environment plays an important role in the healthy living of human beings. it matters because it is the only home that humans have ,and it provides air, food and other needs. Humanity's entire life support system depends on the well -being of all the environment factors.

It has a solid and active surface with mountains, valleys, canyons, plains and so much more. Earth is special because it is an ocean planet. Water covers 70 percent of Earth's surface. Earth's atmosphere is made mostly of nitrogen and has plenty of oxygen for us to breathe.

Other than maybe Europa, Earth is the only planet that currently has liquid water (planets like Mars used to have water). Also, Earth has a substantial amount of oxygen that allows it to support life, and it has the perfect amount for fires to burn.

The four inner planets, or terrestrial planets, have solid, rocky surfaces. Earth, the third planet from the Sun, is the only planet with large amounts of liquid water, and the only planet known to support life. Earth has a large round moon. Mercury is the smallest planet and is the closest to the Sun.

It is useful to categorize the requirements for life on Earth as four items: energy, carbon, liquid water, and various other elements. These are listed in Table 1 along with the occurrence of these factors in the Solar System (2).

The scale ranges from -81 degrees C (-114 F) in black/blue to 47 C (116 F) in red. Earth is the only planet we know of that can support life. The planet is not too close or too far away from the sun. It lies in a "Goldilocks zone" that is just right — not too hot, not too cold.

Earth is one special planet. It has liquid water, plate tectonics, and an atmosphere that shelters it from the worst of the sun's rays. But many scientists agree our planet's most special feature might just be us.

A special planet: the habitable Earth What makes the Earth habitable? It is the right distance from the Sun, it is protected from harmful solar radiation by its magnetic field, it is kept warm by an insulating atmosphere, and it has the right chemical ingredients for life, including water and carbon.
