### formation:

Beach
* Many beaches are made of sand, but some beaches are made of gravel
  - of soft, white sand and lapped by clear water
  - contain an association of several mineral types
* Most beaches are of light colored sand
  - consist of fine, clean sand
* Some beaches allow animals at specified times
  - are notorious for their rips
* Some beaches are part of coasts
  - seashores
  - sand on top of hard rock
  - can have rather strong and unpredictable ocean currents
  - contribute to erosion
  - dont have sand just rocks
* Some beaches have dangerous sea creatures like crabs, stingrays, jellyfish, sharks and others
  - irregularities such as under water reefs where rips always form
  - man-made infrastructure, such as lifeguard posts, changing rooms, and showers
  - separate areas for swimming and other water sports
  - two and even three berms that resemble terraces
* Some beaches provide habitats
  - nest habitats
  - require surfers to use leashes
* affect our everyday lives.
* are a huge part of Southern California living
  - all coral, with chunks which can be sharp
  - an important aspect of the Florida economy, attracting tourists throughout the year
  - associated with summer in Western culture
  - beaches, only different
  - changed in shape chiefly by the movement of water and wind
  - coastal parks which act as magnets for millions of tourists
  - constantly in motion
  - gentle slopes that contain loose sediment, such as coarse gravel, cobbles, and sand
  - interesting as ecosystems because they are in a state of constant flux
  - located in state parks
  - only one type of coastal setting
  - part of shores
  - places
  - recreational areas
  - sandy, gravelly, or cobbly shores washed and rewashed by waves
  - shore protection
  - shorelines
  - subject to natural accretion and erosion
  - usually narrow, with white sands, full of palm trees and transparent waters
  - virtually nonexistent in places
  - vital environmental, cultural, recreational, and economic resources
  - wide and strewn with fine sand
* attract turtles.
* can be great places for swimming, making friends with nature and playing in the sand
  - hundreds of kilometers long or very short
  - popular on warm sunny days
  - wide and flat or narrow and steep
* change from season to season
  - with the seasons
* come in a variety of sizes, shapes, and compositions
  - many varieties
* disappear as sea levels rise.
* follow a characteristic profile shape based on the wave climate and the types of sediments.
* get sand from both the ocean and the land.
* have palm trees
  - sandy shallow shorelines
* have the function of keeping water clean
  - ocean to absorb the heat emitted by the sun
  - white as well as black sand
* is applied to the skin like a body lotion.
* meshing operations change the habitat of some coastal areas, increasing mortality of sharks.
* naturally respond to erosion by migrating landward.
* occur when sand, gravel, and other loose material are deposited by waves along a shore
  - where sand is deposited along the shoreline
* pheromone scented product that attracts the opposite sex.
* play a unique and vital role in the nation's environment, economy and way of life
  - critical roles in many plant and animal life cycles, and support unique biodiversity
* provide some protection to residents living near the ocean.
* show a large variety in morphology from coast to coast and in time at a particular location.
* tend to develop gentle curves punctuated by sharp cusps.
* usually generate next to oceans and cover all nearby shorelines.
* vary from long stretches of white sand to rocky shores with hidden coves
  - widely in physical type and characteristics
* worldwide are most important nesting sites for the green sea turtle.
+ Summer:
  * A 'beach' is an area of lakeshore or seashore which is fairly open, slopes smoothly to the water, and is free of trees, large boulders, or anything else which might make walking difficult or impossible. Many beaches are made of sand, but some beaches are made of gravel. Beaches are easy natural landing and launching places for boats, including landing craft specially made for beaches.
