Land Area Percentage on Earth
The correct answer is option 'B', which states that approximately 30% of the Earth's area is occupied by land. Let's explore the reasons behind this answer in detail.
1. Earth's Total Area:
- The Earth has a total surface area of around 510 million square kilometers.
- This includes both land and water bodies.
2. Water Bodies:
- The Earth's surface is predominantly covered by water bodies, including oceans, seas, lakes, rivers, and other smaller water sources.
- These water bodies account for approximately 70% of the Earth's total area.
3. Land Area:
- Land areas are the portions of the Earth's surface that are not covered by water bodies.
- These areas include continents, islands, and other landforms.
- Land areas account for the remaining percentage of the Earth's surface, which is approximately 30%.
Therefore, the correct answer is option 'B' – 30% of the Earth's area is occupied by land.
Summary:
- The Earth's total area is around 510 million square kilometers.
- Water bodies cover approximately 70% of the Earth's surface.
- Land areas account for the remaining 30% of the Earth's surface.
