Solving geographical knowledge question and answer with poetry

The first sentence. This is the vertical difference of climate. The temperature decreases with the elevation. Every altitude 100 meters, the temperature drops by 0.6 degrees Celsius. Naturally, the temperature on the mountain is lower than that under the mountain, and the flowering period is later. Mountain vertical climate and poetry: Bai Juyi's \ "April, the world is full of flowers, and the mountain temple is full of peach blossoms. This vividly reflects the vertical difference of phenology in mountainous areas. Normally, the temperature drops by 0.6℃ for every elevation increase of 100 m. Altitude of Dalin Temple in Lushan Mountain 1.

100~ 1

Between 200 meters, the temperature is about 6℃ lower than the average elevation of 32 meters in Jiujiang City. Therefore, the flowering time of peach blossoms is 20 ~ 30 days later, so the phenology on the mountain is delayed by about one month.

The second sentence. It is the reason why China is high in the west and low in the east that makes the water flow from west to east. "Into the ocean, never to return" is correct on the surface, but the process of water circulation is not like this. There is a land-sea cycle, or a big cycle. After the land water reaches the ocean, the water in the ocean evaporates and is replenished to the river through the precipitation on the land. Without this process, the river would have dried up long ago.
