Astronomy 1307 | In the Solar System today, we have the four inner planets: Mercury, Venus, Earth, and Mars, along with two small moons. We also have the four outer planets: Jupiter, Saturn, Uranus, and Neptune. Along with these, we also have asteroids, from the asteroid belt, meteorites, and comets. 1. They escape from each other. 2. They crash into each other 3. **Why does the Moons surface have many craters and Earth's does not? Atmosphere on Earth, but not on Moon. We now come to the Moon A) Moon does rotate, or spin B) The period of time it takes to roate, is equal to the time it takes to orbit the Earth C) Because these two period are equal, we only see the visible side of the Moon Oceans on the Earth rise and fall periodically (twice a day, in other words, the ocean moves four times a day)= 2 high tides, 2 low tides They are a gravitational effect. 1) FISSION THEORY- The Earth was very hot and spinning rapidly. 2) CAPTURE THEORY- Moon is captured by the Earth because it came too close. 1. 2. 3. 4.
Physicists challenge classical world with quantum-mechanical implementation of 'shell game' Inspired by the popular confidence trick known as "shell game," researchers at UC Santa Barbara have demonstrated the ability to hide and shuffle "quantum-mechanical peas" -- microwave single photons -- under and between three microwave resonators, or "quantized shells. " In a paper published in the Jan. 30 issue of the journal Nature Physics, UCSB researchers show the first demonstration of the coherent control of a multi-resonator architecture.
This topic has been a holy grail among physicists studying photons at the quantum-mechanical level for more than a decade. The UCSB researchers are Matteo Mariantoni, postdoctoral fellow in the Department of Physics; Haohua Wang, postdoctoral fellow in physics; John Martinis, professor of physics; and Andrew Cleland, professor of physics.
According to the paper, the "shell man," the researcher, makes use of two superconducting quantum bits (qubits) to move the photons -- particles of light -- between the resonators. First water map of Earth's leaky surface. Michael Marshall, environment reporter (Image: Tom Gleeson/Geophysical Research Letters) The map above (click to enlarge) is the first-ever global survey of Earth's permeability: essentially, how leaky it is. It shows how easily water passes through surface rocks, which will help us understand the planet's water cycle and predict the sustainability of underground water sources. Crucially, it could help reveal the hidden underground movements of 99 per cent of unfrozen fresh water - water which is not taken into account in computer models used to predict the climate.
The map was put together by Tom Gleeson of the University of British Columbia in Vancouver, Canada, and his colleagues. Permeability varies over 13 orders of magnitude, so the figures are not very precise, but they offer a rough picture. At the moment we don't know how much water is hiding underground, or where it is. Groundwater makes up 99 per cent of the fresh unfrozen water on Earth. Plate Tectonics. Continental Drift: Any major new idea in science appears to lead instantly to a search of the past for those who might once have proposed similar concepts and with whom the current proponents should therefore share the credit. In the case of plate tectonics, the primary candidate is obvious: Alfred Wegener of Germany, who explicitly presented the concept of continental drift for the first time at the outset of the 20th century. Though plate tectonics is by no means synonymous with continental drift, it encompasses this idea and derives much of its impact from it.
In 1858, geographer Antonio Snider-Pellegrini made these two maps showing his version of how the American and African continents may once have fit together, then later separated. There might have been predecessors even to Wegener. Plate Tectonics: Plate tectonics is a theory dealing with the dynamics of the Earth's outer shell, the lithosphere. At convergent boundaries, plates move toward each other and collide. Water on Earth. Introduction The presence of water as solid, liquid, and gas is a feature that makes the Earth unique in the solar system and that makes possible life as we know it. The biosphere that has evolved on Earth has been strongly influenced by the rather special chemical and physical properties of water, including water's ability to store heat, act as an inert solvent, and transport nutrients.
The transport of water and the energy exchanged as it is converted from one state to another are important drivers of our weather and climate system. The water cycle is the largest chemical flux on Earth (see Figure 1) .Figure 1. Water is continually moving around, through and above the Earth as water vapor, liquid water, and ice. In today's presentation, we will use a general approach to understanding the global water cycle that can be applied to any element cycle.
Distribution of Global Water As shown in Table 1 below, over 97 percent of all water on Earth is found in the oceans. Table 1. Ocean 1370 No. The best AMERICAN and GERMAN news finder | SHOUTing GORIlla. Primatology.net | We ain’t monkeyin’ around here. Anthropology.net | Beyond bones & stones. TED.
