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.
D. the Moon. ID:62096 OT106-tempseale B 8. LINK ITEM ID:57855 D 9. An underwater mountain chain that forms on the ocean floor is known as a A. continental shelf. B. rift zone.
There are also four outer objects which are use to serve as the gas giants. Each of outer planets such as Jupiter, Saturn, Uranus, and Neptune were encircled by planetary rings of dust and other particles. Lastly, the farthest of all is that the gray in color sphere which is said to be the Pluto. Let’s observe and look all around us! Looks like a real solar system.
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.
What did Harry Hess propose in 1963? He proposed that molten rock erupts from the Earth's interior along mid-oceanic ridges, creating new seafloor. What magnetic field, polarity evidence supports the theory of plate tectonics? -the earth's magnetic field was especially strong over the oceanic ridges that were made up of iron rich materials -the magnetic field formed a zebra-striped
It is a roughly triangular-shaped area about 250 miles on a side. On its fringes the elevation of the plateau is about 4,000 feet above sea level, and at its lowest point it is about 400 feet. The journals of Lewis and Clark briefly note the Plateau. The Columbia plateau formed between 6 million and 16 million years ago as the result of successive flows of basalt. The Columbia Plateau province is enclosed by one of the world’s largest accumulations of lava.
1. The Marianas trench is beated in the Pacific Ocean at a depth of about 11,000m below the surface of the water. The density of seawater is 1025 kg/m3. a. If an underwater vehicle were to explore such a depth, what force would the water exert in the vehicles observation window (diameter= 200cm)?
The mantle below the crust is the largest layer and is composed of denser iron and magnesium silicate rock. The high density core is predominately metal (iron and nickel) (Harold V. Thurman and Alan P. Trujillo, pg.79) In contrast, considering the physical characteristics of the Earth, how the layers respond to temperature and pressure, the Earth is composed of five layers: The lithosphere, the asthenosphere, the mesosphere, the outer core, and the inner core. The lithosphere is the outermost layer of brittle rock that fractures when pressure is applied. The asthenosphere is the plastic layer and it flows when a gradual force is applied. The mesosphere is below the asthenosphere (corresponds to the middle and lower mantle), and is rigid due to the increased pressure at depth.
ater is the chemical substance with chemical formula H2O: one molecule of water has two hydrogen atoms covalently bonded to a single oxygen atom. Water appears in nature in all three common states of matter and may take many different forms on Earth: water vapor and clouds in the sky; seawater in the oceans; icebergs in the polar oceans; glaciers and rivers in the mountains; and the liquid in aquifers in the ground. At high temperatures and pressures, such as in the interior of giant planets, it is argued that water exists as ionic water in which the molecules break down into a soup of hydrogen and oxygen ions, and at even higher pressures as superionic water in which the oxygen crystallises but the hydrogen ions float around freely within the oxygen lattice. [13] The major chemical and physical properties of water are: Water is a liquid at standard temperature and pressure. It is tasteless and odorless.
