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.

Explanation:
- Mechanical weathering involves the breakdown of the rocks into small pieces by the external support such as pressure whereas Chemical weathering involves the breakdown of the rocks takes place by the chemical process.
- Mechanical weathering is a physical change that is caused by the movement of wind and water whereas chemical weathering takes place when the chemicals present in the air or water get mixed with minerals or rocks.
- Mechanical weathering involves:
Abrasion, freezing, thawing, exfoliation.
- Whereas Chemical weathering involves:
dissolution, oxidation, carbonation, hydrolysis.
Answer:
Quebec enjoys the cultural independence of Canada.
Coral reefs are a very important component of the ocean’s ecosystem because they support sea life, such as crabs and sea turtles. in fact, over four thousand species depend on the survival of the reefs, which are being destroyed by bleaching. more must be done immediately to save the reefs.
development along the coastal regions has significant negative effects on coral reefs. the reefs are an essential part of the ocean’s ecosystem, and when people build structures on top of them, they are easily damaged because they are so fragile.
I’m pretty sure it’s for their horns?
