Chapter : Life in the Temperate Grasslands
CBSE NCERT Solved Question Answer
Q1 What is a grassland?
Grassland can be defined as a region where grasses form the dominant type of plant life. Grasslands make up almost a quarter of the total land surface.
Q2 Name the two categories of grasslands found in the world.
World’s grasslands can be broadly categorized into: Temperate Grasslands
Tropical Grasslands THE PRARIES
Q3 What are the Prairies?
The temperate grasslands of North America are known as the Prairies. It is also known as the Sea of Grass.
Q4 Give some of the features of this area?
It is a region of flat, gently sloping or hilly land. For the most part, prairies are treeless but, near the low lying plains, flanking river valleys, woodlands can be found. Tall grass, up to two metres high, dominates the landscape. It is actually a “sea of grass”.
The prairies are bound by the Rocky Mountains in the West and the Great Lakes in the East.
Q5 Which rivers drain the Prairies?
In the USA, the grassland area is drained by the tributaries of Mississippi and the Canadian prairies are drained by the tributaries of Saskatchewan Rivers.
Q6 Name the most developed cities in the Prairies.
The important cities in the USA are Chicago, Minneapolis, Indianapolis Kansas and Denver. In Canadian prairies the important cities are Edmonton, Saskatoon, Calgary and Winnipeg.
Q7 Give an account of the climate of Prairies.
The summers are warm with temperatures of around 20°C, while in winter -20°C has been recorded in Winnipeg, Canada.
In winters a thick blanket of snow covers this region.
The annual rainfall is moderate and is ideal for the growth of grass. A local wind “Chinook” blows here.
Q8 Write a short note on the Flora and Fauna of Prairies.
Prairies are practically tree-less. Where water is available, trees such as willows, alders and poplars grow.
Places that receive rainfall of over 50 cm, are suitable for farming as the soil is fertile. Though the major crop of this area is maize, other crops including potatoes, soybean, cotton and alfa-alfa is also grown. Areas where rainfall is very little or unreliable, grasses are short and sparse. These areas are suitable for cattle rearing.
Bison or the American buffalo is the most important animal of this region. The other animals found in this region are rabbits, coyotes, gophers and Prairie dog.
Q9 What are Ranches?
Large cattle farms called ranches are looked after by sturdy men called cowboys.
Q10 Why are the Prairies known as the Granaries of the World?
The Prairies are also known as the “Granaries of the world,” due to the huge surplus of wheat production. Scientific methods of cultivation and use of tractors, harvesters and combines has made North America a surplus food producer.
Q11 Name the 2 important industries of this region.
Dairy Farming and Agriculture
Q12 What has made this region as the most industrialized region of the world?
Large mineral deposits particularly coal and iron and a good network of roads, railways and canals in this region have made it the most industrialised region in the world.
Q1 What are the Velds?
The temperate grasslands of South Africa are called the Velds.
Q2 Explain the location of the Velds.
Velds are rolling plateaus with varying heights ranging from 600 m to 1100 m. It is bound by the Drakensburg Mountains on the east. To its west lies the Kalahari Desert. The tributaries of rivers Orange and Limpopo drain the region.
Q3 Explain the climate of the Velds.
The Velds have a mild climate due to the influence of the Indian Ocean. Winters are cold and dry. Temperatures vary between 5°C and 10°C and July is the coldest month. Summers are short and warm. The Velds receive rainfall mainly in the summer months from November to February.
Q4 What kind of vegetation is found in the Velds?
The vegetation cover is sparse. Grasses dominate the landscape. Red grass grows in bush Velds. In the high Velds acacia and maroola are seen to be growing.
Q5 Name the animals commonly found in this region.
The animals of the Velds are primarily lions, leopards, cheetah and kudu.
Q6 Name the major industries of this region.
Cattle rearing along with Dairy farming and Mining
Q7 Name the most important occupations of the people living in Velds.
Sheep rearing is the most important occupation of the people. Sheep is bred mainly for wool and has given rise to the wool industry in the velds.
Q8 Name the major food crops and cash crops of this region.
Food Crops : maize, wheat, barley, oats and potato Cash Crops : tobacco, sugarcane and cotton
Q9 Write a note on mineral reserve of the Velds.
The Velds have rich reserve of minerals. Iron and steel industry has developed where coal and iron are present. Gold and diamond mining are major occupations of people of this region. Johannesburg is known for being the gold capital of the world.
Kimberley is famous for its diamond mines. Mining of diamond and gold in South Africa led to the establishment of trade ties with Britain and gradually South Africa became a British Colony. This mineral rich area has a well-developed network of transport.
