Sediments become rocks by lithification. 1  compaction-lithification occurs as the weight of overlying sediments and rocks squeeze the sediments together into rock. 2  cementation-precipitates from groundwater and the growth of secondary minerals between the fragments may cement the rock.ediments become rocks by lithification. 1  compaction-lithification occurs as the weight of overlying sediments and rocks squeeze the sediments together into rock. 2  cementation-precipitates from groundwater and the growth of secondary minerals between the fragments may cement the rock.
Weather in Mangrove Forests can ranges drastically because of their location in mainly tropical climates around the world. Most of the mangrove forestation is in the Indian Ocean, whether it be on the coasts of India or surrounding the islands of Indonesia (see Locations of Forests).
Mangrove forests grow on tropical coasts with soft soils and are flooded twice daily by the tide. They are important nursery areas for many species of fish. Mangroves and coral reefs have a symbiotic relationship â the reef protects the coast where the mangroves grow from being eroded by the sea, and the forest traps sediment washed from the land that would otherwise smother the reef.
