This theory states that the Moon was once part of the Earth, but somehow separated from it. This is believed to have happened in early history times of the solar system. It is believed that the Moon most likely broke off of the Pacific Ocean basin. This is because the Moon 's composition is the same as the Earth 's. The Moon has a core, which is much smaller than Earth 's, that is made of mostly iron and nickel.
Rare earth metals are a group of 17 that are found together on the periodic table. The whole rare earth metals are made only of metals. the group consists of yttrium and the 15 lanthanide elements. The first element in row 6 is lanthanum which is where the lanthanide group got its name. The word "rare” can make you think that the world is lacking these elements but the elements are in fact relatively abundant in the Earth's crust but in limited, insufficient amounts.
(Cowen, 1998) Volcanoes. Mars is home to the largest volcano in the solar system, Olympus Mons. Olympus Mons is extinct and stands 16 miles (25 kilometers) and has a caldera that is 50 miles (80 kilometers) wide. Nearby are three smaller volcanoes that are also extinct. These volcanoes are near the canyon, Valles Marineris.
Nickel as a mineral does not normally occur in water systems. The water effluents from the steel and allied alloys, electro platting, paints, ceramics and food industry are largely the source of this contamination. Nickel is used in metallurgy of alloys, magnets, protective coating, catalysts, and batteries. The toxicity of nickel to aquatic life varies widely and is influenced by nickel compounds, pH, synergetic effects, and other factors. The average abundance of Ni in the earth’s crust is 1.2 ppm; in soils it is 2.5 ppm; in streams it is 1μg/L, and in groundwater it is <0.1 mg/L.
The Chicxulub impact, known as the Chicxulub crater, was formed by an asteroid that collided with the Yucatan Peninsula located in Mexico 65.5 million years ago. The asteroid was said to hold the same energy as 100 million atomic bombs which precipitated an incident that destroyed the dinosaurs and nearly all life on Earth, leaving the atmosphere inhabitable for centuries. What is an Asteroid? Asteroids are pieces of rocks that aren't called planets based on the how small they are. The asteroids are orbiting around the sun mainly in what we call the asteroid belt - an area between the orbit of Mars and Jupiter.
Full Article About The Moon 19: File Under: articles, astronomy, Moon - BULAN 1- The Moon is the only natural satellite of the Earth, and is the largest natural satellites in the solar system. The moon does not have its own source of light and moon light actually comes from the reflected light of the Sun. - ORBIT - The Moon around the Earth -- BULAN 2 The full moon - -- BULAN 3 Half moon full moon - - BULAN 4 The pocked surface of the Moon - - BULAN 5 Craters on the Moon - - The average distance earth-moon from the Center to the Center is 384,403 km, about thirty times the diameter of Earth. The diameter of the Moon is 3474 km, slightly smaller than a quarter the diameter of the Earth. This means the volume of the Moon is only about 2 percent of the volume of the Earth's gravitational pull and on its surface about 17 percent than the pull of gravity upon Earth.
The first time the pea soup or the homogenate was centrifuged, the starch granules got separated and remained at the bottom in sediment I. The speed for this differential centrifugation was set at 1300 RPM; which is lower than the second centrifugation’s speed (Halaby et al 2011). Thus, the heaviest and densest organelles got isolated first. This indicates that starch granules are the heaviest organelles because they were isolated first. The second differential centrifugation was done to isolate the organelles found in Supernatant I which were the nucleus, chloroplasts and mitochondria.
Up to this date the approximated percentage of the ocean area that is discovered is only 5% (NOAA 1). The sheer percentage of the unexplored is a simple deterrent from space exploration, without the full understanding of what exists terrestrially the understanding of anything extraterrestrial should be of no priority until the Earth is understood. The rock beneath the Earth is another unknown as shown by the fact that the deepest borehole is only 8 miles deep
(Review on)STUDY OF THE WATER QUALITY CONTAMINATED by SUGAR with distillery MILL EFFLUENT INTRODUCTION The total amount of global water, only 2.4% is distributed on the main land, of which only a small portion can be utilized as freshwater. The available freshwater to man is hardly 0.3-0.5% of the total water available on the earth and, therefore, its judicious use is imperative (Hegade & Kale 1995). It is believed that ground water must possess degree of purity, free from chemical contamination and micro-organisms. But the rapid increase in population and industrialization together with the lack of wisdom to live in harmony with nature has led to the deterioration of good quality of water 2; thus, resulting water pollution. Ground water as
DUET Karachi Date: 18-10-2016 Purpose and Introduction: Water is the most essential and most important thing in the earth. Every human being and every living organism need water. 80% of human body’s made by water. Water is crucial element of our food and materials. 75% of earth’s surface is covered with water, and only 3% is clean water and only 1% of the water is available for human consumption.
