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.
In 1991 the lagoon was declared as natural reserve (Reserva Natural Laguna de Apoyo). The lagoon and the crater are shared by the districts of Granada and Masaya. The northern and southern sectors are in the districts of Catarina and San Juan de Oriente, which are part of the department of Masaya.poyo Lagoon. In the center of the Nicaraguan Pacific coast, in the middle of the long volcanic chain which runs through the country from north to south, there is a wide and extended crater in a form of an inverted cone, and in the center of it there is one of the most beautiful lagoons in Nicaragua: the Apoyo Lagoon.
