What major change occurred in the atmosphere during the precambrian?
The atmosphere, during the Precambrian became richer in oxygen caused by a bacteria called cyanobacteria.
Did the elements in the atmosphere come from the erosion of rock and outgassing?
No. Most of the atmosphere is primal - it was collected together in the accumulation that became Earth. Much of it is manufactured in stars and novae.
What is is earths evolution?
The most popular scientific theory states that earth was once a Porto planet, a planet that is like a baby. a large asteroid [left overs from the sun] soon gained gravity that pulled more asteroids towards it. in a few million years, the large asteroid will become red and be filled with lava. volcanoes erupted that formed clouds with water then water filled today's ocean. the rest of the volcanoes made large islands that became Pangaea then Pangaea becomes today's continents. of course earth developed an atmosphere then clouds formed. the first animal was a bacterial that released methane in to the atmosphere. later oxygen releasing Bacterial developed and killed the methane releasing bacterial. then fish evolved, then land animals [small] then dinosaurs, then mammals, the probably Porto humans or early humanly creatures, then homosepicans, then caveman, then today's humans.

How does the study of fossils represent the evolution of species over geological time?
The study of fossils represent the evolution of species by the time period between when they became fossils and what the ancestory line is
How did the earths atmosphere change composition to become todays nitrogen and oxygen atmosphere?
your question is... How did the Earth`s atmosphere change composotion to became today`s nitrogen and oxygen atmosphere? Answer: it happend with the help of solar untraviolet (uv) radiation,the very thing what we worry about now for its cancer-causing ability

The Earth would start to heat up and the ocean would evaporate.
Did Apollo 13 dock with anything in space?

What is a form of macro evolution?
Macro evolution is just speciation, so you are a form of macro evolution. We and the chimpanzees have a common ancestor that we split from about 6 million years ago. We became Homo sapiensand they became Pan troglodytes.
How evolution affects you?
That's how the human race became what it is.

When did meteorites form within the solar system?
probably a Little bit after the sun formed. the sun gravity pulled dust into orbit and the dust clumped to geather and some became bigger to form proto planets but others stayed the same and became asteroid NOT a meteorite a .meteorite is in earths atmosphere a asteroid is in space. did this help?
Who developed the ideas that became known as the theory of evolution by natural selection?
The answer is: Darwin
What planet lost its atmosphere and became a barren wasteland?
Mercury
Which substance was not present in Earth's primitive atmosphere?
Oxygen was not found in the atmosphere of primitive Earth. It is so reactive that it became locked up in compounds at the time of Earths formation. These compounds were varied, but the bulk of them were mineral oxides, silicates, carbon dioxide and water. Free oxygen entered the atmosphere only after the development of blue-green algae, which produced oxygen from carbon dioxide.
