Anonymous users2024-02-12Most of the energy on the earth comes from the solar energy generated by the sun, and improving the utilization rate of energy is conducive to protecting our earth, which is like not wasting in life.

Anonymous users2024-02-11The energy on earth is wind, solar, and geothermal. Geothermal energy comes from the interior of the earth, wind energy is formed by the horizontal movement of air currents, and solar energy comes from the sun. There is a time when oil and other resources are depleted, so we need to improve energy efficiency and increase the use of recyclable resources.

Analysis: Plants use the sun's energy to grow through photosynthesis and convert light energy into chemical energy, herbivores obtain energy by eating plants, and carnivores obtain comic energy by killing herbivores, so in the final analysis, the energy consumed by plants and animals on the earth comes directly or indirectly from the sun's energy.

Anonymous users2024-02-08The vast majority of the energy on Earth is generated by solar radiation. Only a few** on Earth and the Moon. The sun is a huge energy source, it radiates a huge amount of energy in all directions at all times, it is all kinds of plants that convert solar energy into chemical energy through photosynthesis and store it in the plant, the organisms that capture the sun are mainly green plants, and green plants can convert solar energy into chemical energy through photosynthesis.
Introduction to Earth Energy:According to Einstein's mass-energy equation, processes such as the collapse of matter will lose mass and release energy, and some processes will release gravitational potential energy (potential energy is equivalent to stored energy). The earth's energy includes solar energy and energy provided by the earth itself, such as heat energy produced by the decay of radioactive elements.
Most people accept that the universe is from the beginning, and then the universe begins to produce various elements and substances, and this process can release huge energy.

Earth (one of the eight planets of the solar system) is locked.
Earth is one of the eight planets in the solar system, the third planet in order from near to far, and it is also the terrestrial planet with the largest diameter, mass and density in the solar system, 100 million kilometers away from the sun. The Earth rotates from west to east while revolving around the Sun. It is 4,04.6 billion years old,[1] and it has a natural satellite, the Moon, which forms a celestial system, the Earth-Moon System.
It originated from the primordial solar nebula 4.6 billion years ago.
The radius of the Earth's equator is kilometers, the polar radius is kilometers, the average radius is about 6,371 kilometers, and the circumference of the equator is about 40,076 kilometers. The surface area of the earth is 100 million square kilometers, of which 71% is oceans and 29% is land.
The interior of the earth has a core, mantle, and crust structure, and the outside of the earth has a hydrosphere, atmosphere, and magnetic field. The Earth is the only celestial body in the universe where life is known to exist, and it is home to millions of living beings, including humans. [1]

Anonymous users2024-02-06Most of the plants on Earth need sunlight for photosynthesis, and solar energy is converted into chemical energy during the photoreaction phase. Animals eat plants, and people eat animals and plants, so the ultimate energy source for people comes from solar energy. x0d The evaporation of seawater on the earth, the water cycle must also be sunshine.
The x0d temperature difference forms the air pressure difference, and the air pressure difference forms the wind, and the formation of the wind must also be ...... by sunlightX0dOverall, the vast majority of Earth's energy comes from solar energy. x0d As for other energies, there are geothermal energy, nuclear energy, electrical energy, tidal energy, etc., the motion of the object has kinetic energy, the gravitational potential energy possessed by the object at a height due to the attraction of the earth, etc.
For the energy of the earth, it is nothing more than mass and heat. It is said that the earth receives about 10 tons of cosmic dust every day, which is several orders of magnitude larger than those satellites and probes that have only been available in recent decades. >>>More
All energy on Earth comes from the sun, including energy from the Earth's interior. And now the scholars are wrong about radioactive energy. The only energy on the earth** is solar energy, and a part of the solar energy is converted into the earth's internal energy.
The solar system is a nebula, in the cosmic region very close to the solar system at that time, there was a large star death event, the mass of this star is at least 8 times more than the sun, before the death, this late star, that is, the supernova had a violent instantaneous **, this instantaneous big ** made the density of the nebula where the solar system is located changed, the collapse of this region began, followed by the change of gravity, a large number of movements and collisions began, and the final result was the formation of a huge sun, It has a very high internal temperature, with a core temperature of up to 15 million degrees. The rest of the various materials were thrown into space, and because of the huge mass of the sun, they began to move around the sun and slowly began to coalesce together to form planets. >>>More
