What are renewable resources among natural resources: Solar energy, water resources, forest resources and wind energy are renewable resources.
1. Natural Resources
Natural resources refer to substances found in nature that humans can obtain directly for production and life. Natural resources can be divided into renewable resources, renewable natural resources and non-renewable resources. Natural resources are characterized by their availability, integrity, variability, uneven spatial distribution and regionality. Natural resources can be divided into: biological resources, agricultural resources, forest resources, land resources, mineral resources, marine resources, climate and meteorology, water resources, etc.
2. Resources rrevolvable
1. Resources that are regenerated and updated through natural processes and therefore repeatedly used by humans are called renewable resources, also known as renewable resources. renewable resources. Update resources such as plants, microorganisms, degradable plastic bags, water resources, geothermal resources and various natural biomes, forests, grasslands, aquatic life, etc.
2. Renewable natural resources can continue to regenerate and renew themselves, multiply and grow, maintain or expand their reserves, and rely on sources to regenerate within the specific temporal and spatial conditions of nature at that time. stadium. generally refer to those obtained from nature. Non-fossil renewable energies mainly refer to natural energies such ass such as wind energy, solar energy, hydroelectric energy, geothermal energy and ocean energy.
3. Definition of renewable resources
1. Directly from solar radiation, mainly providing heat and electricity.
2. Bioenergy. Green plants convert solar energy into chemical energy through photosynthesis, which is stored in the body. It can flow in one direction along the food chain, and is finally converted into thermal energy and biogas is obtained by combustion and anaerobic fermentation to obtain energy. .
3. Wind energy. Energy is provided by solar radiation. The difference in air pressure caused by unequal cold and heat causes horizontal movement of air. Wind formation mainly obtains energy from wind turbines.
4. Water energy. The energy is supplied byr solar radiation, creating a water cycle. Warm, moist ocean air rises when heated, and solar energy is converted into potential energy. When precipitation forms on mountains, water flows to lower places. potential energy is converted into kinetic energy, which is the energy of water, mainly through hydroelectric generator to obtain energy.
5. Ocean energy. The energy contained in the movement of sea water, including tides, waves, ocean currents, etc., is also inexhaustible. Tidal energy comes primarily from the gravity of celestial bodies like the moon and sun. mainly affected by the wind, it produces electricity thanks to the kinetic energy of the tides.
6. Geothermal energy. It comes from the decay of radioactive elements inside the Earth and can be used for geothermal energy productionmic and heating.
7. Hydrogen energy. Energy is obtained by combustion or fuel cells.
8. Nuclear energy. Energy is obtained through nuclear power plants.
