Five important water features are

Answer 1

Water has lots of features, I am not sure who told you there are only five. Here are some features of water:

It is a liquid at room temperature.

It is transparent.

It is necessary for life.

It is a compound of hydrogen and oxygen.

It evaporates.

It is abundant here on the planet Earth, and forms rivers, lakes, oceans, etc.

It is a very powerful solvent.

It is a polar compound, whose molecule has a negative pole and a positive pole.

It is a product of any kind of combustion of compounds which include hydrogen, such as hydrocarbons (including gasoline).

Water also has the very interesting feature that it expands in volume slightly when it freezes, so that ice is less dense than water and floats on water. This is very unusual, since almost all known chemical substances are more dense in their solid form than they are in their liquid form.

Answer 2

1. Rivers: They provide freshwater for drinking, irrigation, and transport, serving as vital habitats for aquatic species.
2. Lakes: These large bodies of water play significant roles in regulating local climates, supporting biodiversity, and offering recreational opportunities.
3. Oceans: Covering the majority of the Earth's surface, oceans influence global weather patterns and support a wide array of marine ecosystems.
4. Waterfalls: These natural formations are not only visually stunning but also important for nutrient circulation and serve as barriers to prevent fish migration.
5. Wetlands: Functioning as crucial ecosystems, wetlands provide flood control, water purification, and habitat for diverse plant and animal species.
