Coal mines are necessary for electricity generation in the Lingnan region. Power generation in Lingnan area relies on coal, hydropower, solar power, nuclear power, wind power, fuel oil, etc., power generation in Lingnan area therefore requires coal mines. Lingnan is the general name for the region south of the Five Peaks in southern China, separated from the inland by the Five Peaks. The Wuling Mountains are composed of five mountains: Yuecheng Ridge, Dupang Ridge, Mengzhu Ridge, Qitian Ridge and Dayu Ridge. They are generally distributed from eastern Guangxi to eastern Guangdong and the borders of the four provinces of Hunan and Jiangxi.
(1) The specific heat capacity of water is large. During the day, under the same conditions of heat absorption, the water temperature increases less. At night, when the same heatr is released, the temperature. water decreases less. The temperature difference between day and night is smaller;
The specific heat capacity of sand and gravel is low. Under the same heat absorption conditions, the temperature of sand and gravel increases a lot. at night, when the same heat is released, the temperature of the sand and gravel drops a lot, day and night.
(2) The sea and land wind formed can produce electricity thanks to the wind turbines. The process of generating electricity involves converting wind energy into electrical energy.
So the answer is: specific heat capacity; electricity.
