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

My Reflection: Honestly I’m not really good in Science. But I’m striving hard to get along with this subject and the same as Math. This subject is one of my weaknesses among all subjects. But now I can get along with this Science subject and luckily I become a lover of this. For me‚ the subject teacher really matters on how I want a certain subject. I really love when it’s Science time and I really enjoy this subject and maybe when you will take a time to open my notebooks‚ my Science notebook

She sets up an experiment with a light bulb to represent the sun‚ a large beach ball to represent Earth‚ and a smaller foam ball to represent the moon. She researches the position of the sun‚ Earth‚ and moon at different times of a month and makes a model of the entire system. 1. Identify the parts of the scientific method in

Aphelion: (opposite of perihelion) the point in its orbit where a planet is farthest from the Sun; when referring to objects orbiting the Earth the term apogee is used; the term apoapsis is used for orbits around other bodies. 2. Astronomical unit – (1 AU = 149‚597‚870.691 kilometers) An Astronomical Unit is approximately the mean distance between the Earth and the Sun. It is a derived constant and used to indicate distances within the solar system. Its formal definition is the radius of an

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

Weather and Atmospheric Water Humidity- the amount of water in the air in a particular spot. Relative Humidity- the percentage of water vapor a certain volume of air is holding relative to the max amt it can contain. 80% humidity means that it is holding 80% of the total amt of water that it can hold at that temp. Heat Index- shows what the temperature feels like due to humidity. Dew Point- the point at which air becomes saturated with water. Water will condense from the air as dew‚ if the
