State two characteristics of Tropical deciduous forests.
Two characteristics of the Tropical Deciduous Forests are:
i. Tropical Deciduous forests shed their leaves for about six to eight months during the dry season.
ii. These forests are less dense. Based on the availability of water, these forests are categorised into moist deciduous forests and dry deciduous forests.
State two reasons why Tropical Evergreen forests are difficult to exploit.
Tropical Evergreen Forests are difficult to exploit because these forests are dense with many plants and climbers tangled to each other in these forests.
Secondly, the lack of transport means to travel deep into these forests has made their
trees difficult to be used commercially.
Identify the tree as per its characteristics mentioned below:
i. It yields wood that is hard and scented and is usually found in high altitudes.
ii. It is generally found in the deltaic region and is used to make boats.
iii. The furniture made from this tree is generally the most expensive.
i. Sandalwood
ii. Sundari
iii. Shisham
Differentiate between afforestation and deforestation. State the disadvantage of
deforestation.
Planting of trees on a large scale is known as afforestation. Deforestation refers to the large scale destruction of forests.
Disadvantages of deforestation: Since trees help in moderation of the climate, deforestation results in environmental changes like increase in temperature and reduced precipitation.
Mention two reasons why monsoon deciduous forests are commercially more valuable than the other types of forests.
i. Monsoon deciduous forests are commercially more valuable than the other types of forests because they are less dense and hence can be easily felled.
ii These forests provide valuable timber which is commercially very important.
