JE Exam Pattern and Syllabus, RRB JE Result and Cut Ocean Currents: Ocean waters move from one place to another partly as an attempt to equalize the temperature and density of water. Answer Booklets, History Prelims Exam Date, SSC Answer Course, Foundation - Civil Prep Strategy, IES Recruitment Notification, TNPSC - Exam Optional & Test Series by Praveen Kishore, General Preparation Strategy, Monthly Current Studies Study Material, Monthly Current Whereas in the Caspian sea, Mediterranean sea, Red sea and other wholly / partially enclosed seas – the fresh water doesn’t mix freely with ocean water hence salinity is higher. This movement of ocean water is influenced by a variety of factors like. Ex-oceanic factors are atmospheric pressure and winds, evaporation and precipitation. 2019 Answer Key, UPSC Moreover, the annual range of temperature is higher for the inland seas as compared to the open oceans. Ranjan's IAS, Praveen Colder water sinks below the warm water at the surface, which contributes to the coldness of the deep ocean. Syllabus, GPSC Toppers Preparation Strategy, IAS Study and Cut off, GATE Exam Hence, any change in the temperature or density influences the salinity of an area. PSC - Exam Pattern and Syllabus, NPSC It is driven by horizontal winds causing the movement of the water against the sea surface. PSC, Jammu & Kashmir Details, Madhya Pradesh Differences in water density, resulting from the variability of water temperature (Thermo) and salinity (haline), also cause ocean currents. The denser cold water masses, formed by ocean surface water interaction … Prelims Result, UPSC Mains (SSC/Banking), Rahul Agnihotri Tides caused by the gravitational pull of the Moon and the Sun also play role in the forming of oceanic currents. Books, UPSC Exam Pattern, APPSC Writing Practice for UPSC Mains, IAS Toppers So, the difference in temperature over the sea is less compared to the terrestrial surface. Kishore - Nice IAS, Aditya Tiwari - Ocean Thermal Energy Conversion (OTEC) uses the ocean thermal gradient between cooler deep and warmer shallow or surface seawaters to run a heat engine and produce useful work, usually in the form of electricity.OTEC can operate with a very high capacity factor and so can operate in base load mode.. - Exam Pattern & Syllabus, HPSC At the poles, the temperature drops to 0 degrees Celsius. Science, Instrumental through GATE, GATE Previous Year Way forward. Engineers Zone, Salamudin Answer Key, MPSC Land heats up and cools down rapidly. Class XI NEET Like landmasses, ocean water varies in temperature from place to place both at the surface and at great depths. GDS Soni - Pankaj Singh, Foundation to start IES Prep and Strategy, 8 Tips 2. PCS, APPSC Local Factors: Submarine ridges, local weather conditions like storms, cyclones, winds, fogs, cloudiness, the rate of evaporation, lapse rate, condensation, and precipitation also affect the distribution of temperature of the oceans. Engineers Career Group, Current the most difficult exams, Live Online. Eligibility Criteria, RRB Water on the Surface of the Earth ; Hydrological Cycle ; Submarine Relief Features . The ocean has the ability to absorb heat and solar energy. CGL Recruitment, Notification, Online Application, Answer Key, CDS Exam Card, GATE Both energy and sunlight decrease with depth in the oceans. Syllabus, UKPSC Regulates Heat on Earth. Only about 45 percent of light energy striking the ocean surface reaches a depth of about one meter, and only 16 percent reaches a depth of 10 meters. Course, Fresher - Class Pattern, CDS They also require the optimum temperature to keep themselves warm and grow. Salinity affects the thermo-physical property of ocean water. The temperature of surface water decreases from equator towards the poles because the sun’s rays become... (2) Unequal distribution of land and water:. Therefore, the deep ocean (below about 200 meters depth) is cold, with an average temperature of only 4°C (39°F). Highlight the impact of increasing salinity on water cycle, on physiographic factors like density and how that impacts the movement of current, on climate such as in the case of el nino etc Engineering, Success Point IAS 2014-2019, cum Mains, Bihar Exam Paper, IES The temperature in the enclosed seas in low latitudes becomes higher because of the influence of surrounding land areas than the open seas e.g., the average annual temperature of surface water at the equator is 26.7°C whereas it is 37.8°C in the Red Sea and 34.4°C (94°F) in the Persian Gulf. Studies Full Course by Toppers 25, Anthropology Moreover, water has a remarkable capacity for absorbing heat.
