it是形式主语.作为形式主语的it并无实际语义，只是为满足语法上的需要，避免句子头重脚轻，它代替的是句子的逻辑主语.这句话真正的主语是"the earth is round"

最标准的答案是： it 是形式主语，真正的主语是that引导的从句，英语中为了避免头重脚轻（即主语过长）常常用it做形式主语，that引导主语从句。
That the earth is round is known to all.
强调句型
除去it is..that 后的句子
the earth is round known to all 仍然是一个完整的句子
宾语丛句
it 作形式主语
宾语丛句
it 作形式主语,指the earth is round
