Venus essays

Venus essays Venus is one of the brightest objects in the sky, so it is clearly visible to the naked eye. It can be tricky to see because it is always near the Sun. So it rises and sets with the Sun each day. Venus rotates "backwards," so the Sun rises in the west and sets in the east. Ancient civilizations believed they were actually two different objects, so they called the one, which rose the Morning Star, and the one, which sets the Evening Star. Astronomers figured out that it was one object. Venus formed about 4 Billion years ago. At the conclusion of forming, it continued to be hit with leftover material. Venus warmed from the inside and separated into layers. Since Venus is so close to the sun, the atmosphere formed differently than Earths. Venus is known as earths sister planet. In some ways they are very similar. Venus is a little smaller than Earth (95% of Earths diameter and 80% Earths mass). Both have few craters indicating young surfaces. From the similarities, it was thought that below its dense clouds, Venus might be very earth like and might even have life. However, with more detailed study, Venus is different than Earth in many ways. Venus has a slow rotational period, single plate surface, lack of a satellite, extremely weak magnetic field, lack of water, high surface temperature, and dense atmosphere. These are the differences but we still have a lot to learn about our Sister Planet. The interior of Venus is probably similar to Earths interior. Venus, like Earth, is one of the terrestrial planets and is made of rock and metal. It probably has a partly molten metallic core, a rocky mantle, and a crust. The surface of Venus consists of 2 large continents which are Ishtar Terra, found near the north pole of Venus and Aphrodite Terra, found near the equator of Venus. It has mountain ranges, and a few large islands. There are craters that show, liquid once f ...

Charles Goodyear - The History of Vulcanized Rubber

Charles Goodyear - The History of Vulcanized Rubber Caoutchouc was the name for rubber used by the Indians of Central and South America. History of Caoutchouc Besides pencil erasers, rubber was used for many other products, however, the products were not standing up to extreme temperatures, becoming brittle in winter. During the 1830s, many inventors tried to develop a rubber product that could last year-round. Charles Goodyear was one of those inventors, whose experiments put Goodyear into debt and involved in several patent lawsuits. Charles Goodyear In 1843, Charles Goodyear discovered that if you removed the sulfur from rubber then heated it, it would retain its elasticity. This process called vulcanization made rubber waterproof and winter-proof and opened the door for an enormous market for rubber goods. Rubber Bands - On March 17, 1845, the first rubber band was patented by Stephen Perry of London, made from vulcanized rubber.
