2.  Vegetation is a very general term for the
plant life; it refers to the ground
cover provided by plants
 What are the factors of the growth of the
vegetation?
 The growth of vegetation depends on the
temperature, moisture. It also depends on
factors like slope and thickness of soil. There
are many soil type where plants vary from
place to place.

3.  They are classified into three major groups.
 Forests – this is where temperature and rainfall
is very high. These factors forms dense and
open forest.
 Grasslands – These grow in the region of
moderate rain.
 Shrubs – Thorny shrubs and scrubs grow in the
dry region.

5. Another name for these type of forests is
tropical rainforests.
These forests are formed in countries near
the equator and close to the tropics.
They receive hot and heavy rainfall
throughout the year.
As there is no dry season, they do not
shed their leaves.

7. Tropical deciduous forests are monsoon
forests found in the large part of
India, northern Australia and Central
America.
These forests experience seasonal
changes. So they have to shed there
leaves to conserve water.
Hardwood trees especially grow here.
These trees are used to make
furniture, transportation and construction

9. The temperate evergreen forests are
located in the mid-latitudinal coastal
region.
They are commonly found along the
eastern margin of the continents. They
contain both hard and soft wood trees.

11. They are found in the higher latitudes
The wildlife present in these are:
Deer
Fox
Wolf
Pheasant
Monal

13.  As we know that most of the east and north
east margins of the continents are covered by
temperate evergreen and deciduous trees.
The west and south west margins of the
continents are different. They have
Mediterranean vegetation.
 These regions are made in hot dry summers
and mild rainy winters. Citrus fruits such as
oranges, figs, olives and grapes. The people
have removed the natural vegetation in order
to grow such fruits.

15. In the higher latitudes of the northern
hemisphere, coniferous forests are found.
They are also called Taiga. These trees
contain softwood evergreen trees.
The uses of these trees are – the
manufacturing of paper, match boxes and
packing boxes.
The animals are: Silver foxes, mink, polar
bear which are common here.

18. Tropical grassland
 These occur in either side of the equator and
are grown in low amount of rainfall.
 The grasses which grow there are very
tall, about 3 or 4 meters in height.
 Animals which live there are:
 Elephants
 Zebra
 Giraffe
 Leopard

20. Temperate Grassland
 These are found in the mid-latitudinal zones
and in the interior part of the continents.
 The grass are very short and nutritious.

23.  These are found in the dry desert like region.
Tropical deserts are located on the western
margins of the continents. The vegetation
there is limited because of low rainfall and
scorching heat from the sun.
 If you go up to the polar regions, it gets
extremely cold. The plant life here is also
limited. Very short summers is a time for the
plants to grow.
