Meaning of Global Warning A gradual increase in the overall temperature of the earth’s atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide‚ CFCs‚ and other pollutants. Climate change is any substantial change in Earth’s climate that lasts for an extended period of time. Global warming refers to climate change that causes an increase in the average temperature of the lower atmosphere. Global warming can have many different causes‚ but it is most

Frozen tundras‚ green forests‚ and flat rolling plains are all unique features of North America. Three different post-columbian groups thrived in these geographical regions by developing ways of survival. I will be talking about the Iroquois in the Eastern Woodlands‚ the Cheyenne in the Great Plains‚ and the Inuit from the Arctic/Sub-Arctic. First‚ the Eastern Woodlands has rich dirt which makes it perfect for farming‚ and the Iroquois tribe were the best farmers there were in the Eastern Woodlands

A report in 2013 states that‚ human is the main cause of the Global warming which lead to the reduction in snow in Antarctic and Arctic regions‚ which paved way to the increase in the sea level. This effect will include increase in sea level‚ expansion of subtropical Deserts. Warming is expected to be higher in the Arctic regions. This has a lot of effects which will create lot of changes in human life; like heavy rainfall‚ heat waves‚ ocean acidification‚ and extinction of

A: An ecosystem is a natural unit consisting of all plants‚ animals and micro-organisms in an area functioning together with all the non-living physical factors of the environment. Among terrestrial ecosystems‚ the type that provides the most appropriate scale for understanding world distribution pattern is called a biome. Q2: What is an ecotone

Landscape – is a large land area covering many square kilometers composed of interacting ecosystem. 9 major biomes in the terrestrial biomes 1. Tundra – also called arctic tundra occurs in extreme northern latitudes wherever snow melts seasonally. 2. Taiga – Is the evergreen forest of the north.

The Tropical Desert gets less than twenty-five centimeters of rain yearly. Since this is a desert‚ it has very poor soil quality and temperatures ranging from 61-120 degrees. Many animals live in this type of biome‚

Outline the relationship between climate and one or more biomes. (10 marks). One biome which is part of the cold zone of the Earth where the latitude of the sun is from 60-90° is Tundra. Tundra is a treeless‚ level‚ or gently undulating plain characteristic of the Artic and sub-Artic regions characterised by low temperatures and short growing seasons. The polar areas between 60 and 90° latitude receive less heat from solar radiation as the angle of the sun is at a much lower angle towards the ground
