The Earth is one of eight major planets and a host of minor planets that circle a fairly average‚ middle-aged‚ main-sequence star. It formed from the accretion of residual material from the gravitational collapse of the solar nebula that produced the Sun. Based on their specific distances from the Sun‚ the planets formed into groups of similar chemical compositions‚ sizes‚ and densities. The four smaller inner planets are of higher density and are composed of a mixture of rock and metal. In contrast

“The Earth has a fever‚ and the fever is rising… We are what is wrong‚ and we must make it right” (Al Gore‚ 2007). In the context of global warming‚ discuss the extent to which you agree with this statement. For the last 2.5 million years‚ global temperature has shifted between cold glacial periods that last for around 100 000 years‚ and warmer interglacial periods that last for around 10 000 years. Right now we are in an interglacial period. 20 000 years ago the Earth was cold. Around 15000 years

The thermocline upwells‚ because the thermocline is the transition layer between the surface layer and the deep ocean currents. The deeper‚ colder water rises from below the thermocline‚ and replaces the not-very nutrient rich surface water‚ with nutrient rich water from below. 5. In El Nino‚ warm waters of the western Pacific migrate eastward and reach the South American coast. The cool nutrient rich water

is: CaCO3(s) + 2HCl(aq) → CaCl2(aq) + CO2(g) + H2O(l) Purpose: The purpose of this experiment is to determine how the surface area of CaCO3(s) affects the rate of reaction by measuring the volume of CO2(g) produced with time. Background: When solid reactants are mixed with liquid reactants only the particles on the surface of the solid will have direct contact‚ or collide‚ to the other liquid reactant particles. When there is more surface area there
