介绍:
1. Wind erosion is a natural process that detaches soil particles from one area of the land’s surface and transports it to another location where it is deposited. 2. Wind erosion can move only small particles, so it is most prevalent in dry areas. In dry soils, there is less water to hold surface particles together. Deserts and drought areas are particularly affected by wind erosion. 3. Such wind erosion has resulted in a variety of landforms. As soil particles move, they abrade surfaces. The strange-shaped sculptures we see in deserts are created by abrasion. 4. Although it is a natural process, wind erosion threatens agriculture around the world, particularly in dry regions. Dust storms diminish air quality and negatively impact health and the economy. 风蚀是一种自然的过程,它会剥离一处地表的土壤颗粒并将其带到另一处留存下来。 风蚀只能移动微小颗粒,所以风蚀盛行于干旱地区。在干燥的土壤中,水分缺少导致地表土壤颗粒无法聚集在一起。沙漠和干旱地区尤其会受到风蚀的影响。 风蚀造就了多种多样的地形。当土壤颗粒移动,它们会磨损表面。我们在沙漠中看到的造型奇异的雕塑就是由于磨损形成的。 尽管风蚀是一种自然的过程,但是它危害全球农业,尤其是干旱地区。沙尘暴会降低空气质量,对健康和经济产生不良影响。
