Bioclastia
- Desencadeada pela ação dos seres vivos.
Fig. 2 - Crescimento de raízes em fraturas de rochas.
Fig. 1 - Cavidades em rochas do litoral escavadas por moluscos bivalves.
Crioclastia
- Desencadeada pela ação do gelo.
Fig. 4 - Efeito da água que penetra nas fissuras e nos poros das rochas, ao congelar.
Fig. 3 - Desagregação das rochas devido à expanção da água, por congelação, na Serra da estrela.
Termoclastia
- Devido á ocorrência de elevadas amplitudes térmicas.
Fig. 5 - Fragmentação de uma rocha por efeito de variação térmica.
Haloclastia
- Devida à evaporação de água salgada.
Fig. 6 e 7- Efeito da haloclastia em rochas.
Esfoliação/ Dinjunção esforoidal
- Resulta do alívio de pressão.
Fig. 9 - Diáclases.
Fig. 10 - Disjunção esferoidal.
Fig. 8 - Diáclases no granito na serra das Mesas, Sabugal.
