Answer:
Mount Logan
Explanation:
Canada is a country that is roughly divided into several major geographic zones. Some of them are lowlands, while some are mountain ranges. On the eastern part of the country lies the highest point, that being Mount Logan.
Mount Logan has elevation of 5,959 meters. It is the highest peak of Canada, and the second highest on all of the North American continent. Apart from Mount Logan, there are other ten peaks that are also over 5,000 meters of elevation.
The mountain has two large glaciers on it, as apart from being very high, it is also located on very latitude, so it has perfect conditions for development and existence of glaciers.
Answer:
- The French gave the colonists money and supplies in secret.
- The Spanish closed the Port of New Orleans to the British
Explanation:
The French helped in the Revolutionary war in no small way by providing the American colonists with money and supplies. They did this in secret at first and then became more public about it such that they even sent soldiers to fight alongside the Colonists.
The Spanish also helped by closing off the port of New Orleans to the British and even using it to stage attacks against them. They did this because they were allied to France and therefore in effect, the Colonists as well.
Explanation:
Green house effect occurs when the wavelenght of the infrared radiation in the incident solar radiation, looses some of its energy on reflection from the earth surface, making it longer and unable to pass through the greenhouse gases that act like a blanket around the earth.
The reflected radiation has a longer wavelenght because it looses energy to the earth as heat; leaving it with a new wavelenght too long to go through the greenhouse gases.
The jar envoirment does not provide the earth-like material that can absorbs some of the energy of the incident radiation so it goes out with relatively the same energy. Also, the refractive index of the green house gases and the glass used in the lab might not be the same so modeling it with a glass might not produce the same effect.
Finally, the light source used might not contain enough infrared energy as an incident solar radiation.
Some of the factors would be introduction of non native species, pollution, overgrazing, chemical agents and habitat loss
