A geostationary orbit achieved by being in a location where the satellite's orbital period is 24 hours. This means the satellite is about 36,000 km (22,000 miles) above the Earth's surface. All orbits must therefore be over the equator. Every orbit around the earth looks like a circular (or elliptical) ring whose center (or one foci) is at the center of gravity of the Earth. An orbit exactly above the equator is one such orbit, but any orbit can be tilted as long as the center (or focus) stays at the Earth's center and the whole orbit is flat like a disk. On various NASA maps this makes the orbit look like a sinewave, but on a globe it stays a flat circle (or ellipse). On "Star Trek" I have seen errors a number of times on "Geostationary orbit over the North Pole", well you can't do that. Likewise, a "Lunar-stationary orbit" is impossible for a spacecraft, since Earth itself is already IN THE STATIONARY ORBIT POSITION! Remember that a geostationary orbit looks like it is always over the same spot on the Earth (or other body). If you were on the Moon, the Earth would be in the same position in the sky at all times.
A geostationary satellite does not trace a path over the surface of the earth because that is what geostationary means - the satellite is stationary over a point on the Earth.
What do you mean "dirty"? A vanishingly small trace of all water on Earth is chemically pure; even water that's naturally clean enough to drink (some springs, rainfall) has trace amounts of contaminants in it. By that standard, 100% of Earth's water is "dirty".
Trace is a verb and a noun.Verb: The boy traced the picture.Noun: The ship disappeared without a trace.
The atmosphere is a thin layer of gases surrounding Earth which includes nitrogen, oxygen, argon, carbon dioxide and a trace amount of other gases.
It can be, meaning rarely occurring, or present in small amounts, as in trace minerals. But it is also used as a noun (e.g. without a trace) and used differently as a verb (to trace meaning to follow, trail, pursue, or locate, or to draw by copying from an original).
A geostationary satellite does not trace a path over the surface of the earth because that is what geostationary means - the satellite is stationary over a point on the Earth.
Earth is the third planet from the Sun in our solar system. It has one natural satellite, the Moon. Earth's atmosphere is composed of 78% nitrogen, 21% oxygen, and trace amounts of other gases. The planet's surface is about 71% water, mostly in the form of oceans. Earth is the only known planet to support life.
Water evaporates from Earth's surface into the atmosphere, forming clouds. These clouds then release precipitation in the form of rain or snow, which returns water to Earth's surface. Some of this water is absorbed by the ground, while some flows back into rivers, lakes, and oceans, starting the cycle again.
The Earth's atmosphere within 10 km of the surface contains approximately 78% nitrogen, 21% oxygen, and the remaining 1% is made up of trace gases such as argon, carbon dioxide, neon, helium, and methane.

You're describing the wavelike line that shows up on the maps at mission control when theyplot the path of the spacecraft that they've just launched.Try to imagine this:The satellite is circling the earth at a constant rate ... say one orbit every couple of hours. At the same time,the earth is rotating under the satellite, one complete spin every 24 hours.Add these two motions together, and you'll see that a point on the ground ... if it always stays directly UNDERthe satellite ... will trace that 'wave' shape on the ground.
Imagine firing a handgun while standing on earth with no one or thing around for the bullet to hit. The bullet will speed out of the gun, and as it moves it will trace out a curve as it gradually gets pulled to earth by the earth's gravity, and loses speed because of air resistance. It wil then fall to earth perhaps several hundred yards away. Now imagine climbing up a tall tower and doing the same thing with a high velocity rifle. The bullet will travel faster from the rifle than from the handgun but will still eventually fall to the ground under gravity and slow down because of air resistance, but in this case, the bullet might travel a mile or two before falling to the ground, and the curve its path of flight traces out will be much larger. Now imagine the satellite. When launched, the satellite travels fast like the bullet, but it will not slow down like the bullet because, as the satellite is launched into space, there is no air resistance as there is no air there. Similarly the speed at which the satellite is launched is sufficient for it to continue to fall to earth, just like the bullet, but in the satellite's case the curve it traces out is exactly the same as the curve of the earth. So, the satellite continues to freefall to earth, just like the bullets, but as the curve of the earth is exactly the same as the curve of the satellite's path, the satellite will never reach the earth. It's as if the earth was 'moving away' from the satellite as fast as it was falling towards it. This is what is meant by 'going into orbit' and it is why satellites and spacecraft have to escape the earth at great speed if they are to go into orbit. If they did not have the speed required (called the 'escape velocity') their curve of trajectory would be too small and they would fall back to earth before going into orbit.
Faults are planar fractures in Earth's crust where one side has moved relative to the other. They can vary in size, orientation, and shape. Faults often exhibit a linear feature called a fault trace on the Earth's surface.
The conditions are not so much geographical as they are geological. Since diamonds are erupted to the earth's surface by a specific type of volcanism with other trace minerals, geologists look for these trace minerals. Kimberlite is a rock produced by this type of volcanism, and is where diamonds are found in, or eroded from. Only about one in 200 kimberlite-trace-mineral sites include diamonds.

No, carbon dioxide is not considered a trace gas in Earth's atmosphere. Trace gases are typically present in very small concentrations compared to major atmospheric gases like nitrogen and oxygen. Carbon dioxide, while not a trace gas, is an important greenhouse gas that plays a key role in regulating Earth's climate.
An increase in skin cancer can be traced to a decrease in atmospheric ozone. Ozone protects the Earth's surface by absorbing harmful ultraviolet radiation from the sun, which can cause skin cancer when it reaches the Earth's surface in excessive amounts.
