Explain the geographical phenomenon or landscape in tourism with geographical knowledge.

1. In the northern hemisphere, trains drive on the left (double track) to avoid the risk of collision due to the deflection force of the earth's rotation;

2. In summer, the temperature in cities or towns is higher than that in suburbs or rural areas because solar radiation absorbs heat quickly and dissipates heat slowly; It is warmer in winter; Under the same latitude position, the coastal area is slightly cooler in summer and warmer in winter than the inland area (the thermal effects of land and sea are different, and the heat dissipation at sea is slower); The temperature difference between mountains and plateaus is large (more sugar is accumulated in fruits and vegetables), while the temperature difference between plains is small (less sugar is accumulated in fruits and vegetables);

3. Sunset and sunrise are later in the west than in the east; The sunshine time in plateau is longer than that in plain or hilly areas, such as Qinghai-Tibet Plateau and Yunnan-Guizhou Plateau.
