River migration This photo from above catches several stages in river evolution. In a meandering river system like this one, river meanders grow outward by eroding away at a cutbank. Sediment moved away from the cutbank often is deposited on a point bar on the inside of a growing meander – the sand bars stand out clearly in this photo, showing meanders in various states of growth. River meanders grow outward through this process until eventually the meander gets so big that the river breaks through and establishes a new, shorter course. When that breakthrough happens, it often strands the old meander as an abandoned channel known as an oxbow lake. -JBB Image credit: https://www.flickr.com/photos/maitri/73035629/

Uma cratera invertida em Marte. Uma cratera comum de impacto foi preenchida por material sedimentar que endureceu. Com o passar do tempo, as paredes da cratera colapsaram pela ação da erosão. . An inverted crater. A regular impact crater on Mars was filled with sedimentar material that hardened. As time passed, its walls colapsed with the action of erosion. .

Depósitos aluvionares erodidos. Cidade de Samaipata - Bolívia. Sua formação pode estar relacionada à uma mudança rápida do nível de base, o que pode ser influência da tectônica recente ou de alterações do clima. Ou ambos. Destacam-se os dois níveis de materiais grosseiros, e a morfologia dos pináculos esculpidos pela ação das chuvas.
