The layers of Earth How do scientists know what is in the center of the earth? How can we know what the core of the earth is made of‚ if scientists have never studied any materials from a depth below 7.5 miles? Earth is approximately 4.6 billion years old‚ and over this time period‚ many things have changed inside and out. The formation of our planet is quite amazing. Earth consists of multiple layers. The three most distinct or main layers are the core‚ mantle and crust. The inner portion is

ES 1010‚ Unit 8 Question 11 - Discuss stellar evolution (describing each stage in brief). What forces are opposing one another throughout the life of a star and how do they influence the various stages in the life cycle of a star Stellar evolution stars exist because of gravity. The two opposing forces in a star are gravity (contracts) and thermal nuclear energy (expands). Stage 1 Birth is where gravity contracts the cloud and the temperature rises‚ becoming a protostar. Protostars are a

church‚ the age of the earth was 6‚000 years old. 2. James Hutton discovered that the earth was much older from the tilted rocks because he knew these rocks was once laid down horizontally on the sea floor and were buried under great depth to be crystalized. Then they were tilted on end by great earth forces and then eroded away. The rocks were then deposited on top. He understood it had to take millions of years for this process to happen. 3. Lord Kelvin calculated the earth to be around 20 million

The major theme that is in this documentary is self explanatory which is arguing that the earth is flat. This documentary and our class in my point of view both have a smilier theme. A simple answer is that they both discuss myths. For example in the documentary‚ Mark discusses that the Earth is flat and tries providing many points of proof and in class we had earlier talked about the Lion Gate in Argolid‚ Greece. According to Greek mythology‚ the Lion Gate was built by cyclops because physically

“How the Earth was Formed” video notes: Theory: -sun was surrounded by a cloud of dust and gas -as cloud cooled little grains of minerals started forming -grains of minerals started bumping into each other (Problem was nobody could explain how these microscopic minerals formed a planet) Then in 2003 astronaut Don Pettit performed an experiment onboard the international space station. He put some salt in a plastic bag and found that almost immediately the grains started gathering together into little
