hello
Diversity refers to how many different species are in an area or belong to a given group of organisms.

Scientific evidence suggests that life began on Earth approximately 3.5 billion years ago. The Earth formed 4.5 billion Years ago. The Earth was a dead planet for about 1 billion years. Some evidence would suggest that the first forms of life began more like 3.8 billion years ago, in which case the Earth was dead only 700 million years. The study of the processes which resulted in the beginning of life is called Abiogenesis. If it worked the same on other planets on other Sun in other galaxies, life may have begin 10 billion years ago in other galaxies. See related links. Note also that there are dozens of explanations for the beginning on life on Earth, including many based on religion.
First of all u must know dat carbon forms bonds with many elements.So carbon is stored in the forms of gases like CO2 & CO etc in atmosphere.In living beings,the entire body is made up nearly of carbon & trees also store them.In case of your body,one example is the fat. Science life on earth is based on chemical reactions of Carbon compounds,generally with hydrogen, earth is said to have Hydrocarbon form of life.
Yes. Planet earth has many forms of life. However apart from on Earth there is no other life that we know of.
Yes, Earth has many different kinds/ forms of weather like raining, snowing, sunny, etc., etc.
Actually, it is the many species of insects that outnumber the animals.
There is almost certainly life out there in outer space. It could come in many forms, from protozoa, to intelligent life forms, to life forms unlike any that are found on Earth. There could be basic life forms on Mars, the satellites Titan or Europa. It is more than likely the nearest life forms on another place in the universe is countless light years from Earth, and there is an excellent chance, we will never know about these other life forms because they are too far away for us to reach travelling at far less than the speed of light.
Life "as we know it" is a term which covers the many and varied forms which life on earth takes, from intelligent animals down to single-celled amoebas.
hello
It comes in many different forms and is very stable(does not decay quickly)
The Earth is 4.5 billion years old. Life has been around for 3.5 billion years. Complex life forms originated about 500 million years ago. There is no telling if/when life will cease to exist on Earth or if/when it will be destroyed in space.
A place in which there are many different life forms,cultures, religions, races and home to many eratic seahorses.
significant changes occur in the ecosystem
Currently there are no known alien life forms. If alien life exists it probably comes in many varieties. However, if life on Earth is any indicator, it is unlikely that aliens would have multiple heads. In all animals on Earth, multiple heads only occur with birth defects.
EARTH,PHYSICAL, AND LIFE SCIENCE ARE THE DIFFERENT STUDIES OF SCIENCE
