My mother only has one eye. I hate her. I am always angry about it. She cooks dinner for students and teachers. One day at school, my mother sees me and says hello to me. I was so unhappy! How can she do this? I turn back and run away. The next day at school one of my classmates says,“EEEE, your mother only has one eye!” I don't know what to say. I wish my mother to just get away. I say to her at home, “If you’re only going to make others laugh at(嘲笑)me, why don’t you just die ?” She doesn't say a word. Many years later, I have my family in another city. Then one day, my mother根据材料和图，结合所学知识，回答下列问题。地理环境是一个整体，一个区域地表形态的变化往往受另一个区域物质运动的影响。  （1）描述图示期间该区域陆地变化特点，并指出其泥沙的主要来源区。___________________________________________________________________________________________（2）泥沙主要来源区的哪些气象灾害会加速该区域陆地面积的变化？为什么？___________________________________________________________________________________________
