What is Distribution of Oceans and Continents Class 11: Complete Guide
By ConceptScroll Team · Published on 18 June 2026 · 4 min read
What is Distribution of Oceans and Continents Class 11? It refers to how Earth's surface is divided between large landmasses (continents) and vast water bodies (oceans). This chapter in NCERT Geography explains the position, size, and features of oceans and continents, essential for Class 11 students to grasp Earth's physical geography.
Overview of Earth's Oceans and Continents
Earth's surface comprises two main features: continents and oceans. Continents are large landmasses, while oceans are vast water bodies covering most of the planet. Together, they shape the planet's geography and influence climate and ecosystems.
- Continents cover about 29% of Earth's surface.
- Oceans cover approximately 71%.
The seven continents are Asia, Africa, North America, South America, Antarctica, Europe, and Australia. The five oceans include the Pacific, Atlantic, Indian, Southern, and Arctic Oceans.
Understanding their distribution helps students in Class 11 grasp Earth's physical structure and prepare for NCERT exams.
Major Continents: Size, Location, and Features
The seven continents differ in size, location, and physical features:
| Continent | Approx. Area (million sq km) | Location | Key Features |
|---|---|---|---|
| Asia | 44.58 | Northern and Eastern Hemispheres | Largest continent, diverse climates |
| Africa | 30.37 | Equator to Southern Hemisphere | Rich in minerals, deserts, rainforests |
| North America | 24.71 | Northern Hemisphere | Varied landscapes, Great Lakes region |
| South America | 17.84 | Southern Hemisphere | Amazon rainforest, Andes mountains |
| Antarctica | 14.0 | Southern Hemisphere | Ice-covered, coldest continent |
| Europe | 10.18 | Northern Hemisphere | Densely populated, historical sites |
| Australia | 7.69 | Southern Hemisphere | Island continent, deserts, reefs |
Each continent has unique physical and cultural characteristics important for Class 11 Geography.

Distribution of Oceans: Characteristics and Importance
The five oceans cover most of Earth's surface and play vital roles in regulating climate, supporting marine life, and enabling transportation:
- Pacific Ocean: Largest and deepest ocean, located between Asia, Australia, and the Americas.
- Atlantic Ocean: Second largest, separates the Americas from Europe and Africa.
- Indian Ocean: Third largest, bounded by Africa, Asia, and Australia.
- Southern Ocean: Encircles Antarctica, important for cold water currents.
- Arctic Ocean: Smallest and shallowest, located around the North Pole.
Oceans influence weather patterns, provide resources like fish and minerals, and are crucial for global trade routes.
How Continents and Oceans are Distributed Globally
The distribution of continents and oceans is uneven but follows a pattern shaped by tectonic forces:
- The Pacific Ocean occupies the largest area, surrounded by the 'Ring of Fire' with many volcanoes and earthquakes.
- The Atlantic Ocean is narrower but important for connecting Europe, Africa, and the Americas.
- Continents like Asia and Africa are mostly in the Eastern Hemisphere, while North and South America lie mainly in the Western Hemisphere.
This distribution affects climate zones, ocean currents, and biodiversity hotspots worldwide.
Comparison of Continents and Oceans by Area and Location
Below is a comparison table summarizing the size and hemispherical location of continents and oceans:
| Feature | Area (million sq km) | Hemisphere(s) |
|---|---|---|
| Asia | 44.58 | Northern, Eastern |
| Africa | 30.37 | Equator, Southern |
| North America | 24.71 | Northern, Western |
| South America | 17.84 | Southern, Western |
| Antarctica | 14.0 | Southern |
| Europe | 10.18 | Northern, Eastern |
| Australia | 7.69 | Southern, Eastern |
| Pacific Ocean | 168.72 | Both Hemispheres |
| Atlantic Ocean | 85.13 | Both Hemispheres |
| Indian Ocean | 70.56 | Southern, Eastern |
| Southern Ocean | 21.96 | Southern |
| Arctic Ocean | 15.56 | Northern |
This comparison helps students visualize how Earth's surface is divided.
Worked Example: Calculating Percentage of Earth's Surface Covered by Oceans
Given that oceans cover about 361 million sq km and Earth's total surface area is approximately 510 million sq km, calculate the percentage of Earth's surface covered by oceans.
Solution:
$$\text{Percentage} = \left( \frac{\text{Area of Oceans}}{\text{Total Surface Area}} \right) \times 100$$
$$= \left( \frac{361}{510} \right) \times 100 \approx 70.78\%$$
Therefore, oceans cover approximately 71% of Earth's surface, confirming the data studied in Class 11 NCERT Geography.
