How much of the Earth’s surface is covered with water?*1 pointAbout 71%About 50%About 3%About 15%

The Earth's surface is covered by a significant amount of water, primarily in the form of oceans, seas, rivers, and lakes. To clarify this question, we can analyze the options provided:

1. About 71%: This is the commonly accepted scientific estimate of the percentage of the Earth's surface that is covered by water. This figure takes into account all bodies of water, including the vast oceans, which hold about 97% of the Earth's water supply, and smaller bodies like lakes and rivers.

2. About 50%: This option underestimates the amount of water present on Earth’s surface. The actual figure is considerably higher.

3. About 3%: This number refers to the percentage of water that is freshwater, which is only a small fraction of the total water on Earth. While essential for human life and ecosystems, it does not represent the total coverage of the Earth's surface.

4. About 15%: This is also incorrect and significantly lower than the actual figure.

Final Answer

The correct answer is About 71%, as this reflects the approximate portion of the Earth's surface that is covered by water.
