The rocky shores occur on a steep coast without large amounts of sediment. A tide pool is created when a low tide occurs and exposed the organisms that live there. ]]> 2019-04-30 15:25:02 UTC https://padlet.com/20meninnorm/j9htgq1q81f0/wish/355484665 19pamintuanaj https://padlet.com/20meninnorm/j9htgq1q81f0/wish/355484680 The Rocky Inter tidal Zone, sometimes called the "littoral zone" is home to the highest high tides and lowest low tides. Constant wave action occurs here and is mostly exposed to air which causes water loss so organisms of this habitat have adapted. ]]> 2019-04-30 15:25:03 UTC https://padlet.com/20meninnorm/j9htgq1q81f0/wish/355484680 20meninnorm https://padlet.com/20meninnorm/j9htgq1q81f0/wish/355485519 The rocky intertidal zone consists of large and sometimes jagged rocks. Steeper coastlines are often the result of more recent tectonic activity, composed of minerals such as granite.

☸Burrowing
☸Clumping together into groups
☸Clinging to and attaching to rocks
☸The use of shells and other forms of protection
☸Run-and-hide strategies
☸Verticle zonation]]> 2019-04-30 15:34:21 UTC https://padlet.com/20meninnorm/j9htgq1q81f0/wish/355489646 20meninnorm https://padlet.com/20meninnorm/j9htgq1q81f0/wish/355491247 2019-04-30 15:37:19 UTC https://padlet.com/20meninnorm/j9htgq1q81f0/wish/355491247 20meninnorm https://padlet.com/20meninnorm/j9htgq1q81f0/wish/355494299 Every ecosystem consists of limiting factors, which creates a population cap on a species in an area. For the rocky intertidal zone, such factors include:
☸Access to fresh water
☸Oxygen, which is caused by low tide exposing gill dependent organisms to the atmosphere
☸The erosion of rocks and sediments
☸General exposure from low tide, which allows not only for limited oxygen but also for exposure to predators
☸Wave action that may hurt to flora or fauna
☸Nitrogen
☸Space, hence verticle zonation]]> 2019-04-30 15:42:57 UTC https://padlet.com/20meninnorm/j9htgq1q81f0/wish/355494299 20meninnorm https://padlet.com/20meninnorm/j9htgq1q81f0/wish/355497306 Starfish are a commonly found entity in intertidal zones.
