North America Outline

This biome is located in the northern part of the Northern Hemisphere and is in North America, Asia, and Europe. It stretches across Alaska, Canada, Scandinavia, and Russia spreading through the Northern

Temperature contrast between the equator and the Arctic region is greatest in the winter. Temperatures near or at the equator only change a few degrees between winter and summer while the Arctic region changes drastically up to 40 degrees between the seasons.

1.The geological and geographical conditions that set the stage for North American history is that the earth formed slowly,10 million years ago North America was sculpted ,and the continent was anchored in a north eastern corner by a canadian shield.Around 2 million years ago the great ice age began,the ice sheets were about 2 miles thick crept from the polar region , in North America the glaciers carpeted most of canada and the U.S., parts of europe,Asia,and the americas werecovered with a blanket of snow.

About 225 million years ago, according to the theory of “Pangaea,” the world was once a single supercontinent that contained all the dry land. Approximately 10 million years ago, North America was shaped by the majestic Canadian Shield. About 2 million years ago, in North America, the grand glaciers laid the land of Canada and the United States, southbound as far as from Pennsylvania all the way to the Pacific Northwest. Recently, about 135 million to 25 million years ago, four massive ranges—the Rockies, the Sierra Nevada, the Cascades, and the Coast Ranges, arose in western North America. About 35000 years ago, the ancestors of the Native Americans, the nomadic Asian hunters, first

Canada is the largest North American continent by land area. It is also the second-largest country in the world in terms of land area. Canada is home to 35 million people. It borders the United States. Ottawa is the capital of Canada. It is also the fifth most populous city in Canada.

During the Ice Age, the water froze into massive glaciers and exposed a land bridge that connected Eurasia and North America.

Plant life tends to be of low growth and, during the short summer, the birds arrive in large numbers to feed on the insects that are born in this period. The climate is cold summers and very cold winters characterize the tundra area in the northern most limit plant growth. Areas

people of this region are known as being farmers. Although there are many non-farmers in this

In the north, the climate typically consists of hot and humid summers and mild to very severe winters. These severe winters result in freezing temperatures,

America was named after Amerigo Vespucci, the navigator that discovered it. Due to the American Civil War, it was divided into North America and South America. Although these are now two different continents, they are still similar in a way. They have different people, with different cultures. Yet, their physical features and the impact these people have on the lands resemble each other in a

The United States and Mexico together take up the majority of the habitable lands of North America. In 1763, the Viceroyalty of New Spain controlled most of

There were some who used the South Pacific Ocean islands and then the North Pacific Ocean islands to reach the American Continent.

In the northern part of the earth and the upper slopes of all mountains all over the world, a unique biome called tundra exists. Tundra is one of the coldest and harshest biomes of the world. The winters are long and cold, and the summers are short and cool. Tundra is far from the equator; therefore, Tundra soil is generally poor in nutrients. Since the biome is covered in snow throughout the year, the arctic tundra doesn’t seem like a place where plants and animals can survive. Yet, plants and animals are able to survive, thanks to their special adaptations. In fact, it isn’t the freezing temperature that they fear; it is us, human. Today, tundra faces lots of threats and problems because of human. One of the major problem is Global

north pole and the arctic circle, because of the Global warming the ice is melting and the

Permafrost comprises 24% of the land in the Northern hemisphere, and stores massive amounts of carbon. It is a permanent frozen soil that remains at or below 0 degrees Celsius continuously for at least two consecutive years. Even though the soil is frozen, plants still grow in the soil at the surface which is not frozen during the warmer parts of the year. As Figure 1 shows, permafrost has different layers; the active layer is ground that is
