Oceans and Continents – this guide gives you a concise, exam-ready overview of Oceans and Continents from Class 6 Social Science, written by ConceptScroll editors and reviewed against the latest NCERT textbook.
Islands
Islands are smaller landmasses surrounded by water on all sides. Unlike continents, which are very large, islands vary greatly in size from tiny islets to large land areas. There are lakhs (hundreds of thousands) of islands on Earth. Greenland is the largest island in the world, larger than the combined areas of the ten largest states of India. India itself has more than 1,300 islands, including two major groups: the Andaman and Nicobar Islands in the Bay of Bengal and the Lakshadweep Islands in the Arabian Sea. Antarctica, while largely covered by ice, is a continent explored by India since 1981 under the Indian Antarctica Programme. India has established scientific research stations there, such as 'Dakshin Gangotri.' Islands and continents are both surrounded by water, but continents are not considered islands due to their vast size.
📊 Diagram: Fig. 2.4 (on the right). This map of India is the same as Fig. 1.6, but with the addition of the Arabian Sea and the Bay of Bengal. Also marked are India's two major groups of islands.
🧪 Activity: Locate and mark the major island groups of India on the map and discuss the difference between islands and continents.
🔗 Connection: This section leads to understanding the importance of oceans and continents for life on Earth.
Frequently asked questions
1. What are oceans and continents? What are their names and their distribution?
Oceans are the largest water bodies on Earth, covering almost three-fourths of the Earth's surface. Continents are large continuous expanses of land, covering a little over one-fourth of the Earth's surface. The five oceans are the Pacific Ocean, Atlantic Ocean, Indian Ocean, Arctic Ocean, and Southern Ocean. Continents and oceans are unevenly distributed between the Northern and Southern Hemispheres, with the Northern Hemisphere having more land and the Southern Hemisphere more water.
2. In what ways do oceans and continents impact life on Earth, including human life?
Oceans and continents shape the Earth's climate, influencing weather patterns and temperatures. They affect all forms of life including plants, animals, and humans. Oceans provide habitats for marine life and influence rainfall and temperature. Continents provide land for human habitation, agriculture, and biodiversity. Their distribution affects cultural history and daily human activities.
→ What are the circular lines in each map called? And do you know what the lines radiating out of the two poles are called? (Hint: you studied them in the previous chapter, but here they are presented differently.) → Which hemisphere holds more water? → What do you think could be the approximate proportion of water to land in the Northern Hemisphere? And in the Southern Hemisphere? Discuss in groups. → Are all the oceans connected with one another, or are there separations between them?
1. The circular lines in each map are called parallels or lines of latitude. The lines radiating out of the poles are called meridians or lines of longitude. 2. The Southern Hemisphere holds more water compared to the Northern Hemisphere. 3. Approximate proportion: Northern Hemisphere has more land than water (about 60% land, 40% water), while the Southern Hemisphere has more water than land (about 80% water, 20% land). 4. All oceans are connected; the divisions on maps are conventional boundari
## LET'S EXPLORE Locate the five oceans and, in the table below, mark the hemisphere or hemispheres they belong to. | | Northern Hemisphere | Southern Hemisphere | | --- | --- | --- | | Pacific Ocean | | | | Atlantic Ocean | | | | Indian Ocean | | | | Southern Ocean | | | | Arctic Ocean | | |
Pacific Ocean: Both Northern and Southern Hemispheres Atlantic Ocean: Both Northern and Southern Hemispheres Indian Ocean: Both Northern and Southern Hemispheres Southern Ocean: Southern Hemisphere only Arctic Ocean: Northern Hemisphere only
