Phenomena on the Sun’s surface | 1. Prominences, solar flares and sunspots are examples of phenomena that occur on the surface of the sun. 2. These phenomena are believed to occur because of the changes in the magnetic field of the sun. Prominences 1.
The is a region of the sun where hot and cooler gases circulate in convection currents. a. chromoshpere b. photosphere c. corona d. convective zone 11. The motion of a planet traveling around the sun is called a. an orbit b. a revolution c. a rotation d. circling 12. The path that a planet takes while traveling around the sun is called a. an orbit b. a revolution c. a rotation d. circling 13. The spinning of a planet on its axis is called a. an orbit b. a revolution c. a rotation d. circling 14.
Chapter 1 • Review the components of our solar system – sun, planets, moons, asteroids, comets and their definitions o Star – a large, glowing ball of gas that generates heat and light through nuclear fusion o Planet – a moderately large object that orbits a star; it shines by reflected light. Planets may be rocky, icy, or gaseous in composition o Moon (Satellite) – an object that orbits a planet o Asteroid – a relatively small and rocky object that orbits a star o Comet – a relatively small and icy object that orbits a star o Solar System – a star and all the material that orbits it, including its planets and their moons o Nebula – an interstellar cloud of gas and/or dust o Galaxy – a great island of stars in space, all held together
Comet tails are made up of simple ionized molecules, including carbon monoxide and dioxide. By action of solar wind, molecules are blown away, forming a thin stream of hot gases continuously ejected from the solar corona. In case you do not know the meaning of a solar corona, it is the outermost atmosphere of the Sun. Amazingly, the thin streams of high gases move at a speed of approximately 400 kilometers (250 miles) per second (as cited in Yeomans 1991 p. 185). In addition, a comet frequently also displays smaller, curved tails composed of fine dust particles blown from the coma by the pressure of solar
Describe two ways in which gravity has a part in the life-cycle of a star- Gravity pulls the dust and gas in the nubula together, and compresses them so much that the inside becomes hot enough for fusion reactions to start. Gravity also pulls the remains of a red giant together after fusion reactions have stops. This forms a white dwarf. Theories about the universe- 1. What does red shift tell s about distant galaxies?
They changed because the molecules of hydrogen and helium were moving so fast that they eventually escaped the Earth. 14. Explain how the greenhouse effect works and how it relates to global warming. The greenhouse effect is when radiation at visible wavelengths passes freely through the atmosphere and is absorbed at the ground. The ground heats up and emits infrared radiation.
The idea could be considered as madness but others may say THIS IS PHYICS! ￼ After the giant nebula has started to converge it forms a Protostar, this Protostar is halfway between a nebula and a star. Eventually it gets to a point where it cant contract any more gas and the tremendous pressure starts to cause tremendous hear, and thus nuclear fusion begins, true story. ￼
(2 points) Mars. B) Cosmic Origin of the Element CLUE: The substance collected has properties indicating that it contains a few different elements. The elements in your sample were formed in a supernova and released into space when the star exploded. Small stars and cosmic rays are not hot enough to form them. Look at the chart below to see which elements are typically formed in supernova and which ones are not.
