to their child. In some cases this causes illness and disease, in other cases it is not harmful at all. Acquired genetic mutation can be caused by a number of different factors such as radiations, sunlight, viruses, transposons and mutagenic chemicals.
