Question

Earth is called the blue planet because 71% of the Earth's surface is covered with water, but we still face and hear stories about water shortage. What can be the possible reason for this?

• A. Ocean water cannot be used on land
• B. Most of the available water is salty and unfit for consumption
• C. Ocean water is full of disease-causing microbes
• D. Ocean water is available only in coastal areas

Answer 1

The correct option is B

Most of the available water is salty and unfit for consumption

Though the Earth's surface has around 71% percent water, we still face water shortage because most of the water available is in oceans. This water is salty and cannot be used for our daily activities directly. The process of converting this salt water to freshwater is very expensive.
