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).
The tropical evergreen forests usually occur in areas receiving more than 200 cm of rainfall and having a temperature of 15 to 30 degrees Celsius. They occupy about seven per cent of the earth's land surface and habours more than half of the worldâs plants and animals.
