Earth is the outermost planet in the solar system and only the only stellar object known to harbor living organisms. Over 29.2% of Earth is made of land, consisting mainly of islands and continents. Over half of the Earth is covered with water, which acts as a protective layer and prevents temperatures from rising too high or cooling too low. The remaining portion of the planet is covered by atmosphere, making Earth a cool and very warm planet in many ways.
When people began to explore the world, they noticed that it wasn’t really very easy to get around without an air-conditioner or some form of heating device. It also became apparent that people were way out of touch with the Earth. In 1855, Sir Edwin Landseer described the poles of the earth as ‘frozen rocks.’ It was further discovered that the poles were actually moving, which greatly disappointed geologists. In the decades since, more theories have been put forth as to why the earth is so important to us today. Many scientists believe that the earth is essentially a living planet, where different types of life can exist, including microbial life, animal and insect life, and even alien life forms.
Because it is extremely hot, Earth was able to accumulate solar radiation and heat long before NASA and other space agencies came along. It took millions of years for radioshape models to be created and analyzed using technology that is similar to what we use today on earth. One of the greatest theories on why the earth is so special is due to how it holds a nearly endless supply of energy. Every minute, every second, and every fraction of a second, the earth sends out waves of energy which are picked up by its orbit around the sun. These waves, unlike the radiation received by our planet, are completely beyond our comprehension.
Astronomy is one branch of science that has been directly impacted by the study of earth. When the first space ships were launched into space, they studied the effects that the earth had on its own orbit around the sun. Over time, they found that the earth is extremely elliptical, with its poles never far from the sun, and its equator always near. The day/night seasons on earth affect the amount of radiation our planet receives. For example, when the days are cloudy and cold, the earth receives less radiation, while when it is sunny and warm, the earth’s radiation increases dramatically. Studying the earth’s wobble, or tilt, we can better understand space weather, or space weather patterns, and how these could affect our space travels.
Another big reason why studying earth is important is because of the way our solar system works. Like all other outer space objects, it was created in theact of formation, millions of years ago. During the times when our solar system was young, very little material was produced on the order of 100 Myr. This small amount of material is what formed the earth, including its atmosphere, the moon and planets. By studying the properties of the earth, we gain a better understanding of how these bodies were made, and why they are here today.
So, if you’re looking to go out and study earth, there are plenty of options for you to choose from. You can spend money to go on an earth study abroad program, which sends you to a university or other such place where you can study for a semester. You can also go on a balloon ride to the inner space, or even take a trip to the moon. These are great ways to learn more about earth, and get a better idea about our space program, and how we’re using our outer space possessions to benefit mankind on earth.
