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

LIFE ON EARTH REVISION Analysis of the oldest sedimentary rocks provides evidence for the origin of life. - Identify the relationship between the conditions on early Earth and the origin of organic molecules. - Formation of the organic molecule was the first event in the evolution of life. - The molecules provided a building block for cell formation and the food for the earliest life. - Present day life’s atmosphere contains: - Oxygen - Water - Carbon

spaces in between rock and sediment in liquid form. Natural gas is also formed from the remains of microorganisms but is in the gaseous form. Natural gas mostly is made up of methane (CH4) and is highly compressed in small volumes deep within the earth. Coal is highly abundant compared to oil and natural gas. Some analysts predict that the use of coal will increase as oil supplies decline. The coal supplies that we have now could last up to 200 years or longer. Undeveloped countries can not afford

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

documented. With the retreating of these glaciers is the depletion of the freshwater supply. The author rebuts the statements of those who believe climate change is natural by saying that the climate is warmer than other warm phase the Earth has been through. The reason the Earth is going through this period of abnormal warmth is due to the climate not having been exposed to the greenhouse gases previously. He states that the amount of heat that the sun provides has been decreasing since 1940 and that the

“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

EARTH AFTER A 5000 YEARS!!!! If you could travel back in time five centuries‚ you’d encounter a thriving Aztec empire in Central Mexico‚ a freshly painted "Mona Lisa" in Renaissance Europe and cooler temperatures across the Northern Hemisphere. This was a world in the midst of the Little Ice Age (A.D. 1300 to 1850) and a period of vast European exploration now known as the Age of Discovery. But what if we could look 500 years into the future and glimpse the Earth of the 26th

The Earth on Turtle’s Back The story I chose to write about is The Earth on Turtle’s back. I chose this selection because it’s based upon a mythical story which has been around for decades. After reading this story‚ I came to a conclusion about the Native Americans. The Native Americans had high hopes and valid respect for nature and their natural environment.
