Life's a Beach Seashores are unique areas and the organisms that live in them face many challenges. There are four types of shores. Sandy shores are covered in sand. Sand is made up of fine grains of rock, coral and shells. Muddy shores are covered with mud.
Rocky shores have large rocks and rocky cliffs.
Shingle shores are covered in pebbles and small rocks. All of these types of shores may have unique characteristics, but they all have one thing in common, intertidal zones. The intertidal zone or littoral zone is the area of shoreline between the high tide and low tide marks. For part of the day, it is covered in water and for part of the day it is dry or partially dry. In addition to changes in water levels, the intertidal zone can see great changes in humidity, temperature and wave pressure during the course of a day.
