Why do objects burn while entering from outer space to Earth's atmosphere?
Why do objects in space entering the Earth’s atmosphere catch fire?
Why isn't fire attracted by the Earth's gravity when you fire any object? Why does the fire always go upwards? Can there be fire in space? If we were to build a pipe so long starting from the Earth and into outer space, (use your imagination) would the air from the Earth's atmosphere leak out into space? And, if not, what would happen? What keeps life sustaining gas in our atmosphere? Why can't they just escape to the outer space? Why don't we load the earths trash on earth and launch it into space or toward the sun? What is the atmosphere like in space? Why does a flame go upward despite gravity? Why don't the metals on satellites and rockets boil away when we send them into space since there is no pressure in the vacuum of space? What happens when lightning strikes the oceans surface? How are nearby organisms affected by it? Earth (planet): Why don't we fall directly in the earth from space? What would happen if a fire on the ISS opened out to outer space? If the earth and its atmosphere were to disappear, what would happen to objects in orbit, such as satellites and the moon? Why can’t an airplane just fly into space? What is the reason why gases deviate from ideal behavior? Why is air not visible? When we breathe air do we breathe other gases as well and if do then what happens to those harmful gases? Why don't we launch trash into space? Would a planet’s inhabitants be able to survive if its atmosphere – due to some or the other reason – created its own light? When an aircraft dumps fuel, what happens to it? Does it always evaporate before reaching the ground? What do explosions look like in space? What does an explosion in space look like? Why does air flow? What would happen to a flame inside the space station? Would a person floating in outer space explode due to lack of atmospheric pressure? What would happen if  the Earth and all terrestrial objects suddenly  stopped spinning, but the atmosphere retained its velocity? Hypothetically, is it possible to light fire in outer space? As we convert solid (coal) and liquid (oil) fuels into gases through combustion, does the volume of the Earth's atmosphere expand? In other words, are we pushing the molecules in the upper atmosphere even further away? What would earth be like if the ocean was flammable? How are different atmospheres affected by cosmic rays? What states of matter are fire and lightning?
