Hint: Pay attention to the units of measure. You may have to convert from feet to miles several times in this assignment. You can use 1 mile = 5,280 feet for your conversions. Many people know that the weight of an object varies on different planets, but did you know that the weight of an object on Earth also varies according to the elevation of the object? In particular, the weight of an object follows this equation:[pic], where C is a constant, and r is the distance that the object is from the center of Earth.
4 outer planets become large enough to accrete dust and gas forming gas giants or 2.. instabilities in the cooler region of solar system cause a collapse of initial interstellar cloud. Random: Kuiper Belt lie beyond Neptune, close to ecliptic, also where most comets(originate from oort cloud) orbit. denser planets are closer to sun, Saturn can float, in differentiated bodies denser materials lie near core, density=mass/volume. Auroral happens due to solar winds displaced poleward by magnetic field. Deepest depression= Mare Crisium on moon.
The word "tides" is a term used to define the alternating rise and fall in sea level with respect to the land, produced by the gravitational attraction of the moon and the sun. To a much smaller extent, tides also occur in large lakes, the atmosphere, and within the solid crust of the earth, by the same gravitational forces of the moon and sun. Tides are the periodic rise and falling of large bodies of water. The moon is important to us because it creates tides. Tides are daily movements of ocean water that change the level of the ocean's surface.The tides are caused by the exertion of gravitational forces by the moon and sun, and the rotation of the Earth.

This is referred to as the Synodic rotation period, whereas the former is the Sidereal rotation period. Now don't confuse this with modern techniques used to estimate the mass of an object by its spin. This kind of measurement is similar to relative dating techniques. The idea is that all things in our solar system are VERY old and that they have all been influenced by roughly the same gravitational forces and that they are mostly the same age. These estimates are used largely to guess the mass of asteroids and comets.
The ice crystals from the cloud refracts the light from the sun or moon, creating a halo. 17. How do geostationary satellites differ from
(The LOP is actually a short segment of a very large circle on the earth which surrounds the GP of the observed celestial body. An observer located anywhere on the circumference of this circle on the earth, measuring the angle of the same celestial body above the horizon at that instant of time, would observe that body to be at the same angle above the horizon.) Sights on two celestial bodies give two such lines on the chart, intersecting at
Kepler's Law is summerized in three smaller laws. First law states the shape of each planet's orbit corresponds to the sun at its center, thus an ellipse orbit would be off-center in the shape. The planet's distance from the sun varies as it moves through the orbit. Second law simply states the speed of a planet is determined by the distance from its sun. The closer the planet is, the faster the speed.
The Geology of the Moon Approximately 4.5 billion years ago a large asteroid struck Earth and thus resulted in the Moon. This impact theory suggests that the collision ejected raw materials which in time became the Moon. With the Moon having no significant atmosphere, it can reserve a good record of the impact history. This information can provide geologists with clues to the history of the Earth. The crust of the Moon is composed of a variation of primary elements, including uranium, oxygen, thorium, potassium, silicon, magnesium, iron, titanium, calcium, aluminum and hydrogen.
It is often difficult to find an exceptionless regularity because there could always be a circumstance under which the law does not hold true. To see why, suppose I am observing the moon’s orbit around the earth and I see that the course is the same each orbit. I believe I have found an exceptionless regularity. Imagine that a meteor was to collide with the moon, and slightly change its course. All of a sudden, the moon no longer follows the same course each orbit.
