丹霞地貌是由红色砂砾岩经外力作用形成的一种景观。左图为中国丹霞地貌集中分布区示意图，右图为岩石圈物质循环示意图。读图回答下列各题。
右图中（）
A.①作用使甲岩石多分布在火山口附近
B.②作用仅发生在莫霍界面以上
C.③作用形成丹霞地貌
D.④作用能量来自地球内部
参考答案：D
解析：根据上题的分析，甲为沉积岩，乙为岩浆岩，丙为岩浆。①作用为外力作用，甲岩石为沉积岩，其分布与火山口无关，A错；②作用为重熔再生作用，不仅发生在莫霍界面以上，B错；③作用为冷却凝固，而丹霞地貌的成因为外力作用，C错；④作用为变质作用，其能量来自地球内部，D对。答案选D。考点：该题考查丹霞地貌分布区的特点和地壳的物质循环。
Do you often think of your parents? You may say, “Of course, I 1 . I buy a present for my mother on Mother’s Day and on Father’s Day I give my father 2 ,too.” But what about the other days of the year? I have a friend whose parents live in another city.
