With a little bit of carbon, nitrogen and oxygen about 1.5%. The other 0.5% is made up of small amounts of a lot of other elements such as neon, iron, silicon, magnesium and sulfur. The definition of Mantle is the planet between the core that is the mantle. There is the upper Mantle and lower Mantle. Did you know that Uranus and Venus spin the opposite direction? Venus spins the opposite direction because it’s axial is tilt at 177 degrees which means that means it is almost spinning the opposite direction to the orbit. Uranus axial is at 97.77 degrees so the axis parallel to the plane of the Solar System. Our Solar System is ginormous, Scientist discovered that the solar System is 40 astronomical units. One astronomical unit is 9.296e+7
One of Texas’ most famous natural landmark is a giant pink rock. Enchanted Rock in Fredericksburg is a massive pink granite dome that is 1,825 feet above sea level at the summit, and the entire dome covers 640 acres.
in circumference. The outer few miles of lithosphere is made up of rock called crust.

In Lester R. Brown's novel Full Planet, Empty Plates, the issue of food scarcity is explained through an environmental perspective. He begins the novel by addressing the issue of the world's high demand for crops, such as grain, and the stress it places on farmers to keep up with the increase in demand. In a time where there is a significant water shortage, higher temperatures, and eroding soils, food scarcity should be at the top of everyone's agenda. Brown poses the question whether or not food scarcity will be our civilization's "weak link" in terms of survival. He demonstrates how food security is a serious issue across the globe. As supply decreases, demand increases, thus raising the price of food. Unlike global resources such as oil,
A Miracle Mineral Solution is being attempted to be sold by an online ‘church’ as a cure-all for many of the world’s diseases, such as cancer, autism, and HIV/AIDS. The Miracle Mineral Solution is a diluted bleach mixture that is being prompted and sold in Canada, regardless of all the Health Canada warnings. Health Canada is saying that MMS is unsafe for human consumption because it contains sodium chlorite, which poses serious health risks if ingested. MMS is usually taken orally or through enemas. In some cases the mixture is being used by parents who are looking for a cure for their children that have autism. The founder of the online ‘church’, Jim Humble claims that “up to 95 per cent of all diseases caused by pathogens can be cured with
Mercury is in many ways similar to the Moon: its surface is heavily cratered and very old; it has no plate tectonics. On the other hand, Mercury is much denser than the Moon (5.43 gm/cm3 vs 3.34). Mercury is the second densest major body in the solar system, after Earth. Actually Earth's density is due in part to gravitational compression; if not for this, Mercury would be denser than Earth. Mercury has a total area of 75 000 000 square kilometers and is the closest planet to the sun in the solor system. This indicates that Mercury's dense iron core is relatively larger than Earth's, probably comprising the majority of the planet. Mercury therefore has only a relatively thin silicate mantle and crust.
What is religion? To some “it is the belief and the worships of a superhuman controlling power, especially a God or gods. The Jewish religion and the Muslim religion are two of the most important religions in our society today. Each of the important religions of today began during trying times in the world. Not unlike the other religions, the Jewish religion and the Muslim religion and its followers have had their struggles from its beginning. One of the struggles of these two has to do with politics and a struggle for power. For the Jews and Muslims this struggle and strife began in their homeland of Jerusalem. This struggle for political
In chapter seven we learned about the electron structure of an atom. We learned about the Bohr model, electromagnetic energy, and many other related topics. In this essay I will explain in further detail what light really is and how we describe it. I will describe the behavior of electrons in both a hydrogen atom and all atoms. I will explain the arrangement of the elements in the periodic table, state which electrons are chemically important in atoms, and lastly I will describe the properties of atoms and their relation to their electron arrangements. The information provided will be my interpretation of the chapter, and my outlook on what this chapter was about.
The time between the formation of the earth and the beginning of the Cambrian(about 570mya) is a 4000 my long period known as the Precambrian, this includes approximately 90% of geological time of which we know very little about as pre-Cambrian rocks are poorly exposed, many have been eroded or metamorphosed and fossils are seldom found.
Pluto: A Planet of the Earth? Many issues have arisen from the debate over whether or not Pluto is a planet. Some astronomers say that Pluto should be classified as a “minor planet” due to its size, physical characteristics, and other factors. On the other hand, some astronomers defend Pluto’s planet status, citing several key features. Indeed, most of the problem is that there is no formal definition of a planet.
Core/Interior: The Earth has three layers to it's interior, the inner core, outer core, and mantle. Of these the outer core is thought to be liquid. Like most of the terrestrial planets at birth, the Earth has been molten and undergone some differentiation allowing the heavy material which is consisting mostly of an iron, nickel, and cobalt core making it's density five and a half times the density of water.
The Periodic Table is based around the Atomic Theory. Firstly people believed that everything was made up the four elements Earth, Fire, Wind, and Water. This theory evolved into everything being made up of atoms. Breakthroughs throughout history such as the discoveries of the nucleus, protons, neutrons and electrons have pushed this theory forward to where it is today.
Our solar system has eight planets, their moons and satellites, and they are all orbiting the Sun. The eight planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Pluto used to be the ninth planet but IAU changed the definition of planet and Pluto did not meet the standards so it is now a Dwarf planet.
Earth system refers to the earths interacting physical, biological, and chemical processes. The system consists of land, oceans, atmosphere and poles. The earth system has four spheres, including the geosphere, the hydrosphere, the atmosphere, and the biosphere. The geosphere refers to the solid parts of the earth system, including earth’s rocky crust, mantle, and the metallic core. Within the geosphere is the lithosphere, which only refers to the uppermost layers of solid earth. The uppermost layers of solid earth are the oceanic and continental crust rocks. Just below the crust is the mantle, which is composed mostly of magnesium and iron silicate minerals. The mantle accounts for about 2/3 of the
The lithosphere is an open system, which contains all of the cold, hard, solid rock of the planet's crust (surface), the hot semi-solid rock that lies underneath the crust, the hot liquid rock near the center of the planet, and the solid iron core (center) of the planet (Answers.com). On Earth, the lithosphere comprises the crust and the upper part of the mantle. The lithosphere is about sixty miles thick (Lenkeit).
