powerful. In addition‚ people may not think about how tides are formed. The movement of waves includes information about how waves form‚ how they move‚ what happens when waves interact‚ and some of the effects of waves. When people visit a beach‚ they might realize the daily rise and fall of the water‚ or how high and low tides can get. Tides are caused by the moon‚ sun‚ and the earth and are almost never are the same size or duration. A tide can spread out to be much bigger than what it was

Chapter 15 – Restless Realm: Oceans and Coasts Key Point • Why does ocean water circulate? • How does the topography of the ocean floor change from a continental margin to the mid-ocean ridge? How are the oceans mapped? • How do ocean waves and breakers form? • How sediments are moved along a shore line and what coastal features are formed? • Be able to recognize both depositional and erosional coastal landforms Why should we study the oceans? • 70% of Earth’s

Materials and Methods Study Area Jeram and Remis Beaches are located in West Coast of Peninsular Malaysia (3o13’27”N‚ 101o18’13”E) (Figure1) where semidiurnal tides prevail. The distance between Jeram Beach and Remis Beach is approximately 2 km. The selected study areas comprise approximately 55 ha of intertidal mudflats area. The selection of these sites was based on past history of shorebirds counts reported by Wetland Internationals in 1999-2004 (Li et al 2007) which shows that these sites was

Liverpool landing stage on its east bank and the Woodside and Seacombe landing stages on its west bank. The River has the world’s fourth highest tidal range with up to 10 meter high spring tides and 7 meter high neap tides. Due to the narrowing of the river from over 3 miles wide in parts and the size of the tides‚ speeds of water behind all three landing stages can regularly get up to 7 Knots (8MPH). This causes numerous under currents around all three of the landing stage areas and can sweep a person

THE MARGINAL WORLD The edge of the sea is a place in which wave‚ by wave had broken against the land‚ and where the ocean never rests‚ never stops‚ it is always in constant movement‚ it is always changing‚ and the ebb tide knows extreme parts of the world‚ and it is exposed to different temperatures. Living in there‚ in the shore‚ is difficult for animals only the most hardly and adaptable of them can survive‚ but there is a variety of species in there‚ there are also deep in the sand‚ were they

What is conflict? For me there is no true meaning for conflict‚ the word doesn’t really have any positive meaning; it is just filled with loathsome venom that has spread throughout our world causing antagonism and bitterness towards others. Conflict is a natural part of everyone’s life and is bound to occur in some point in time‚ but there is no justification for people to turn something that can be small and compromised into a vast worldwide crisis for all to see and hear! However not all conflict
