Comets, because they are made from ice and dirt.
Scientists study the mantle indirectly by analyzing seismic waves from earthquakes, studying volcanic eruptions, and examining rock samples brought to the surface by volcanic activity. By combining these methods, scientists can gain valuable insights into the composition, temperature, and behavior of the Earth's mantle.
Crude oil is brought to the Earth's surface through drilling wells into underground oil reservoirs. Once a well is drilled, a combination of pressure from the reservoir and assistance from pumps is used to bring the crude oil to the surface for processing and refining.
Height above earths surface is called elevation
Resources are typically brought up from under Earth's surface through processes like drilling, mining, and extraction. Drilling involves creating a borehole to reach oil or gas deposits, mining involves excavating minerals from the ground, and extraction involves pumping out fluids such as water or geothermal energy.
The Earth's surface layer is called the crust.
We do not have a definitive answer to this question. Scientists are still researching this question as of 2015. However, if extraterrestrial, it certainly was not ONE extraterrestrial body.

nitrogen is brought to earths surface by the gravitational pull of zero gravity
pressure from the heat under the earths surface

well, it does. haven't you ever heard of hot lava? that's magma rising from the surface.

Comets, many scientists believe. A few, such as British astronomer Sir Fred Hoyle, believed that perhaps organic molecules may have even brought life itself to the Earth in the early days of our planet. This hypothesis, called "panspermia", suggests that the universe might be filled with life spread from only one or a few original locations. So far, this is only an idea; there is no evidence at all to support it. However, since we have conducted only the most cursory examination of a couple of planets and moons in this one solar system, it cannot be completely discounted.
