Essay-type Question-Answers
1. Describe the Continental Drift Theory briefly. HSLC ’18, ’22
Ans: According to the Continental Drift Theory, about 300 million years ago, all the landmasses of the earth were united into a single supercontinent called “Pangaea,” surrounded by a vast ocean called “Panthalassa.” Over time, a narrow sea called the “Tethys Sea” developed, dividing Pangaea into two parts—Laurasia in the north and Gondwanaland in the south.
About 250 million years ago, due to crustal movements and continental drift, these landmasses further broke apart and moved to their present positions. Laurasia split into North America, Greenland, Europe, and Asia, while Gondwanaland split into South America, Africa, Madagascar, India, Arabia, Malaysia, Australia, and Antarctica.
2. Write briefly about the relief features of the ocean floor.
Ans: The ocean floor is uneven, just like the land surface. It consists of ridges, trenches, plateaus, and plains. The average depth of oceans is about 4000 meters. From the continental margin towards the deep ocean, depth gradually increases. Major features include continental shelf, continental slope, deep-sea plains, mid-ocean ridges, and islands. The continental shelf extends up to about 200 meters depth near the coast.
3. Briefly describe the distribution of continents and oceans. HSLC’20, ’23
Ans: The land-covered part of the earth is called the lithosphere, while thewater-covered part including oceans, seas, rivers, and lakes is called the hydrosphere. About 29% of the earth’s surface is land and 71% is water. Continents and oceans are interrelated and interconnected. Most oceans are connected to each other, while landmasses are divided into major continental groups:
(i) Asia, Europe, and Africa, (ii) North and South America, (iii)Australia and surrounding islands (Oceania). Asia is the largest continent and the Pacific Ocean is the largest ocean.
4. Discuss the natural features of Asia. HSLC ’20, ’23
Ans: Asia can be divided into eight physical divisions:
(1) Northern plains
(2) Central mountainous and plateau region
(3) Western plateau region
(4) Southern plateau region
(5) Eastern mountainous region
(6) River valley regions
(7) Coastal regions
(8) Islands
Each region has distinct features such as fertile river valleys, high plateaus like the Pamir, desert regions, and extensive coastal and island systems.
5. Answer with reasons:
(a) Why is about 90% of the world’s population concentrated in the Northern Hemisphere?
Ans: Because most of the Earth’s landmass is located in the Northern Hemisphere, making it more suitable for human settlement.
(b) Why is the climate of Asia diverse? HSLC ’17
Ans: Asia has a vast size and extends from the equator to the polar regions. Its location, relief features, distance from the sea, monsoon winds, and other climatic factors cause great climatic diversity.
(c) Why is there no permanent human settlement in Antarctica?
Ans: Antarctica is covered with ice throughout most of the year and experiences extreme cold with six months of day and six months of night, making permanent human settlement impossible.
6. What factors influence agriculture in Asia? HSLC ’15
Ans: The main factor influencing agriculture in Asia is climate. Adequate rainfall, fertile soil, and flat land are essential for agriculture. Asia has all these conditions. Crops like rice, wheat, cotton, sugarcane, and spices are widely grown in different regions.
7. Give an account of the distribution and use of natural resources in Asia. HSLC ’15
Ans: Asia is rich in natural resources:
(a) Land resources: About 31% of the world’s agricultural land is in Asia, especially in river valleys and deltas.
(b) Water resources: Used for electricity generation and transport. Asia ranks second in power generation.
(c) Forest resources: Rich in diverse vegetation and medicinal plants.
(d) Mineral resources: Includes petroleum, natural gas, and various minerals, especially in the Middle East.
8. Name five countries of Europe with their capitals. HSLC ’17

Ans: North America is a large continent in the Northern Hemisphere with an area of about 24.3 million sq. km. Its highest point is Mount McKinley and its lowest is Death Valley. It has varied physical features divided into four regions: Rocky Mountains, Great Plains, Appalachian Highlands, and Coastal
Plains.
10. Write briefly about the surface features of the earth. HSLC ’19
Ans: The earth’s surface consists of the lithosphere (land) and hydrosphere(water). These are interconnected and distributed unevenly. Land covers about 29% and water about 71% of the earth’s surface. Continents are grouped into major landmasses, while oceans form a continuous interconnected body of water.
