heated up‚ this orbiting matter accumulated and unavoidable mass of larger bodies collide to successively create protoplanets with its own gravitational pull. During this period‚ Earth was nothing but molten rock from the collision with other bodies and volcanoes‚ temperature reaching over 2‚000 fahrenheit. Not only that‚ but Earth then‚ would’ve been toxic to humans and modern life because of the lack of oxygen. Only carbon dioxide and nitrogen were presented and some water vapor. One massive planetary

Earth is changing Introduction We often think of the Earth as a stable and safe place to live. The landscape we see seems timeless and impossible to influence. At the same time‚ we know there are a lot of forces that affect our planet and change it. Some changes are quick‚ such as when earthquakes and volcanic eruptions break the ground or covering it with lava. Other changes may take millions of years‚ such as wind or the abrasive forces of water. The hunt for food‚ searching for land to cultivate

Life on this planet Earth is the product of a delicate balancing act provided by nature. Mankind’s very existence is totally dependent on this fragile ecosystem’s ability to maintain itself. A valuable player in the balance of the environment‚ the ozone layer‚ is facing a very serious threat by man. Chloroflourocarbons (CFCs)‚ are chemical agents commonly found in refrigerants‚ aerosol sprays‚ and in the manufacturing of Styrofoam and industrial solvents. With the rate of more than a half-million
