III CLIMATE AND VEGETATION – this guide gives you a concise, exam-ready overview of III CLIMATE AND VEGETATION from Class 11 Geography, written by ConceptScroll editors and reviewed against the latest NCERT textbook.
Climatic Regions of India
India’s climate can be broadly divided into six major climatic regions based on temperature and rainfall patterns: (1) Tropical Wet Climate, (2) Tropical Dry Climate, (3) Subtropical Humid Climate, (4) Mountain Climate, (5) Desert Climate, and (6) The Islands’ Climate. The Tropical Wet Climate, found in the Western Ghats and northeastern India, experiences heavy rainfall and high temperatures throughout the year, supporting evergreen forests. The Tropical Dry Climate, prevalent in the Deccan Plateau and parts of central India, has distinct wet and dry seasons with moderate rainfall. The Subtropical Humid Climate, covering the Indo-Gangetic plains, has hot summers and cool winters with moderate rainfall. Mountain Climate in the Himalayas is characterized by cold temperatures and heavy snowfall at higher altitudes. Desert Climate in Rajasthan and parts of Gujarat is marked by scanty rainfall and extreme temperatures. The Islands’ Climate, such as in the Andaman and Nicobar Islands, is tropical with high humidity and rainfall. These climatic regions dictate the type of vegetation and agricultural practices in their areas.

1.(i) (c) Abraham Ortelius was the first to consider the possibility of Europe, Africa and America having been located side by side.
(ii) (a) Polar fleeing force relates to the Revolution of the Earth.
(iii) (d) Antarctica is not a minor plate; it is a major tectonic plate.
(iv) (c) Distribution of fossils in different continents was not considered while discussing the concept of sea floor spreading.
(v) (d) The type of plate boundary of the Indian plate along the Himalayan mountains is Cont
2. Answer the following questions in about 30 words. (i) What were the forces suggested by Wegener for the movement of the continents? (ii) How are the convectional currents in the mantle initiated and maintained? (iii) What is the major difference between the transform boundary and the convergent or divergent boundaries of plates? (iv) What was the location of the Indian landmass during the formation of the Deccan Traps?
(i) Wegener suggested that the continents moved due to forces like the polar fleeing force and tidal force.
(ii) Convectional currents in the mantle are initiated by heat from the Earth's core causing mantle material to rise and fall, maintaining the currents.
(iii) Transform boundaries involve plates sliding past each other horizontally, unlike convergent or divergent boundaries where plates collide or move apart.
(iv) During the formation of the Deccan Traps, the Indian landmass was located
3. Answer the following questions in about 150 words. (i) What are the evidences in support of the continental drift theory? (ii) Bring about the basic difference between the drift theory and Plate tectonics. (iii) What were the major post-drift discoveries that rejuvenated the interest of scientists in the study of distribution of oceans and continents?
(i) Evidences supporting continental drift theory include the fit of the continents like South America and Africa, similarity of fossils across continents, matching geological formations, and paleoclimatic evidence such as glacial deposits in now tropical regions.
(ii) The drift theory proposed by Wegener suggested continents moved but lacked a mechanism. Plate tectonics explains the movement of lithospheric plates driven by mantle convection, providing a mechanism for continental drift and sea
