Greenhouse effect and atmospheric radiation?

How does the Greenhouse effect and atmospheric radiation relate to each other? I am still trying to understand the "chemistry" aspect of the greenhouse effect, not just the simple explanation. My teacher says that the GHG effect isn't really


Basically, the Greenhouse effect is when light and heat energy from the sun passes through the atmosphere and can not get out due to the greenhouse gasses, most famously, carbon dioxide. This is what happenes on Venus.

Your teacher is correct

NASA Cuts 8-Foot Hole in a 747, Bolts in Huge Telescope

Can you tear an 8-foot hole in the side of a 747 jet and have it fly not only safely but in a stable way? This isn't a terrorism-related quiz--it's a real problem that NASA tackled with its flying telescope project. The answer is a big "yes."

The telescope is a 17-ton monster called the Stratospheric Observatory for Infrared Astronomy (SOFIA) designed to make high-resolution infrared imagery of space objects, and its installation in a modified 30-year-old 747 is the culmination of a project that began over 14 years ago. The telescope was specifically engineered to fit into a jumbo, which was the largest aircraft flying at the project's inception, and it's used to make observations when the plane is flying at 40,000 feet, lower than space-based telescopes but above some of the lower-atmospheric effects of the impact ground-based telescope installations.

This is why SOFIA is a neat solution, it turns out. At ground level, IR telescopes suffer from absorption of IR wavelengths by atmospheric water, and while this problem isn't suffered if you shoot a satellite into space--you can't adjust a space-based telescope easily (or at all, possibly for decades when the Shuttle is grounded) and flying a giant telescope into orbit is both tricky and expensive.

Fuel that exhaust to the atmosphere after use, will this cause any effect to the atmospheric pressure?

Volcanic sunset 18/04/10, Helsinki Finland

As we know that gas (Exhaust gas) is much compressible than the liquid (Petrol and diesel), with so much combustion engines in our world that use petrol and diesel, this huge physical volume (Petrol and diesel) lost every days in our space, will it cause


It causes heat which excites molecules and raises atmospheric pressure, but they cool off quickly due to dilution. It is the same as pissing in the ocean; technically, it affects the atmoshere but the results are almost nil.

Does the atmospheric pressure effect the speed of sound?

Help!


Not really. The only thing that has any kind of real effect upon the speed of sound is mass and density. For example, sound travels much faster through a solid instead of gas.
