focussing. Some Muggle telescopes have these controls too‚ but this magical telescope refocusses automatically. There’s a button for measuring the observed size of a celestial body as seen with the naked eye and another button for measuring the albedo of various parts of a celestial body. The lenses have scratch resistant and break resistant charms on them. Now these features could be easily imitated by Muggle telescopes‚ but they’re not the most impressive things about this model.

Temperature is one of the weather elements and measures the degree of hotness and coldness in a place. The temperature of a place is affected by a number of factors such as latitudinal location‚ seasonal variations‚ albedo of the place‚ contrasts between land and sea and elevation. Latitudinal location has the strongest influence on the climatic conditions on a macro/global scale. The rest of the factors then serves to modify these influences and are secondary‚ operating at a smaller scale. Latitude

GG310 OCEANOGRAPHY Evaluate the geological evidence for so-called ‘Snowball Earth’ glacial episodes in the Precambrian and the hypothesis that these episodes were critical in the evolution of complex life. Introduction The hypothesis of Snowball Earth explores the possibility of the Earth’s surfaces having been frozen over during the Cryogenian period. The initial notion was thought to be from the glacial deposits which occurred around the world parallel to the same time frame. This led scientist

Global dimming‚ a gradual reduction in the amount of global direct irradiance at the Earth’s surface‚ has partially counteracted global warming from 1960 to the present.[55] The main cause of this dimming is aerosols produced by volcanoes and pollutants. These aerosols exert a cooling effect by increasing the reflection of incoming sunlight. The effects of the products of fossil fuel combustion—CO2 and aerosols—have largely offset one another in recent decades‚ so that net warming has been due to

darker land and water surfaces that were beneath the snow and ice‚ and these darker surfaces absorb more of the Sun’s heat‚ causing more warming‚ which causes more melting‚ and so on‚ in a self-reinforcing cycle. This feedback loop‚ known as the ice-albedo feedback‚ amplifies the initial warming caused by rising levels of greenhouse gases. Can you think of a negative feedback mechanism? A good example of a negative feedback mechanism will be if the increase in temperature increases the amount of cloud

Investigation 2: How and why do microclimates vary between coniferous and deciduous woodland areas in the Bon Nant Valley? Hypothesis 1: There will be a significant difference in air and ground temperature in deciduous and coniferous woodlands in the Bon Nant Valley Null hypothesis: There will be no difference in air and ground temperature in deciduous and coniferous woodlands in the Bon Nant Valley I believe that this hypothesis will be proved correct as coniferous and deciduous woodlands

Daisyworld Daisyworld is a mathematical model that yields hypothetical examples of planetary self- regulation as a result of physical feedbacks between life and its environment. This balance between ecosystem mechanisms and variations governs the spatial coexistence of areas of dominance between daisy species and their mutations or adaptions. This theory is an independent model‚ related to the Gaia hypothesis‚ that was introduced by James Lovelock and Andrew Watson in a paper published in 1983

detection was in 1953.[1] EME communication tech has many challenges to make it hard to achieve. The first challenge is the path loss. The distance between the moon and earth is 380000 kilometres‚ so the whole path distance is 770000 kilometres. The albedo of the moon is very low‚ that signals return from the moon maximally 12% but usually closer to 7%. A radio signal from send and return takes about 2.5 seconds. As the path loss is 252dB‚ it is easy to think out how hard it is to build an EME communication

Mary Mitchell June 25‚ 2014 Env 101 EC Climate Change Paper What I Think Is Causing Climate Change Upon completing the summer course of environmental science‚ I have learned plenty of information about the environment around us. I learned that there are many factors that can cause climate change in the world. I now know that climate change isn’t just caused by people in the world‚ or just the world changing slowly. I believe that the change is a combination of both humans and the environment
