Ocean, Meteorology and Atmosphere Assignment Example | Topics and Well Written Essays - 750 words

Ocean, Meteorology and Atmosphere - Assignment Example The movement of sand on a beach environment is a complex process controlled by natural processes such as winds and storms as well as human-induced factors such as destruction of dune vegetation as well as construction structures such as jetties, groins, and seawalls among others. 13. Distinguish between a flood current and an ebb current. Of flood current, ebb current, high slack water, and low slack water, when is the best time to navigate a boat in a shallow, rocky harbor? A flood current is the tidal current moving from the sea to the shore while ebb current is the tidal current receding seawards. It is best to navigate a boat in a shallow, rocky harbor during low slack tides. 14. Are estuaries associated with submerged or emergent coasts? Yes, Estuaries are associated emergent or submergent coasts with the ones along submergent coastlines being larger while the ones along emergent coasts are smaller. 4. How does the Coriolis effect modify air movement? The Coriolis effect normally modifies air movement by deflecting the air to the right of its motion in the Northen hemisphere and to the left of its motion path in the Southern hemisphere. 9.Describe the principle of the aneroid barometer. An android (no liquid) barometer is made of evacuated metal chambers that work by compressing with the increase in air pressure.

Twinearth Thought Experiment Term Paper Example | Topics and Well Written Essays - 500 words

Twinearth Thought Experiment - Term Paper Example This concept has failed severally to give the necessary results and thus it should be rejected. People have also tried to use is the notion of extension and intension to solve the problem. This notion although seemed to be the simplest, it actually complicated the whole problem. The terms, which are more problematic, are those having more than one sense like the words rabbit and set (Putnam 1975, 581). It is proposed that treating each sense of a word as a different word can solve this problem of complication. It is due to these complications that the Twin Earth Experiment is preferred over this method. The Twin Earth thought experiment assumes that somewhere on the galaxy there exists a planet identical to earth called Twin Earth. The only difference experienced between Twin Earth and the Earth is the vernacular English spoken in either. These differences are contributed by the uniqueness of Twin Earth (Putnam 1975, 584). It is believed that the chemical composition of the liquid called water on Twin Earth is not H2O but another complicated chemical which we shall assume as XYZ. In this experiment it is believed that XYZ performs on Twin Earth all the functions water perform on earth and it tastes like water. It is also known that at normal temperatures and pressure, H2O is different from XYZ. In addition, it is understood that oceans, seas, and lakes of Twin Earth contain XYZ and that it rains XYZ on Twin Earth. Suppose now that we have two individuals with identical attributes, one from the earth and the other one from Twine Earth. If these individuals exist in the current society in which we can assume that the chemical composition of water is known both on earth and on Twin Earth, each will understand water differently. The one from the earth will understand water as H2O and the one on twin earth as XYZ. Now suppose that these two individuals exist in a time when the chemical composition of water
