North America is located on the northern hemisphere.
and also in the western hemisphere
In the west of the continent, there is Bering Strait separating it from Asia.
For the Natural Vegetation of North America.
The first one we called Tundra.
This type of Natural Vegetation can be found at polar latitudes,
in the cold climatic zone of the North America.
These type of Vegetation includes: Lichens, Mosses, Flowering Herbs and Dwarf Shrubs.
The Tundra ecosystem is considered one of - the most fragile ecosystem.
as the vegetation takes a long time to - recover after it has been disturbed.
for the Coniferous forest the second one,
Farther south in the high latitudes of - the North American continent,
the main natural vegetation is Coniferous forest. Sometimes called Taiga or Boreal forest,
There are the trees with needle-like leaves,
such as spruce, fir and pine.
Taiga covers large areas of Alaska and Canada.
Here the growing period is short and precipitation is relatively low.
The third one, Deciduous forest.
Towards the mid-latitude of the North American Continent -
lies a broad zone of mixed coniferous and deciduous forests.
There are the broad-leaved deciduous trees such as:
Oak,
Birch,
Cedar,
Maple,
Elm,
Beech,
and Ash to grow.
There trees shed their leaves in autumn, that is just before winter begins.
Temperate Grassland.
In the drier regions of the mid-latitudes, forests give way to grasslands.
Here, in the dry mid-latitude climate of the continental interior,
There are treeless grassy plains.
They provide rich agricultural land for the growing of crops such as wheat.
The Steppes, where the grass is shorter,
is more suitable for animals to graze.
the predominant natural vegetation is tropical grassland,
Hot Desssert Vegetation.
There are located in the hot subtropical and tropical climatic zones,
The extremely high daytime temperatures
and the prolonged drought conditions of the hot deserts
result in the growth of short thorny shrubs and coarse grasses.
There are such as: cactus,
have developed characteristics to enable them to adapt
to the perpetually hot and dry climate.
Tropical Grassland.
Between 50 and 150 North,
which is the product of the distinct wet and dry seasons.
The low rainfall cannot support full tree cover.
So, there are covered by tall grasses land.
Giving it a 'parkland' appearance.
Tropical Forests.
Nearer to the Equator, tropical forests occupy
the tropical climatic zone of North America.
There are in the Central America and West Indies.
The coastal areas of these regions have mangrove forests.
Geological Features.
Low ancient mountain.
In North America, there is a structure of old rocks
called the Canadian or Laurentian rock zone,
which is in the stone age of Cambrian and the old rock zone of the continents.
The zone covers the area the northeastern part of Canada,
and the island in Hudson Bay including Greenland,
and the plateaus lying in a long line from Newfoundland
in the northeast of Canada to Georgia,
the southeast of the United States of America.
Steep young mountain ranges.
The young mountain ranges can be found
the western part of the North American continent.
They consist of high and complex mountain
ranges extending from the northwestern part
of the continent around Bering Strait
to the southwestern part and joins the Andes in South America.
Plains.
In the middle of the North American continent
is a big plain spreading from Arctic Ocean to the Gulf of Mexico.
The plains are gently undulating.
The most important plain is the Great Plains,
the plain surrounding Hudson Bay and Mississippi plain.
Peninsulas.
There are several peninsulas in North America.
Along the west coast are the Alaska peninsula,
Baja California
and Florida
can be found on the east coast.
The Yucatan peninsula is in the Gulf of Mexico.
There are many rivers cutting across the plains.
Most of them originate from the mountains in the west and east.
These rivers from the tributaries of the Mississippi-Mossouri river system.
