Earth from Space

How is Earth affected by what happens above it and below it? The Earth system is highly complex. To truly understand it we need more then just what our eyes have to offer, like the help of 120 satellites that are orbiting in the space every day. There are many satellites with many different purposes that help us narrow down many different factors that affect the Earth. As we go on we will see how earth, water and wind join together to perform cycles that keeps the Earth going. Earth as we know is constantly changing and through this essay I will go over some of the main factors that help us better understand what is going on around us. The Earth is always going in a constant cycle that consists of interactions between the sunlight, moisture, land and atmosphere.

The first main part of the process is what the sun does to the Earth. Its located 93 millions miles away from the earth but still has a massive role in helping all ecosystem on the Earth. The sunlight that hits the earth is actually a massive flow of energy that the earth receives from the sun. It helps warm the Earth, and also it’s force moves every organism on Earth. NASA’s latest satellite called “Polar-orbiting Suomi” helps us measure the impact of the sun’s rays on the Earth. It’s the size of a school bus and it orbits 500 miles into the sky while going around the Earth fourteen times a day. With the help of technological advanced sensors it reveals what the naked human eye was never able to see. The sunlight hit’s the sun at different points on the earth, which causes variation on how much heat, is absorbed by the Earth. The amount of heat at the Equator of the Earth would be much greater then at the poles. At the poles, there is less sunlight, which means it’s much colder there. But that’s not the only reason, since the ice at the poles reflects back the sunlight causing it to absorb very little. There is more heat at the equator because there is more sunlight directed towards it. Also, it absorbs more because there isn’t ice to reflect the sunlight back towards the sun. The fact that the equator receives so much heat can also affect what is going on around the world at the microscopic level. Lets talk about how the sunlight affects the sea and its temperatures. The heat from the sun causes the temperature to rise, which ultimately causes a gas called Water vapor. Water vapor can’t be measured without the Aqua satellite because it is even lighter then air. It’s the energy we don’t particularly see and its like molecules running from the ocean as they take the heat energy with them. It only needs to go towards space about half a mile as the air chills down and it condenses back into liquid. In the process it releases the sun’s energy and also the heat that it received causing what we know as Storms. The result of evaporation is visible by the naked eye; the heat is raised upwards about ten miles with the clouds. The earth rotation causes them to spin into a hurricane. The process of evaporation happens all around the world but the outcome is different at different places. The sun also affects plants on Land and Sea. It helps them photosynthesize and grow but ultimately it’s helping us obtain the oxygen we need to breathe. Its always multitasking to help almost everything and everyone in it’s way but it is also probably one of the greatest threat to this planet. With the help of the “Solar Dynamics Observatory” satellite scientist are able to see why it hasn’t hurt us already. The sun is always transmitting radiation, light and heat that can harm us by the slightest touch. There are a lot of eruptions from the sun that contain highly charged particles that are directed straight us but they don’t actually reach us. These eruptions are known as “Coronal mass ejection”. It consists of billions of charged particles, which are extremely hot. They travel at great speed and can cause the planet to change drastically. If the eruptions were
