Options

A. 0.006
B. 0.06
C. 0.6
D. 6

Answer

To determine the percentage of water available for human use on Earth, we can break down the information as follows:

### Step 1: Understand the distribution of water on Earth
- The majority of Earth's water is found in seas and oceans, which accounts for about **97.4%** of the total water.
- A significant portion, around **2%**, is frozen in glaciers and polar ice caps.

### Step 2: Identify the fresh water available for use
- The remaining water, which is not in seas, oceans, or frozen, is fresh water. This accounts for about **0.6%** of the total water on Earth.
- This fresh water is further divided:
- **0.59%** is available as groundwater.
- **0.01%** is available as surface water (like rivers and lakes).

### Step 3: Conclude the percentage available for human use
- Since we are looking for the percentage of water that is available for human use, we focus on the **0.6%** of fresh water that is accessible in liquid form.

### Final Answer
The percentage of water present on Earth that is available for us is roughly **0.6%**.
