The main systems are the steam cycle and the gas turbine cycle. The steam cycle relies on the Rankine cycle in which

Fossils are found on Mount Everest because the mountains were once the sea bed before rising. The types of fossils in Mount Everest are marine fossils. Marine fossils are sea animals‚ plants‚ or sea shells basically anything in the water that are now fossils. The types of fossils indicate the environment that these fossils were found on the ocean floor‚ meaning at one point in time‚ the seas cover the land(Geology of the Mount Everest). The marine fossils end up on Mount Everest by continental drift

were giants. Some dinosaurs were no bigger than small dogs. The smallest kind was about the size of a chicken. No human being has seen a living dinosaur but‚ scientists have many ways of learning about them. One important way is by studying fossils. Fossils give scientists a vast amount of information about ancient animal and plant life which have become extinct. They also helped them in finding out how long ago the animal or plant lived. As animals and plants die over the years they get covered

least 6 million years. A. From Ape To Man Fossils from several different early australopith species that lived between 4 million and 2 million years ago clearly show a variety of adaptations that mark the transition from ape to human. The very early period of this transition‚ prior to 4 million years ago‚ remains poorly documented in the fossil record‚ but those fossils that do exist show the most primitive combinations of ape and human features. Fossils reveal much about the physical build and activities

Uses of fossil fuel Fossil fuels consist of coal‚ petroleum and natural gas that are found under the earth’s surface‚ formed from billions of years of compression and decomposition of dead plant and animal matter. They are the leading source of energy for the mankind and are used for various purposes like energy for transportation‚ electricity‚ manufacturing process and also used in the manufacturing process of day to day items like plastic. Main fossil fuels are. 1. Coal Coal is

discussing about how were fossils found‚ techniques on finding fossils‚ and whether or not dinosaurs could have evolved to being warm blooded. Fossils are the preserved remains‚ or traces‚ of animals‚ plants‚ and other organisms left behind. Fossils are mostly found where sedimentary rocks of the right age are exposed‚ such as river valleys‚ cliffs‚ and hillsides. Paleontologists are scientists who studied fossils‚ collecting fossils from all over the world. The fossil record provides evidence

determine the age of materials. We need to understand how fossils are made so we can date them properly. There are five ways bones are fossilized. They are by permineralization‚ unaltered preservation‚ carbonization‚ authigenic preservation‚ and recrystalization (Shepherd). When a fossil is found you need to make sure that it can be preserved properly so it can stay in the same shape to enable research. Many steps are taken to prepare fossils and conserve them. Hardeners are used to protect against

E.g. A catastrophe happened to dinosaurs 80 million years ago. A comet fell on earth surface leading to volcanoes‚ leading to dust clouds in the atmosphere‚ preventing solar rays penetration ‚ the plants died and then the dinosaurs.

The false fossil left China in June 1998 and eventually turned up in a rocks and fossil shop in Tucson‚ AZ‚ where it was discovered and eventually purchased by Stephen Czerkas. Czerkas was an amaeteur fossil collector who probably didn’t know any better than to purchase pretend petrified remains. He was extremely excited and proceeded to contact an expert and call for a study of the fossil. A team from National Geographic agreed to keep details about
