Question

What major factors have enabled life to evolve and survive on the Earth?

Answer 1

All the factors necessary for sustaining life-forms are present only on Earth. It has an atmosphere containing gases like oxygen and carbon dioxide, which are necessary for life. It also has abundant water, which is extremely essential for sustaining life-forms. The adequate distance of the Earth from the Sun and the suitable atmosphere around it maintain the right temperature for living organisms to survive on the Earth. It also has a ozone layer in its atmosphere to stop the harmful ultraviolet rays of the Sun from reaching the Earth's surface.
