Renewable resources are called flow resources because they are replenished naturally and continuously through natural processes. These resources have a constant flow and can be used without the fear of depletion.

Examples of renewable resources that are flow resources are:

1. Solar Energy: Solar energy is a flow resource because it is generated by the sun's radiation, which is a constant flow of energy. The sun's energy is harnessed by solar panels, and it can be used to power homes, buildings, and even entire cities.

2. Wind Energy: Wind energy is also a flow resource because it is generated by the wind, which is a natural flow of air. Wind turbines are used to harness the wind's energy, and it can be used to power homes and businesses.

3. Hydroelectric Energy: Hydroelectric energy is a flow resource because it is generated by the flow of water in a river or stream. A dam is built across the river or stream, and the water flow is used to turn turbines, which generates electricity.

4. Geothermal Energy: Geothermal energy is a flow resource because it is generated by the flow of heat from the earth's core. Geothermal power plants are built near geothermal hotspots, and the heat is used to generate electricity.

5. Biomass Energy: Biomass energy is a flow resource because it is generated by the growth of plants and trees. The plants and trees are harvested and used to produce energy through processes like burning or fermentation.

In conclusion, renewable resources are called flow resources because they have a constant flow that is replenished naturally and continuously through natural processes. These resources are essential for sustainable development and can be used without the fear of depletion.

Flow resources are resources which can be continuously used on the other hand renewable resources are those who cannot be replinshed or can be exhausted .
in my opinion these are called renewable but for some conditions for e.g - gravity light ,solar energy
