Physical Science Chapter 17 Notes The Moon Our calendar is tied to the phases of the moon. 29.5 days to circle the Earth. July 20‚ 1969 Apollo 11 landed on the moon. The astronauts placed a reflector to reflect the ray of an Earth-based laser beam. Determine the rate of continental drift Detect any change in the location of the North Pole Determine the orbit of the moon more accurate Moon is 2nd brightest object (Sun being the first) Standing on the moon‚ you would see a sunrise and sunrise

starts high above the earth’s atmosphere. The sun emits a continuous stream of ionized gas during its solar flares. This gas consists of electrons‚ protons and helium nuclei. The stream of gasses leaving the sun is known as the solar wind. As the solar wind approaches Earth‚ the particles are influenced by the Earth’s magnetic field and are guided toward oval zones around the magnetic poles. The solar wind particles then collide with air molecules in the upper atmosphere. The collisions impart energy

(Part B) Solar power is not an entirely reliable source of power as it relies on the availability of the sun‚ however‚ using solar power to run some of the smaller‚ non-essential items would reduce the use of electricity generated by fossil fuels. Solar panels can be installed on the roof using tilt frames and facing as closely to north as possible to maximise their efficiency. Where roof mounted panels are not possible a dedicated solar powered hot water system would reduce

Aside from the media influence‚ there are also “historical” and “scientific” theories that support the end of the world‚ none of which are very credible. The theories of 2012olgy and the end of the world include predictions from the Maya calendar‚ solar flares‚ Planet X‚ polar shift‚ and galactic alignment. Thousands of years ago (AD 250) the Maya culture was very advanced for their time. They had a fully developed spoken and written language‚ advancements in architecture‚ art‚ and mathematical

“Nonrenewable energy resources include coal‚ oil‚ and natural gas.” However‚ they are nonrenewable‚ meaning that these resources cannot be regenerated. There are alternatives‚ though‚ that can be used in their stead; some of which are wind turbines‚ solar energy‚ ethanol‚ hydropower‚ geothermal energy‚ biomass energy‚ and ocean energy. The video discussed not only the benefits of some of these fossil fuel alternatives but the challenges faced when using and managing them. The benefits appear endless

Alternative energy sources such as solar‚ hydroelectric‚ geothermal and wind energies can be used‚ to conserve the planets limited natural resources. Alternative energy is the use of another energy without the burning of fossil fuels and break up on atoms. Solar energy can be used to operate cars and provide electricity for homes and businesses.

heating of water to the modern solar cells of the present day. The sun‚ creator of energy forms The sun isn’t just the mother of all life; it also creates almost all of the other energy forms. Most of the energy forms are just indirect solar energy. Waterpower exists because the sun makes the oceans to become steam so that the water can flow back as rivers‚ with enormous power. Wind power exists because different parts of the atmosphere absorb different amounts of solar heat and then comes into collision
