D. disappears
解析：if的虚拟语气非常重要，简要概括如下：1、表示与现 在事实相反的情况，从句：If主语+过去时(Be动词用were)；主句：主语+should/would/could/might+do： 2、表示与过去事实相反的情况，从句：If主语+had+done；主句：主语+should/would/could/might+have done 3、表示对将来情况的主观推测，从句：①if+主语+were to do②if+主语+should+do ③if+主语+did（动词过去式）/were ；主句：主语+should/would/could/might+do；根据第一句中的stopped，可知本句应该是与现在事实相反的虚拟语气，使用主句中使用would+动词原形。句义：如果地球停止转动，一切都会消失。故A正确。
