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.
Fjord Landforms Have 3 Main Characteristics: A long, narrow inlet; Steep rock formations on each side; Formed by glacier movement; Example of a Fjord Landform: Sognefjord, Norway The Fjord picture above is from Norway. What is a Fjord Landform? A fjord is an inlet that is long and narrow in shape, with steep cliffs or other steep rock formations on each side. A fjord is formed by the movement of a glacier that cuts rock formations, forming steep ridges or cliffs on each side of a valley. The valley fills with water from a nearby ocean or sea, leaving steep rock formations above water on either side.
