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).
Tropical rain forests occur in regions near the equator. The climate is always warm (between 20Â° and 25Â° C) with plenty of rainfall (at least 190 cm/year). The rain forest is probably the richest biome, both in diversity and in total biomass. The tropical rain forest has a complex structure, with many levels of life.
