Water cycle is effected by pollution, whether it is water pollution or air pollution. Air is polluted by Suspended Particulate Matter and by different harmful gases like Sulphur dioxide etc. These gases react with water vapours in the sky, making the water in the clouds acidic. This acid falls as rain water causing acid rains. This acid falls in ponds, on land, in fields, causing harm to us and to the crops as well as to the fishes or creatures in water. When the water evaporates from ponds, rivers and oceans to make water vapour, the the water in these water bodies becomes more acidic, and again when acid rains occur, this acid again mixes with the water of the water bodies, which already has acid, causing the water to become more concentrated.
Answer:
D
Explanation:
The Sun because it is the friendly renewable source of energy and also it is the costless renewable source of energy
In a region that has a humid continental climate, the animals and plants living there should have some specific adaptations in order for them to survive without any bigger problem in the environment.
The animals have thicker fur which is also waterproof, in order to keep them warm, and to not allow that they are wet and heavy because of the common rains. They also tend to develop and even thicker winter coat in order for them to survive the cold snowy winters.
The plants tend to shed their leafs in the autumn as they put themselves in a hibernation mode for the cold winter, and then grow them again in the spring for the vegetative season in the coming months. They tend to be plants that manage to consume large amounts of water, but also can restrict the amount of water, as the evaporation is not as high in this parts, so they have to limit the water in order to not over-saturate themselves.
The landforms on the east and western part of the continent are very different, with the main reason being that the western part is geologically very active, while the eastern lacks geological activity.
Explanation:
The eastern part of the United States and Canada, or rather the eastern part of the North American continent, is a region that lacks geological activity for millions of years. This region can roughly be divided into two parts, one being dominated by the Appalachian Mountain Range, and the other being the plains. The Appalachians are medium high mountains, being heavily eroded, with smaller slopes, and covered with dense forests. The plains stretch along the coastline, but they are also very wide, and move several hundred of km into the mainland, making big portion of this region flat lowlands.
The western part, on the other hand, is geologically very active. There are several young mountain ranges which are still growing. There is volcanic activity, faults, and plateaus between the mountains. The coastal plains are very small and narrow. Because of the shadow effect, between the mountains there are arid zones where deserts and steppes dominate.
