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.
Peninsula. 1  A peninsula is a piece of land that is surrounded by water from three sides. 2  For example the southern part of India is a peninsula as it is surrounded by the Arabian sea, Bay of Bengal and the Indian ocean and is joined to land on the fourth side. 3  Another example is the State of Florida. A mountain is the highest landform on the surface of the earth. 2  It is usually found to be conical in shape with steep sides and a pointed tip called a peak. 3  As compared to their surroundings, mountains are high points on the surface of the earth.
