The Changing Tides Phenomenon
Everyday ocean tides rise and fall. This dramatic increase and decrease in the water level affects coastlines and their environments around the world. This phenomenon is caused by the changing position of the sun and moon in relation to the earth. The Earth's tidle buldges track both the moon, and to a lesser degree, the sun. When the tide rises and falls, the shoreline landscape changes. Beaches become larger or smaller depending on the time of day. Rocks become more or less exposed. During low tide, what was once beneath the waves is now exposed beneath the sun. Some of the things involved in this phenomenon are the sun, the moon, the earth, the ocean, people, shorelines, and marine life. The frameworks of this phenomenon are the interactions and relationships among these things. These relatoinships include the number of people to the relation of the size of the beach and the amount of shoreline exposed in relation to the sealevel and the position of the sun and moon. The clockworks invloved in this phenomenon are controlled by the constant rotation of the earth and its position to the sun and moon. The changing tides are dependable and always on time.
