Answer: Cars that produce fossil fuels. Plastic shopping bags that use tons of plastic each year. Overfishing causes large losses of food that other organisms need. Hope this helps. :)
Still waters allow for sediments to settle down on fossils without disturbance. This gives the minerals in the sediments time to perfuse in the fossils and petrify the fossil. The sediments also settle on the fossils without disturbance, take the form of the fossil and get cemented forming molds.

Answer:
D. Increase in atmospheric Nitrogen
Explanation:
When plants undergo photosynthesis, they do not use the UV radiation that comes along with the sunlight. However, due to the UV radiation damaging plant cells and causing mutations, over time the plants evolved to have a filtering of UV light to protect themselves while they absorb sunlight.
At the same time, the photosynthesis would have increased atmospheric O2 and decreased atmospheric CO2 due to the photosynthetic process itself producing O2 and absorbing CO2. However, nitrogen is not affected by the process.
Hence, D is the answer.
Hope this helped!
