地理高考答题技巧（Geography entrance examination skills） First, the factors affecting the duration of sunshine: 1, the length of the day; 2, the terrain (high terrain, sunrise early, sunset late, long sunshine); weather conditions. Two, the factors affecting the intensity of solar radiation (that is, the impact of atmospheric radiation on the sun weakened factors), 1, the sun height (latitude); 2, weather conditions; 3, topography; 4, air density. For example, why is the Qinghai Tibet Plateau the strongest solar radiation? (1) the latitude is lower and the sun is larger; the weather is much higher; the terrain is high; the air is thin and the atmosphere is clean. Three, factors affecting the temperature: 1, latitude; 2; topography and topography; 3, the nature of the underlying surface (land and sea position, vegetation status); 4, weather conditions. Four, the influence factors and variation of temperature: 1, latitude: low latitude, high latitude; 2, the surface ocean is less than coastal land, less than inland, vegetation is less than bare land; 3, weather conditions in many places is less than the cloud: cloud little place. Five, river governance measures: Upstream: governance principle is the flood, it is the reservoir, afforestation; midstream: flood diversion and flood control principle is that practice is to build the reservoir, flood diversion and flood project; management principle is: downstream flood discharge, water is beam, reinforced embankment, river dredging, excavation of river. Six. Analysis of the causes of river floods: Natural causes (mainly from three aspects: water hydrology, climate); human factors (mainly from two aspects: the destruction of vegetation, weihuzaotian). For example, the cause of floods in the Yangtze river: Natural causes: 1. Characteristics of river system: (1) the basin is wide and the tributaries are numerous; secondly, the vegetation in the middle and upper reaches is seriously damaged; the sediment content increases; the middle a
