All About Our Planet Earth Essay

Surprisingly, our sun isn't as big as it seems. There are many other stars that have more mass than our sun, and one example is the Rigel star. The Rigel star is a blue supergiant that is one of the brightest star found in the orion constellation. Its color is blue because it has 18 times the mass of the Sun, and is around 773 light years away from Earth/us. The Rigel star is also 117,000 times brighter than the sun. How did the Rigel star exactly form though? Well, it started as a protostar. Clouds of gas and dust mix and becomes dense, which attracts more and this begins to heat up. The cloud gets hot enough that it forms a newly born star, which lead us to the main sequence. Only 10 million years- which is young for a star, the Rigel had

“The sun is the heart of our solar system” (NASA Solar System Exploration) which is located at the center of the solar system. The sun has a radius of 432,168.6 miles. You would need 1.3 million Earths to fill up the sun. But the sun is not the largest star there are several that are much larger. The sun is the closest star to Earth which is around 93 million miles. The sun is like a big ball of gas. “In terms of the number of atoms, it is made of 91.0% hydrogen and 8.9% helium.” (NASA Solar System Exploration). But if you measure by mass the sun is made up of “70.6% hydrogen and 27.4% helium.” (NASA Solar System Exploration). Gravitational attraction which is made by pressure and temperature in the core holds together the sun. There is three main layers in the sun which are the core, the radiative zone, and the convective zone. Inside the core temperatures can reach 27 million degrees Fahrenheit

The science that is connected with planet earth encompasses geosciences or earth science among others. Containing old histories, this is considered as a part of planetary science while it possesses holistic and reductionist approaches in the science of the planet Earth. This discipline can cope with lithosphere, atmosphere, biosphere or hydrosphere. Quantitative understanding has been developed by the scientists to understand the ground systems with the tools by mathematics, physics, chronology, biology, chemistry alike that help to know how the universe is evolved.

Although all nine planets are a huge part of the solar system there's a lot more to the solar system than the nine planets. According to scientist the Solar System started out as an enormous cloud of gas and dust. Scientist believe that the cloud of dust and gas began to collapse under the weight of its own gravity and it did. The matter that was kept within itself began moving in a giant circle and at the center of the spinning cloud a tiny star began to form. The star eventually grew larger and collected more dust and gas that collapsed into it. Farther from the center of the mass that was being formed there was many smaller clumps of dust and gas that were also collapsing. The large cloud in the center eventually became the sun while the smaller clumps formed the planets, moons, comets and,

As our proto-sun was forming and spinning gases such as hydrogen and helium were pushed to outer rings of the nebula. Dust grains near the sun started to collide and overtime the particles and the collisions grew larger. Furthermore, gravity pulled these some of pieces together at a faster rate and over time this process created small planets or planetesimals . As these planetesimals grew larger they combined and created the planets closest to the sun : Mercury, Venus, Mars and Earth.

planets in our solar system came from. Does or did our star, the sun, have a

Firstly, to deduce how the Earth came to form the structures we know today in modern Earth, we must go back

NGS integrates greenhouse into other major policy initiatives, such as the Natural Heritage Trust, and launches new measures to increase greenhouse emission reduction activities across the Australian community. It provides the strategic framework for an effective greenhouse response and for meeting current and future international commitments. It will provide a fresh impetus for action by governments, stakeholder groups and the broader community and set directions for that action into the next century.

In the beginning, impacts of very large objects were very common, some as big as Mars or half the diameter of Earth. Collision of large bodies orbiting Earth played a role in its initial tilt of spin axis, the length of its day, direction of spin, and the thermal state of the interior. This violent bombardment continued for 3.9 billion years. Final composition of Earth had several crucial structural effects. Enough metal was present early on to allow formation of an iron and nickel rich core that is partially liquid. This enables a magnetic field that deflects some harmful radiation from reaching the surface. Enough radioactive elements are also present in the core to maintain long term heating which drives plate tectonics. At 4.5 billion years ago, Earth separated into different layers: an inner core (made of iron and nickel), a land layer of lower density material, and an early atmosphere of carbon dioxide and steam. At 3.9 billion years ago, surface temperatures dropped to a range where liquid water could be maintained. Liquid water makes up approximately 75% of the planet's surface today which is roughly what it was then. The most important requirement for life as we know it is the presence of liquid water. This is the one substance that can serve as a universal solvent - that is, it can dissolve and transport minerals and

Soon after the birth of earth, it was a very different place from the one we know today.

Indecent bodies like the sun. Stars are made up of big exploding balls of gas, mostly hydrogen and helium. The sun is similarly a star made up of huge amounts of hydrogen, undergoing a continuous nuclear reaction like a hydrogen bomb. Stars come about when vast clouds of hydrogen, helium and dust contract and collapse due to gravity. The clouds came from astronomical plasma from “The Big Bang”, but the dust comes from the supernovae of other stars.

H-O-M-E 4 letters with deep meaning. Home is our shelter, our family, and place where your heart is. Earth is our home, our live depend on what the earth provide and we cannot live a second without the thing that the earth provides. At the beginning, God have created the earth completely balance with its function. The forest stands as the heart of the earth because trees provide human oxygen and absorb the carbon dioxide. The earth cooled, the water vapor condensed and fell in torrential downpours at the right distance of the sun not too far and not too near. The earth perfect balance enables to conserve water. The water cut channel is like the veins of the earth body. Everything has been designed perfectly link to each other’s. We cannot imagine if the living things in the earth did not link to each other, how can a human survive. Trees cannot live without water and sun, Human

U.S. Conditions like Florida and other states with a high range of hot spells are perfect

In the United States, we consume more energy from oil than from any other energy source. In 2014 the total amount of petroleum consumed in the United States was about 19 million barrels per day. As we look into making the world a more eco friendly environment, I ask the question; what are some alternatives of oil and the effects of the alternative.
