The temperature of the earth

The temperature on the earth's surface is influenced by solar radiation, and the global average surface temperature is about 15℃.

In the deep underground where there is no sunlight, the temperature is mainly influenced by geothermal energy, and increases with the increase of depth. The core temperature at the center of the earth is higher than 6℃, which is higher than the surface temperature of the solar photosphere. The hottest place on the earth's surface appears in Basra, with the highest temperature of 58.8℃.

The "cold pole" in the northern hemisphere of the earth is located in Oymyakon in the mountains of eastern Siberia. The lowest temperature in January 1961 was-71℃. The world's "cold pole" is in the Antarctic continent. In early 1967, Russians recorded the lowest temperature of-89 and 2℃ at Dongfang Station.

the source of temperature on the earth

the temperature inside the earth is formed under the irradiation of the sun, and all substances will store heat. Because the earth has a certain saving power, the temperature on the surface of the earth has gradually increased. At noon, the sun shines the strongest, and the more temperature the earth saves; At night, the sun is farther and farther away from the surface of the earth, and the heat inside the earth is less and less.

The temperature on the earth began to be saved in spring. In summer, the temperature on the surface of the earth is getting higher and higher. In autumn, the weather is still hot, because the heat saved in summer has not been exhausted.

The sun in the sky is very far away from us, and there is a vacuum layer between the sun and the earth. The sun transfers certain heat energy to the earth by ignition.

There is a certain temperature on the surface of the earth, which can decompose water molecules in the air into hydrogen and oxygen, and hydrogen begins to heat and glow under the ignition of sunlight. Oxygen in the air will help combustion, and hydrogen in the air will start to burn continuously with the help of oxygen. The stronger the sun shines, the faster the water molecules in the air decompose. The faster the water molecules decompose, the more they burn, and the higher the temperature on the earth's surface.
