Answer: I think the correct answer is E) none of the above.
Explanation:
The answer is pollen. It has been left in lake sediments throughout hundreds of years, allowing us to gain a better understanding of climate change and its effects on the Great Lakes during the Ice Age.
I hope this helps! :)
Answer: incomplete question.
Explanation:
b. At higher elevations, it would take longer to hard boil an egg, because there is a lower boiling point, so the egg is boiling in water at a lower temperature.
Explanation:
The best answer from the given choices is that, at higher elevations, it would take longer to hard boil an egg, because there is a lower boiling point,
so the egg is boiling in water at a lower temperature.
- Boiling point is simply the pressure at which the vapor pressure of a liquid is equal to the atmospheric pressure.
- At higher elevations, the atmospheric pressure is low and it would require little heat to boil water and turn it into vapor.
- To hard boil an egg, we need elevated temperature.
- But since water to use hard boiling has an unusually low temperature, it becomes more difficult since much of the water turns into vapor.
- This is why at higher elevations, it takes a longer time to hard boil eggs.
