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.
These events change the surface of the Earth by creating different landforms. A landform is a term that describes the shape of a natural land feature. Landforms are created by different forces of nature. For example, mountains, oceans, valleys and deserts can be called landforms.A group of landforms in one area makes up a landscape.The view from an aeroplane or from the top of a hill gives a good picture of a landscape.or example, mountains, oceans, valleys and deserts can be called landforms.
