CLASSIFICATIONS OF FOREST
BOREAL FOREST- have
one layer of 20-meter trees.
These forest are usually found
if Northern Asia, Europe and
America.
![Page 9: Economics me](https://reader036.fdocuments.in/reader036/viewer/2022070318/55749ee1d8b42a66438b4fe7/html5/thumbnails/9.jpg)
TEMPERATE DECIDUOUS
FOREST- consists mainly of
broadleaf deciduous trees with
shrub and herb layers growing on
fertile soil. These forest are
usually found in Europe and in
parts of East Asia.
![Page 10: Economics me](https://reader036.fdocuments.in/reader036/viewer/2022070318/55749ee1d8b42a66438b4fe7/html5/thumbnails/10.jpg)
TEMPERATURE EVERGREEN
FORESTS- consist of needle leaf,
redwood, and eucalyptus trees , as
well as liverworts and ferns. These
are usually found in North and South
America, as well as pacific, where
they are home to native flora and
fauna.
![Page 11: Economics me](https://reader036.fdocuments.in/reader036/viewer/2022070318/55749ee1d8b42a66438b4fe7/html5/thumbnails/11.jpg)
MEDITERRANEAN FOREST-
consist mainly of evergreen oaks
and laurels and thrive in moist
winter and hot summers. Aside
from Mediterranean these types
of forest are also found in Africa
and Australia.
![Page 12: Economics me](https://reader036.fdocuments.in/reader036/viewer/2022070318/55749ee1d8b42a66438b4fe7/html5/thumbnails/12.jpg)
TROPICAL RAINFOREST- have
a wide array of trees, but mostly
broadleaf evergreens , with
shrubs, herbs and climbing
plants. Most tropical forest are
found in almost all parts of the
world.
![Page 13: Economics me](https://reader036.fdocuments.in/reader036/viewer/2022070318/55749ee1d8b42a66438b4fe7/html5/thumbnails/13.jpg)
TROPICAL SEASONAL
FOREST- also consist of variety of
trees, most are deciduous trees,
including bamboos and palms.
These forest are commonly found
in almost all parts of the world.
![Page 14: Economics me](https://reader036.fdocuments.in/reader036/viewer/2022070318/55749ee1d8b42a66438b4fe7/html5/thumbnails/14.jpg)
SAVANNAS- are found where
trees are widely spaced, and
where most of the grounds are
covered shrubs, herbs, and
grasses, which is why they are
mistaken for grasslands. These
are mainly found in Africa.
![Page 15: Economics me](https://reader036.fdocuments.in/reader036/viewer/2022070318/55749ee1d8b42a66438b4fe7/html5/thumbnails/15.jpg)
MOUNTAIN FOREST- consist
of deciduous, needle leaf, and
pines. Deer, bears, and panda

which found in the mountains
of Europe and Asia.
![Page 16: Economics me](https://reader036.fdocuments.in/reader036/viewer/2022070318/55749ee1d8b42a66438b4fe7/html5/thumbnails/16.jpg)

It is the destruction of forests for
human needs without corresponding
replacement of lost trees. These leads
to soil erosion, drought, flooding, loss
of wildlife, as well as worsening
greenhouse effect, as fewer trees can
absorb carbon dioxide from the air.
![Page 18: Economics me](https://reader036.fdocuments.in/reader036/viewer/2022070318/55749ee1d8b42a66438b4fe7/html5/thumbnails/18.jpg)

These resources that cannot be
replaced anymore.
There is a need to use them
efficiently. Because it takes a very
long time for this minerals to form.
They are being used faster than
they can form.
![Page 30: Economics me](https://reader036.fdocuments.in/reader036/viewer/2022070318/55749ee1d8b42a66438b4fe7/html5/thumbnails/30.jpg)

A kind of rock that can be burned
to produce heat and energy. Coal
comes from the remains of plants
that died millions of years ago, and
formed thick layers of matter
which eventually developed into
rocks. This is why it is called fossil
fuel.
![Page 32: Economics me](https://reader036.fdocuments.in/reader036/viewer/2022070318/55749ee1d8b42a66438b4fe7/html5/thumbnails/32.jpg)

power plants.
To produce coke for the
manufacture of steel.
