Weathering Process. The weathering process occurs when rocks are exposed to the hydrosphere (water) and atmosphere (air).  These agents can change the physical and chemical characteristics of rocks.  As rocks are broken down (weathered), they can be classified as different types of sediments, which are: o boulders, cobbles, pebbles, sand, silt, clay, and colloids. See page 6 of the Earth Science Reference Tables explains the sizes of each of these sediments.
Lagoon is a water body that is formed near coastal areas. It is shallow and has a small link with sea or the ocean though it is also separated from the ocean water with reefs or a low sandbank. Arial view of a lagoon.
They are lined with clay or a synthetic liner to prevent leakage into the soil and ultimately groundwater or other water sources. Lagoon systems use biological, physical, and chemical processes to treat the wastewater during its storage period before dispersal onto crops, pasture ground or other types of land.Most of the treatment occurs naturally by anaerobic or aerobic bacteria, depending on the design of the lagoon system.ver a 20 to 50 day period wastewater solids separate into layers, with oils and floating materials on top and heavy sludge on the bottom. The top layer seals oxygen out of the lagoon system, providing the anaerobic conditions for bacteria to treat the wastewater.
