饱含碳酸氢钙的地下水溢出地表，沿斜坡漫流时，遇到地表凸起部位，水流翻越阻隔流速加快，水体变薄，水中的二氧化碳逸出，在凸起部位发生碳酸钙淀积，形成“边石坝”。下图是某处边石坝景观及其纵向剖面图，剖面呈现黄白相间的纹理。进一步研究发现白色是碳酸钙，黄色是泥土。读图回答以下问题。
关于边石坝生长速度最快部位的判断及原因分析正确的是（ ）
| A．A因为A处是边石坝最高凸起点，水体最薄，碳酸钙沉积最快 |
| B．B因为B处流速最快，碳酸钙沉积最快 |
| C．C因为C处受凸起阻挡，流速最慢，流水搬运的碳酸钙物质最易沉积 |
| D．D因为D处位于钙化池内，流速最慢，流水搬运的碳酸钙最易沉积 |
根据边石坝黄白相间纹理，下列推理判断正确的是（ ）
①该边石坝可能形成于季风气候区
②该边石坝可能形成于温带海洋性气候区
③雨季时，河流流量大，搬运力强，泥沙不易沉积，纹理呈白色
④雨季时，河流流量大，侵蚀力强，含沙量大，钙化沉积物中混有泥沙，纹理呈黄色
⑤黄宽白窄，说明暴雨次数多，雨季长
⑥白宽黄窄，说明暴雨次数多，雨季长
| A．①③⑥ | B．①④⑤ |
| C．②④⑤ | D．②③⑥ |
