Q.2. Give geographical reasons.
1. People in monsoon region are mainly engaged in agriculture.
Ans.
People in the monsoon region mainly work in agriculture because the region has favorable climatic conditions for growing a variety of crops.
The monsoon region is located in the tropical and subtropical belt between 10° and 30°N parallels, where it receives ample sunlight throughout the year.
The summers are hot, with temperatures ranging from 27° to 32°C, while the winters are mild, with temperatures between 15° and 24°C.
The region receives rainfall during a specific season from the southwest monsoon winds, which varies between 250 to 2500 mm. Due to these conditions, agriculture is the primary occupation of people in the monsoon region.
2. Trees in equatorial forests grow tall.
Ans.
Trees in equatorial forests grow tall because of the unique conditions found in these regions.
Equatorial forests are located between 50°N and 50°S of the equator, where they receive direct sunlight year-round.
The climate is hot, and there is consistent rainfall throughout the year, typically ranging from 2500 to 3000 mm.
These conditions support the growth of dense evergreen forests, where sunlight is limited due to the dense vegetation.
As a result, trees in equatorial forests compete for sunlight and tend to grow tall.
3. Vegetation is short-lived in the Tundra region.
Ans.
The Tundra region is located between 65°N and 90°N parallels, where the climate is extremely cold.
During the brief summer period, the average temperatures range from 20°C to 30°C.
However, the harsh winter climate does not support vegetation growth.
Only short grass, small shrubs, flowers, lichen, moss, and similar plants can grow during the short summer.
As a result, the vegetation in the Tundra region has a short lifespan.
Q.3. Answer the following questions.
1. What is the latitudinal extent of the Taiga region?
Ans. Taiga region extends from 55° to 65° N latitudes from Alaska to the Atlantic coast & in parts of Eurasia.
2. Name any three herbivorous animals from the Sudan region. What has nature endowed them with for self-protection?
Ans.
Sudan region has zebras, elephant and giraffe.
Nature has gifted them with speedy legs.
The skin of the animals here have colourful spots or stripes/bands.
3. What are the characteristics of the Monsoon region?
Ans. The characteristics of the Monsoon region are as follows:
The summer temperatures range between 27° and 32°C, while the winter temperatures range from 15° to 24°C.
Rainfall in this region varies between 250 to 2500 mm, primarily received during specific seasons from the southwest monsoon.
The rainfall distribution is highly variable and uneven.
The region is home to semi-evergreen and deciduous forests, and the type of vegetation depends on the distribution of rainfall.
Agriculture is the primary occupation of the people in this region.
The Monsoon region consists of numerous small hamlets, and there are notable differences in the diet and costumes of the people.
The majority of the population in the Monsoon region is engaged in primary occupations.

Q.4. Give geographical reasons for.
1. In the hot desert region, animals like camels can survive for days without water.
Ans.
In the hot desert region, the mean summer temperature ranges from 30°C to 45°C.
The heat is intense, and rainfall is very low.
Camels have adapted to these extreme conditions. When food and water are available, camels can consume and store large amounts in their hump as fat. This allows them to survive for days without water in the hot desert region.
2. The Mediterranean region is known for its rainfall in winters.
Ans.
The Mediterranean region is located between the 30° and 40° parallels in both hemispheres on the western side of continents.
As a result, the Mediterranean region is influenced by westerlies, which bring rainfall during winters.
3. Why is the Prime Meridian considered an important meridian?
Ans.
The Taiga region has a cool climate, with summer temperatures ranging from 15°C to 20°C and winter temperatures falling below 0°C.
Mainly coniferous forests are found in this region.
The wood of the trees in the Taiga region is light and soft, making lumbering the primary occupation.
4. As one travels from the equator to the poles, the spectrum of biodiversity narrows down.
Ans.
In the equatorial region, human occupations are based on forest produce, such as gathering gum, rubber, etc.
Towards the poles, the availability of natural resources significantly affects human occupations.
The availability of sunlight and water varies from the equator to the polar region, resulting in a narrowing spectrum of biodiversity as one travels from the equator to the poles.
5. There are variations in biodiversity in different parts of the world.
Ans.
Differences in landforms, climate, and soil greatly influence flora, fauna, and human life.
These variations give rise to differences in biodiversity in different parts of the world.
6. The equatorial region has a number of diseases.
Ans. The equatorial region is prone to a number of diseases due to its hot and humid climate, which leads to the decomposition of vegetal litter.
Q.5. Answer the following question in short.
1. Describe coniferous trees in the Taiga region.
Ans. Coniferous trees in the Taiga region have light and soft wood. Their leaves are narrow and pointed. The branches of these trees tend to lean towards the ground.
2. Describe the vegetation in the Mediterranean region.
Ans. In regions with low rainfall in the Mediterranean, grass is commonly found, while mountainous areas are home to coniferous forests. Trees in the Mediterranean region have thick barks and small, thick, and oily leaves.
