Can you describe the atmosphere and the inside of the Earth?

Answer 1

The Earth was formed about 4.6 billion years ago. Since then its material has differentiated into layers. The central core which is very hot and dense has solidified and consists of iron and nickle metals. Above this is a solid rock mantle, and then a thin crust made up of many different types of rocks and minerals, predominantly silicate rock. The crust is broken into several large, solid plates and some smaller ones. These plates float on partly molten underlying mantle material. Earth's continents, oceans, fresh water, and atmosphere all support life.

Earth's atmosphere consists of a layer of gas which is rich in nitrogen, oxygen, carbon dioxide, and a mixture of other minor gases including ozone high in the upper levels. The Earth's atmosphere reaches all the way up to about 310 miles above the surface, however the majority of the gases (thickest concentration) lie within 10 miles of the surface (within roughly 50,000 feet of the surface). Heat from the Sun warms the surface of the Earth and its atmosphere unevenly and winds develop as a result. Winds drive the air and moisture all over the planet. The atmosphere is 78 percent nitrogen, 21 percent oxygen, and 1 percent argon and trace gases. Water vapor in Earth's air varies from 0 to 4 percent.

Answer 2

Thrusters do no longer choose air. they do no longer choose the oxygen in it for combustion as a results of fact they convey their own oxygen with them. they do no longer choose air to "push" against as a results of undeniable fact that may no longer how rockets paintings; they paintings by potential of organic Newtonian reaction. Airplanes do no longer strictly choose a fluid medium. Airplanes are purely anticipated purely to paintings in this kind of medium, so their administration structures are designed to capitalize on the presence of that medium. whilst the gap return and forth is working interior the air, it makes use of that air. It has wings, a rudder, and mixed elevator-aileron surfaces purely like different airplanes. mutually as the gap return and forth does have thrusters, and mutually as those thrusters could paintings relatively effectively interior the air, the aerodynamic administration surfaces paintings extra suited. Airliners have purely the administration surfaces as a results of fact they're under no circumstances meant to flow away the ambience. subsequently they are in a position to assume the ambience to be there whilst they choose it, and use purely aerodynamic administration surfaces. no longer something prevents you from attaching thruster programs to an airliner and taking it into area, the place it may then be waiting to instruction manual purely to boot as a results of fact the return and forth. it relatively is like asserting that if a river boat desires a paddle-wheel, how can a truck paintings on land and not employing a paddle-wheel. The truck won't paintings interior the water as a results of fact it wasn't meant to, and its fashion designer provided purely locomotion suited to its meant environment. The river boat won't paintings on land as a results of fact its fashion designer meant for it purely to paintings interior the water and in addition provided a sturdy potential of administration for that environment. the gap return and forth is one among an fairly few automobiles it is, to warp the analogy, the two a truck and a river boat. for this reason it has the two forms of administration structures.

There is a good article, which will answer your questions on the earth, from Wikipedia, the free, online encyclopedia:
