Continental Drift is caused by the heating and cooling of the Earth’s mantel which makes currents. These currents make the plates slide and move over the liquid and molten rock in the mantel. These currents made by the heating and cooling are called convection currents. The person who developed the theory of continental drift was named Abraham Ortelius in 1956. He thought of this theory by noticing that the land of South America seemed to fit Africa like a jigsaw puzzle. He then thought up that the land

etc.5 Caramelization of sugar starts with the melting of the sugar at high temperatures. The temperature for it is 320 degrees F and 160 degrees C.6 Water is heated through convection‚ which means the hot water rises to the top and the colder water drops to the bottom. When you add sugar‚ the waters constant flow due to convection heating forces the movement of the sugar particles and then caramelization will begin once the water is hot enough. Once caramelization has begun and enough sugar has been

2. How is the colour related to surface temperature of the star? The correlation between the surface temperature of a star and its colour is due to the phenomena known as black body radiation .A star is a black body‚where it aborbs all the radiation falling upon it.AS its temperatures gets hotter thanits surrounding‚the star radiates its on electromagnetic radiation‚known as black body radiation. This radiation is distributed unevenly but contionously through multiple wavelengths of the electromagnetic

Marketing strategies of Samsung in India Scenario in the consumers Durables sector:- Prior to liberalisation‚ the Consumer Durables sector in India was restricted to a handful of domestic players like Godrej‚ Allwyn‚ Kelvinator and Voltas. Together‚ they controlled nearly 90% of the market. They were first superceded by players like BPL and Videocon in the early 1990s‚ which invested in brand-building and in enhancing distribution and service channels. Then‚ with liberalisation came a spate

Mechanisms of Heat Transfer Prepared by: Ms. Ana Antoniette C. Illahi 1 Conduction • conduction (or heat conduction) is the transfer of thermal energy between regions of matter due to a temperature gradient. Heat spontaneously flows from a region of higher temperature to a region of lower temperature‚ and reduces temperature differences over time‚ approaching thermal equilibrium.

as well as the pit of the fruit as the core. Second‚ the outer core of the earth rotates. Absolutely this is factual. According to Dr. Pamela Gore‚ “extremely high temperatures in the liquid outer core drive a circular transfer of heat known as convection currents. The fluid core‚ with a radius of 2200 miles‚ is always in motion‚ spinning once a day at about 550 miles per hour at the outer edge of the equator. The exact motion of the outer core fluid is not fully understood. Some researchers have
