Meteorite

An impact basin or impact crater is defined as the circular depression in the surface of a solid body in the solar system such as moon or some other planet. A lunar impact basin is a depression / cavity caused by a meteor or comet hitting the Moon with a greater speed. Impact basins typically have raised rims and floors that are lower in elevation than the surrounding surface. There are over 40 impact basins on the Moon. These basins were created by extremely powerful impacts, which usually…

After the discovery of hydrothermal vents, an alternative theory about origins of life have arisen, from new evidence found from these vents, that early life could have begun from hydrothermal vents. It has been theorised that the first organisms on earth had been autotrophs and were able to synthesise organic compounds from inorganic material in the surrounding environment (Morowitz et al. 2000). In the ecosystems surrounding these hydrothermal vents, the organisms living within these…

One of the most important physical properties of molecules is their chirality, or lack thereof which is known as achirality. Chirality is defined as the ability of a molecule to exist in two no superimposable images called enantiomers. This means that achirality is the opposite, in which molecule is superimposable on its mirror image. When two molecules are related in the fact that they are stereoisomers of each other, but are not mirror images. In nature chiral molecules do not exist in their…

a major meteorite impact may not have been the sole cause of the mass extinction involving the dinosaurs 66 million years ago. Researchers have discovered an array of huge volcanic eruptions in india 66 million years ago which released large amounts of gases into the atmosphere, which drastically altered the climate. This new theory does not in fact eliminate the theory of a massive meteorite being a leading cause for the extinction of the dinosaurs, it simply examines how the meteorite is…

impact of an asteroid crashing onto the Earth’s surface can create insanely high temperature and pressure needed to create the diamond. Diamonds have actually been found near some impact sights. Scientists have also discovered diamonds inside of meteorites that have crashed into…

where 90%of earth's history was discovered. Life first started evolving, and progresses and changed the planet. Scientists discovered the truth about organic compounds, the first prokaryotic cells and the first meteorites to hit the earth. Scientists believe that some of these meteorites gave rise to organic compounds, or life's building blocks. The Cambrian Period lasted from 541 to 485 million years ago. Scientist discovered here that the first signs showed up in water. This led to the…

Meanwhile (Haryatmoko:2014:45) states that, Black campaign is a weapon of destruction of a successful team and a political consultant. In general, form of black campaign is spreading ugliness a politician with the aim of overthrowing the reputation of a politician that he became unpopular with his supporters and the general public audiences. He states that, the negative sentiment will trigger resentment towards certain groups. If black campaign is allowed to continue without control, would…

the most distribution, except for humans, but what happened to them? Where did they go? Hundreds of wolves died because people thought they were dangerous, so when they saw them they sadly shot them. It’s actually there’s a better chance that a meteorite would hit you than a wolf killing you! Adult male wolf’s average 95-100 pounds, while adult female average 80-85 pounds. A male body length averages from 5-6 1/2 feet from nose to tail tip, and average of 4 1/2- 6 feet. Most have a…

The Solar System By Krishiv There is always something that you are pondering about. From the periodic table to the circulatory system. But did you know that the majority of people wonder about the Solar System? It is the final frontier, or the one thing that is not fully discovered. There are many unique masses in the Solar System. They range from planets like the earth to rocks such as asteroids, comets, and meteors. But one thing is for certain… every mass has to orbit the sun.…

Rogue Waves and Tsunamis: What are rogue waves and tsunamis? Rogue waves are stealthy waves that come out of nowhere. Tsunamis are caused by tectonic plates full of pent-up energy that cause the plates to shift, moving water in the process. Rogue waves and tsunamis have some similarities, but also many differences. Rogue waves stand out and have multiple causes. Rogue waves have a unique appearance. The text, “What are Rogue Waves?”, states “...as high as 100 feet...”(Simmons 58). Rogue waves…
