Earth is the fourth planet in the solar system and only incidentally the only heavenly body known to host and support life. Only a fraction of the Earth’s surface (about 2.5%) is covered with land, consisting mainly of islands and continental shelves. About 66% of Earth is covered with oceans, and about the same percentage (66%) is covered with atmosphere. The remaining portion of the planet is made up of watery oceans, lakes, ice caps, etc. The Earth obtains sufficient heat from its orbit to be very cold, and an extremely dense planet, which is very rare, if not unique, in the solar system.


The center of the earth is at a north-solar point, where the planet’s equator passes through the plane of the earth’s orbit. The earth’s axis of rotation is tilted such that the mean inner pressure of the earth is near the Equator – thus defining the latitude of the location of the planet. The earth spun off from a relatively recently forming super cloud (an Orogen cloud) at the center of the Orogen Cloud and is now spinning off into its own orbit, which is spiraling around the sun. Because the planet spun off from a cloud of relatively cool gas, the earth is very hot, and the atmosphere is very light (just slightly lighter than the earth’s average temperature).

The earth revolves around the sun, which moves across the nasa plane at speeds comparable to the earth’s own rotation. Because the earth spins very fast, there are some areas on the earth system that are very dry and others that are very wet. The difference in areas of different continents can mean different climates. Some areas are quite warm, but cold (tropical), while others are extremely arid and warm (desert). It is estimated that the earth system contains about two hundred and fifty billion trees. That adds up to about two percent of the earth’s mass.

The solar system is extremely fluid as well, but because the inner core of the planet is so hot, there is very little that the average person can see. The outer layers of the solar system are so dense that they do not allow gases and water vapors to escape, and therefore they have no effect on the climate of the planet earth. About 95% of the surface area of the earth is covered by oceans, and there is another ocean in the “galaxy” beyond the earth’s atmosphere, called the Oceans. The remaining portion of the solar system consists of rocky Outer Space and an extremely thin atmosphere.

The Oceans contain oceans that are relatively deep and therefore have low temperatures – they are also very hot. Because of the lack of atmosphere, there are oceans of ice, and there are clouds of gas. The amount of heat in the atmosphere depends upon the difference in pressure between clouds and the earth, and it varies greatly from place to place within the solar system. The colder the pressure, the hotter it is, and so on.

We live on a very blue planet, called Earth. If you measured the temperature of the earth, you would find that it is about minus 300 degrees Fahrenheit. The oceans are about a billion gallons deep, and they contain more than two hundred and fifty different types of oxygen. There are two oceans – one near the equator and one near the moon. If you took all of the oceans and placed them into the exact center of the earth, it would create a sphere of water about ten times the diameter of the earth.
