Percentage of Earth covered by water and land

The correct answer is option 'C', which states that 71% of the Earth is covered by water, while 29% is covered by land. Let's explore this in more detail:

1. Earth's surface
- The Earth is a planet in our solar system, and its surface is made up of land and water bodies.
- The Earth's surface is divided into continents and oceans, which together make up the total area of the planet.

2. Oceans
- Oceans are vast bodies of saltwater that cover most of the Earth's surface.
- There are five main oceans on Earth: the Pacific Ocean, the Atlantic Ocean, the Indian Ocean, the Southern Ocean, and the Arctic Ocean.
- These oceans are interconnected and cover around 71% of the Earth's surface.
- The Pacific Ocean is the largest and deepest ocean, followed by the Atlantic Ocean.

3. Continents
- Continents are large landmasses that are above water on the Earth's surface.
- There are seven continents on Earth: Africa, Antarctica, Asia, Europe, North America, Australia, and South America.
- These continents make up the remaining 29% of the Earth's surface.

4. Calculation of percentages
- To determine the percentage of Earth covered by water and land, we consider the total surface area of the planet.
- Since water covers about 71% of the Earth's surface, it accounts for the larger portion.
- Therefore, the percentage of Earth covered by water is 71%.
- Similarly, land covers the remaining 29% of the Earth's surface, so the percentage of Earth covered by land is 29%.

Summary
In conclusion, 71% of the Earth's surface is covered by water, while 29% is covered by land. This distribution of water and land creates a diverse planet with various ecosystems and habitats.
