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.
The Effects the Moon has on Earth As the moon dances along its orbit in uniform motion with the earth, we see it going from a new moon to full moon and back. We normally think that the moon has no effect on us whatsoever, but in reality, we wouldn’t be where we are now without the moon. The effects the moon has on the earth are ocean tides, the length of our day, months, and animal behavior. The moon tries to pull the earth closer with its gravity. But with the earth being three times more massive than the moon, it is able to stay in place.
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.
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.
These estimates are used largely to guess the mass of asteroids and comets. They are just general guesses made when there is no other information available to help determine the mass. These guesses are more accurately formed as the objects pass by other massive objects like planets where the effect of the planets mass on the direction of the object and the speed of the object can lead to a much more accurate predictor of mass. In no case is an objects spin used in the equations to determine mass. Only the rate at which other objects spin around it.
Looks like a real solar system. It is use to illustrate the relative positions and motions of the planets and other objects/particles in our solar system. The principal components/parts of it are the large bulb that is use to represent the sun which is the center of our solar system ,those round objects as the nine different planets or bodies in orbit the sun and that are bounded by gravity, its body and the stand that support the large bulb. The four small inner objects are use to represent Mercury, Venus, Earth, Mars that are also called terrestrial planets which are composed of rock and metals. There are also four outer objects which are use to serve as the gas giants.
All of a sudden, the moon no longer follows the same course each orbit. Thus, the statement that the moon travels in a specific course “x” as it orbits the Earth is no longer an exceptionless
Phobos will eventually crash into Mars or break up and form a ring around the planet. Deimos (which means fear) was named after the Greek God Deimos who was the twin brother of Phobos. Deimos is the outer moon so it is further away from Mars and takes about 30 hours to orbit. It is small and lumpy and has lots of craters and is covered in dust and loose rocks. Although it has many craters it’s surface is much smoother than Phobos’ Deimos has an average radius of 6.2
Writing in the journal Nature, David Charbonneau at the Harvard-Smithsonian Centre for Astrophysics describes how his team used a suite of eight amateur-sized telescopes to spot the planet as it moved across the face of its star, which is less than 0.5% as bright as our own sun. The telescopes picked up a slight dimming in light from the star as the waterworld, named GJ1214b, passed in front of it every 1.6 days. The planet has a radius 2.7 times as large as the
The ice crystals from the cloud refracts the light from the sun or moon, creating a halo. 17. How do geostationary satellites differ from
