  • With 25 million inhabitants, Mexico City is the largest city in the world; it's therefore no surprise that it has so much to offer - from intriguing modern attractions to a variety of ancient cultural wonders. The roots of Mexico's capital lie in its historic centre, which is home to a number of museums, galleries and landmarks; visitors can also experience various religious festivities, cultural events and the 'spirit' of the city by spending time wandering through its centre. Some of Mexico City's top attractions include the National Museum of Anthropology, the Templo Mayor and the Catedral Metropolitana, which now dominates the city's main square, the Zacolo. What's more, Mexico City offers an exquisite opportunity for children to partake in its cultural splendour. The Papalote Children's Museum, for example, holds an array of treasures and is one of the most visited scientific museums in the world.
  • If you're looking for excitement, culture, and perhaps the best margaritas you've ever had, head to Mexico City.
  • As 'the largest city in the world' Mexico City has more than a bit of excitement in store for you

Inland Taipan info. 3 - 0 views

  • The Inland Taipan hunts during the early morning so that it avoids the heat of the day in the numerous small cracks and dry riverbeds
  • The Inland Taipan is a top apex predator and uses its habitat well.  It traps various smaller organisms in the small cracks and crevasses to catch its prey.

  • basic laws of physics dictate that energy is conserved and can only be changed from one form to another or into matter.
  • Fuel, on the other hand, is the accumulation of matter and therefore represents a store of energy.
  • released in the form of heat when the fuel is burned in chemical or nuclear reactions

  • cannot be reversed to regenerate the original fuel mass
  • a fuel problem does exist
  • If the supply of fuel is finite, not only will there be no energy supply when the fuel is exhausted

      Finite means: a form of a verb that can occur as the head of a sentence. In Sam wants to leave, wants is finite, leave is non-finite.
  • all other processes that depend on it will cease
  • Several factors combine to make the problem an urgent one
  • World population
  • demand for energy will also increase
  • coal, oil (petroleum), natural gas, uranium, and fuel wood—is limited and insufficient to sustain rapid rates of development.
  • debate about the exact length of time available before the effects of a worldwide shortage become apparent
  • shortage will occur.
  • geothermal energy, hydroelectric power, peat, ocean thermal energy, solar energy, tidal energy, wind power, and fuel wood.
  • replenish themselves naturally in a relatively short time and will therefore always be available.
  • Renewable energy resources
  • indirectly responsible for many other renewable energy sources.
  • ocean currents and winds are results of the uneven distribution of solar radiation over the Earth's surface
  • winds in turn produce waves whose energy can be utilized
  • windmills and wind power
  • ocean thermal energy, solar heating of the upper layers of the ocean produces temperature gradients that can be harnessed to generate electricity
  • Sun also powers the hydrologic cycle, in which ocean water is evaporated, transported over the continents, and precipitated as rain or snow to form rivers
  • flow energy produces hydroelectric power.
  • energy locked in such renewable fuel sources as wood and peat is derived from the Sun by the process of photosynthesis.
  • renewable energy source is geothermal energy
  • arises through the leakage of heat from the Earth's interior to the surface
  • over the entire surface of the Earth at a very low average rate, leakage is much higher in certain locations.
  • Yellowstone National Park
  • Iceland, Italy, and New Zealand.
  • possible to tap the heat and use it for human purposes.
  • Nonrenewable resources originate from two processes: (1) photosynthesis, which occurred many millions of years ago, followed by the fossilization of the plant and animal life that resulted, and (2) the formation of the Earth itself.
  • fossil fuels—coal, oil (petroleum), and natural gas;
  • produced the fuels for nuclear energy, such as uranium for fission and lighter elements for fusion
  • irreplaceable fuels represent an energy capital that must be invested wisely.
  • A cleaner-burning fuel than oil, natural gas seemed to be in abundant supply at the turn of the 21st century and, with the greatly enlarged network of gas pipelines, was rapidly growing in use.
  • nearly total dependence on fossil fuels and hydroelectricity ensures that efforts to solve energy problems by switching to alternative sources will have to overcome a great deal of inertia, both economic and psychological.
  • sources as solar power, wind power, and synthetic fuels suffer from the serious drawback that few major installations now exist.
  • handicapped by the engineering problems of converting the energy to a form useful to human beings.
  • solar energy reaches the top of the atmosphere in amounts 10,000 times greater than all human production of energy, it reaches the Earth's surface at rates of only about 80 to 250 W/m2, and considerably less on cloudy days.
  • arge-scale system based on solar-collector panels will be physically huge, causing problems of maintenance and land use
  • Wind power, wave power, and ocean-thermal-generation sources suffer from similar difficulties

Drugs in sport-Key text - 0 views

  • Only the gifted, only the dedicated, only the best will win.
  • Modern sport is plagued by suspicions that many top athletes resort to drug-taking – doping – to enhance their performance. They use anabolic steroids, human growth hormone, erythropoietin (EPO), beta-blockers, stimulants or diuretics.

  • mirror focuses the sunlight to strike the pipe
  • ...35 more annotations...
  • gets so hot that it can boil water into steam
  • team can then be used to turn a turbine to make electricity.
  • California's Mojave desert, there are huge rows of solar mirrors arranged in what's called "solar thermal power plants"
  • this idea to make electricity for more than 350,000 homes
  • problem with solar energy is that it works only when the sun is shining
  • cloudy days and at night, the power plants can't create energy.
  • solar plants, are a "hybrid" technology
  • daytime they use the sun
  • night and on cloudy days they burn natural gas to boil the water so they can continue to make electricity.
  • form of solar power plants to make electricity is called a Central Tower Power Plant, like the one to the right - the Solar Two Project.
  • Sunlight is reflected off 1,800 mirrors circling the tall tower
  • mirrors are called heliostats
  • move and turn to face the sun all day long
  • light is reflected back to the top of the tower in the center of the circle where a fluid is turned very hot by the sun's rays.
  • luid can be used to boil water
  • make steam to turn a turbine and a generator.
  • We can also change the sunlight directly to electricity using solar cells.
  • Solar cells are also called photovoltaic cells
  • PV cells for short
  • be found on many small appliances
  • calculators
  • even on spacecraft
  • first developed in the 1950s for use on U.S. space satellites
  • made of silicon, a special type of melted sand.
  • sunlight strikes the solar cell, electrons (red circles) are knocked loose
  • move toward the treated front surface (dark blue color)
  • electron imbalance is created between the front and back
  • two surfaces are joined by a connector, like a wire, a current of electricity occurs between the negative and positive sides.
  • individual solar cells are arranged together in a PV module and the modules are grouped together in an array.
  • arrays are set on special tracking devices to follow sunlight all day long.
  • electrical energy from solar cells can then be used directly
  • used in a home for lights and appliances

List of breakdance moves - Wikipedia, the free encyclopedia - 0 views

  • The Top Rock is a combination of steps done while standing up. This is the entry dance that Bboys and Bgirls use to start their set. These steps are done before you do a power set or before you go down to the floor. This is the breaker's chance to show how well he or she can rock the beat and/or make gestures to intimidate their opponent
  • The foundational footwork sequence. Although many variations exist that either add or subtract steps in the sequence, the 6-step is the most basic form of downrock.
  • A Power Move is any type of move in Bboying which requires spinning and/or rotating in a way that can be done so in multiple rounds. All Power Moves (or series of a type of Power Move) can be connected in combos to form a "Power Combo". Breakers that use mostly Power combos in there sets are commonly known as "Power Heads". Example: Flare-Air Flare-Elbow Air Flare-Air Flare-1990...etc Or-Air Flare 1.5-Babymill-Windmill-Swipe-Windmill-Halo-Headspin...etc The possible number of combinations are endless and only limited by stamina, strength and imagination. In 2002 The Guinness Book of World Records began tracking number of power move rotations for their world record standings. At that time Canadian Gregory Burbidge broke records for Air Flare, Headspins, and Elbow Airflares. American Lauren Jacob held the record for Chair Flares. American Laura Derrick held the record for Tappingmills. Nicole Jones (nationality unknown) held the record for Munch Airflares. In 2004 Guinness removed these titles from their records. At the time Gregory Burbidge was the only one who still held records from the original group.
