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. Mangrove forests thrive near the mouths of large rivers where river deltas provide lots of sediment (sand and mud). Mangrove roots collect sediments and slow the water's flow, helping to protect the coastline and preventing erosion. Over time, the roots can collect enough debris and mud to extend the edge of the coastline further out.
