  • Northern Plains Have Continental Climate Because It Is Away from the Moderating Influence of the Sea
    CLIMATE IN INDIA CLASS 10 IMPORTANRT GIVE REASONS QUESTIONS Give Geographical Reasons for the following: QUESTION 1.The latitudinal extent of India is responsible for the variation in the climatic conditions which prevail in the country. Ans: The Northern plains lie to north of the Tropic of Cancer in the Temperate Zone. The winters are much colder. South India lies below the Tropic of Cancer, in the tropics and gets the direct rays of the sun. Hence it is hot through most of the year. The winters are not so cold. QUESTION 2.The Northern plains of India have a continental type of climate. Ans: Northern plains have continental climate because it is away from the moderating influence of the sea. Thus, the summers are extremely hot and winters are extremely cold. QUESTION 3.The Northern plains of India do not freeze in winter. Ans: The northern plains of India do not freeze in the winter because temperatures in this region do not fall low enough for water to freeze. One reason behind this is that the Himalayas protect the northern plains from the cold winds of Central Asia during winter. QUESTION 4.It is cooler on the mountain slopes than in the plains during summer. Ans: it is just because of the altitude .Since mountains are located at a higher altitudes that is why it is cooler where as the plains are located in lower altitude and that is the reason why is warmer . QUESTION 5:Mumbai is warmer than kanpur in December. Ans: Mumbai is warmer than kanpur in December because Mumbai is situated in a costal area and as we know that the places situated near sea it experience maritime climate and Kanpur is situated in the interior of India QUESTION 6: Though Mangalore and Mysore are on the same latitude, Mangalore experiences more rainfall than Mysore.

  • CLIMATE, FLORA and FAUNA Note: the Study Material Consists of 3 Parts
    Assignment 8 Class VIII Geography Chapter 9 INDIA : CLIMATE, FLORA AND FAUNA Note: The Study Material consists of 3 parts - ○ Part I - The important highlights of the chapter. ○ Part II - The activity based on the chapter. ○ Part III - The questions based on the study material that you need to answer in your respective notebook and submit when you are back to the school. PART I HIGHLIGHTS OF THE LESSON INTRODUCTION - CLIMATE OF INDIA The climate of a country is based on the detailed study of its temperature, rainfall, atmospheric pressure and direction of the winds. The climate of India is greatly influenced by two factors : (a) The Tropic of Cancer (232°N) – It divides India into two halves - north temperate zone ​ and the south tropical zone. (b) The Great Himalayan range from northwest to northeast direction - It separates India ​ from the rest of Asia, thus preventing the country from the bitter cold winds from Central Asia. The vast north-south extent of India 8°N to 37°N covers a distance of about 3214 km from north to south. While one can observe the unique climatic contrasts from north to south. One factor which unifies the climate of India is the fact of monsoon with alternation of seasons and reversal of winds. Therefore, the climate of India is called Tropical Monsoons. 2. FACTORS AFFECTING CLIMATE OF INDIA India experiences great variation in temperature and rainfall due to various factors affecting its climate. They are: (a) Latitude and topography (b) Influence of the Himalayas (c) Altitude (d) Distance from the sea (e) Western disturbances and tropical cyclones (1) Upper air currents and jet streams (a) Latitude and topography: The Tropic of Cancer divides India into temperate or subtropical north and tropical south.

Past shoreline signatures in the form of palaeo beach ridges in Kaveri delta (Tamil Nadu, In- dia), suggest a wave-dominated delta and thus past sea-level variations affecting directly the sedimen- tary dynamics of the Kaveri river forcing the river to either aggrade or prograde. Chronostratigraphic and foraminiferal study of the 25 m deep sediment core taken 2.5 km onshore from Tamil Nadu coast, Kaveri delta shows evidence of changing coastline over the last 150 ka. Various units in the core re- flect eight major phases of increased sea level (~3.4 ka, ~5.0 ka, 9–6 ka, 60–57 ka, 89–81 ka, ~102 ka,~121 ka and 143–140 ka) partly coinciding with the global climate cycles MIS 1, MIS 3, MIS 5, MIS 6 respectively during the late Quaternary period.
