B．the lack of protection from the sun
C．the tropical location of deserts
D．the absence of rain此题为多项选择题。请帮忙给出正确答案和分析，谢谢！
参考答案
正确答案：B
解析：根据第二段第三旬“There are virtually no clouds or trees to protect the earth’s surfface andit can be burning hot．Under the sun，soils break up and crack…”可知，在沙漠地区没有云、没有树保护地面，地面很容易曝晒，因此裂开。B项说地面缺乏保护，符合句意。
