The slogan of rock tea

A. According to the concept analysis of Danxia landform, the first geological process of this landform formation is that the crust descends to form the ocean. Sandstone sedimentary rocks are formed by external forces. After sedimentary rocks are formed, they are exposed to the surface to form mountains. After they were exposed to the surface, they formed the present landscape under the erosion of external forces and flowing water. Therefore, the formation process of this landscape is crustal decline-deposition-crustal uplift-flowing water erosion. Therefore, the order of corresponding maps is d, a, b and C.

B, according to the concept analysis of Danxia landform, the final process of this landform formation is that the landform formed by flowing water erosion is C diagram, so it does not meet the meaning of the question;

C, according to the concept analysis of Danxia landform, the final process of this landform formation is that the landform formed by flowing water erosion is C diagram, so it does not meet the meaning of the question;

D. According to the concept analysis of Danxia landform, the first geological process of this landform formation is that the crust descends to form the ocean. Sandstone sedimentary rocks are formed by external forces. After sedimentary rocks are formed, they are exposed to the surface to form mountains. After they were exposed to the surface, they formed the present landscape under the erosion of external forces and flowing water. Therefore, the formation process of this landscape is crustal decline-deposition-crustal uplift-flowing water erosion. Therefore, the order of corresponding maps is d, a, b and C.

Therefore, choose: d.
