the Sun reinforce those of the moon: spring tide * When the moon is at first or third quarter‚ the sun and moon are separated by 90 degrees. The forces of the sun and moon cancel causing: neap tide * Semidiurnal: two high tides and two low tides each day * Diurnal: one tidal cycle per day * In most places tides are mixed. Because of the diurnal contribution‚ there is a difference in height (the daily inequality) between the two high tides in a given day. * The size of wind waves

The Sun and Moon Elizabeth Milam ENG 121: English Composition I Kathy Conner March 5‚ 2012 The Sun and Moon The sun and the moon have both been dated at 46 billion years old. Other than defining time in human experience‚ the sun and moon have very little in common. Their differences range from physical attributes to functions. Since the beginning of civilization‚ both bodies have inspired a fascination in humans. Even though the sun and moon appear to play similar roles‚ they are

darkened my hated freckles which Nana laughingly referred to as angels’ kisses. Sometimes‚ a wave smacked the wall so hard a white foamy spray rose and blanketed me with a cooling‚ salty tasting mist. After a while‚ the waves receded with the low tide revealing a huge peanut butter colored beach dotted with piles of grey rocks. I walked to a place where there was an opening in the sea wall and discovered a steep stairway that descended down to the beach. I ran to Nana’s summer home‚ grabbed an

Here‚ democracy first dawned over the high tide of western colonialism at the end of the last century. Yet in 1989‚ we Filipinos dared to rise against the tide of history and to declare ourselves free‚ the first in all of Asia to break the shackles of Western Colonialism. Even in 1946 when we regained our independence from the colonial powers. As the

Ellen Ryan Biology IA Task G1 Investigation into the biodiversity of organisms at different heights on a rocky shore. PART (1) Ellen Ryan Introduction This experiment was carried out in order to better understand Hong Kong’s ecology and biodiversity‚ specifically focusing on field-based whole organism biology in an area with little human interferences. Method 1. Lay a horizontal transect on the mid-shore (1.75m) 2. Repeat for high-shore (2.25m) 3. At regular intervals of 1m

The crew of the Essex had never ventured into these waters and the whalers were unfortunately unaware of the dangers that awaited them in this uncharted territory. The tides turn on the whalers on November 20‚ 1820; the lookout crew spotted a pod of whales and immediately the harpoon crew boarded

This research was processed through The Keystone Predator model‚ based upon experiments preformed in the 1960’s along the rocky shore of Washington. This environment is the region between the high and low tide levels of a rocky shoreline. The community and population of the environment must survive the cold air and the nature of waves. 9 different species and their populations were simulated. The simulated environmental community contains 4 species of mobile consumers‚ 3 species of filter feeders

Overview Plankton is a microscopic drifting organism present in most of the water bodies around the world. There are three categories of plankton‚ but only Phytoplankton and Zooplankton are of our interest. Phytoplankton is the primary producer and forms the base of food chain in most water bodies. Among these phytoplankton groups‚ there are some species that harm aquatic organisms mechanically or by toxin production either at low concentrations or by forming high concentration blooms known as Harmful
