Ans:

Forests and Grasslands	Description
	Tropical Evergreen Forests: Tropical rain forests are another name for these types of forests. These dense woodlands can be found near the equator and near the tropics. Rosewood, Ebony, and Mahogany are among the trees found here.
	Tropical Deciduous Forests: Monsoon forests can be found in extensive parts of India, northern Australia, and Central America, and are classified as tropical deciduous forests. Seasonal changes occur in certain areas. Teak, Neem and Shisham are some of the trees found in these forests.
	Temperate Evergreen Forests:  The temperate evergreen forests are found in the coastal region's mid-latitudinal zone. They are usually found along the continents' eastern edges. Oak and pine trees can be found here.
	Temperate Deciduous Forests: There are more temperate deciduous forests as we move to higher latitudes. These can be found in the northeastern United States, China, New Zealand, Chile, and western European coastal regions. During the dry season, they drop their leaves. Oak, Ash, and Beech are some of the trees that may be found here.
	Grasslands:  These can be found on both sides of the equator and reach all the way to the tropics. These plants can be found in locations with moderate to low rainfall.
	Coniferous Forests:  The beautiful Coniferous woods of the Northern Hemisphere can be found at higher latitudes (500-700). Taiga is another name for these. These forests can also be found at greater elevations. Important tree species found here include Chir, Pine, and Cedar.

In Text Questions

1. Now can you tell why Salima saw changes in the natural vegetation as she climbed higher and higher? What type of vegetation did she see in the Himalayas starting with the foothills and going to the higher altitudes?

Ans: As Salima went higher and higher, she noticed variations in the natural vegetation due to changes in altitude and related climatic factors such as temperature, precipitation, low air density, and soil form. Salima noticed thick jungles of Sal and Teak in the hillsides. On the mountain slopes, she could see coniferous trees such as Pines as she climbed higher. She also discovered an area covered with short grass and snow at higher elevations.

Important Points to Remember

Some important points related to NCERT Class 7 Social Science (Geography) - Our Environment Chapter-6 are as follows.

• Generally, natural vegetation is classified into three broad categories. These categories are forest, grassland and shrubs.

(a) Forests: Forest is developed in an environment where temperature and rainfall are plentiful to support tree cover. 

(b) Grasslands: Grasslands grow in the region of moderate rain.

(c) Shrubs: Thorny shrubs and scrubs require the dry region to grow.

• Tropical Evergreen Forests are also called tropical rainforests. They grow in the hot regions near the equator and close to the tropics where heavy rainfall occurs throughout the year. The common trees of this forest are rosewood, ebony, mahogany, etc.

• Temperature Evergreen forests are found in the mid latitudinal coastal region. They are commonly located along the eastern margin of the continents, e.g. In South-East Brazil, South China and in the southeast USA.

• Tropical Deciduous Forests are found in a large part of northern Australia, India and Central America because these regions face seasonal changes throughout the year. They are the monsoon forests. These regions experience seasonal changes.

• Temperate deciduous forests are usually seen in regions having moist and warm summers and cold winters. The trees in temperate deciduous forests shed their leaves each year.

• A coniferous forest comprises evergreen trees that bear cones. Elegant pines, spruce, fir, and tamarack grow in this biome. In most of the northern forests, the coniferous trees merge with deciduous trees, particularly aspen, birch, sugar maple, and basswood.

• The two important factors for the growth of vegetation are temperature and moisture.
