Poetry and landforms: my country has a vast territory and diverse landform types, each with different causes. There are external forces such as weathering, erosion, transportation, and sedimentation, and internal forces such as crustal movement. For example, "The green mountains on both sides of the strait are facing each other, and the solitary sail is coming from the sun" (Li Bai of the Tang Dynasty) can be understood as a description of the landform eroded by flowing water. That is, when the earth's crust is uplifted, the flowing water cuts deep into the valley, causing "the green mountains to face each other." And Among the descriptions of karst landforms, Lu Lun, a famous poet of the Tang Dynasty, wrote "Green clouds emerge from the road, and the wild countryside enters the deep caves". It is an excellent poem that describes the landforms of the Guizhou Plateau where the karst landforms are in the middle stage of development. The description is clear and appropriate. Naturally, it shows the landform characteristics of the Guizhou Plateau. "The road to Shu is difficult, and it is difficult to reach the blue sky." landforms. "Viewed horizontally, there are ridges and peaks, with different heights near and far." (Su Dongpo, Song Dynasty)'s poem is a typical description of mountain topography, reflecting the majesty and beauty of Mount Lu. "Egret Island is divided into the middle" (Li Bai) "On the beach, thin grass meets sparse forest, and the waves are so bad that the boat is about to sink." The common herons and gulls are not in Jiupu, but last year the sand spit was in the center of the river" ("Huangfu Song" in Tang Dynasty) can illustrate the sedimentary landform of the Hexin Island formed by river alluvial. "The sky is blue, the fields are vast, and the grass is blown by the wind and cattle and sheep are low" ("Hulüjin" in the Northern Dynasties) shows the vast and magnificent grassland landforms of China's Inner Mongolia Plateau, vividly depicting the fertile grassland, the herds of cattle and sheep, and the peace and tranquility. "The water of the Yellow River comes up from the sky and flows eastward to the sea and never returns" (Li Bai) not only explains that the terrain of our country is higher in the west and lower in the east, but also reveals the law of water circulation between sea and land. The land runs off into the sea, and seawater can only flow from there. The air is transported to the land through the atmosphere. The implicit water cycle regenerates and replenishes the water resources on the land.

Poetry and water energy: There are three basic conditions for the formation of water energy resources: river canyon, drop and water volume. There are also many poems describing this aspect. For example, Li Bai's "Flying down three thousand feet, it seems that the Milky Way falls from the sky" is a description of Lushan Waterfall, and we can understand that the waterfall contains huge water energy resources for us. Go to development and utilization. The apes on both sides of the bank can't stop crying, and the light boat has passed the Ten Thousand Mountains." (Li Bai) It not only shows the majestic and majestic scene of the surging Yangtze River flowing through the Three Gorges, but also reflects the large gap in the Three Gorges and the concentration and abundance of water energy resources. "The tides are born with the moon, and the rivers are born with the spring" (Liu Yuxi) "The eighteen tides in August are as spectacular as the world has ever seen" (Su Dongpo) "The desperate shore is worried about overturning, but the light boat is returning to the sea" (Shi Runzhang of the Qing Dynasty) and so on show the surging tide of Qiantang. The majestic momentum of the tide, the most spectacular time of the tide and the astronomical factors that form the tide also imply that the tidal energy is huge, and if it is developed and utilized, it will definitely benefit mankind.

Poems and the Earth’s Rotation: The Earth’s rotation is one of the most basic forms of Earth’s motion. The apparent motion caused by rotation is naturally that earth objects move eastward and celestial objects move westward. "The setting sun is infinitely beautiful, but it is almost dusk" (Li Shangyin of the Tang Dynasty), "The sun sets over the mountains, and the Yellow River flows into the sea" (Wang Zhihuan), "It has just been swept away by the sun, but it teaches the bright moon to see the future" (Xie Fangde of the Southern Song Dynasty) etc., can be properly used to explain the apparent motion of the earth's rotation and the myriad scenes of the approaching twilight line.
