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.
D. Scholar Geography 1 November 11, 2012 Test Corrections #1 Question: Which atmospheric heating process involves the emission of energy from an object? Correct Answer: E) Radiation My Answer: D) Why it’s Wrong: Radiation is the right answer because it has much stronger. It’s stronger than transmission, scattering, reflection and absorption. A good example would be: if your wearing a black shirt out in the sun you would be much hotter than if you’re wearing a white shirt. The black shirt would also fade over time because the suns rays would eat up the shirt.
When comparing a star's brightness from Earth, it will always appear dimmer than the Sun. This is due in large part to Earth's close proximity to the Sun. Comparing the sun's brightness to Capella's from Earth is unfair because Capella is actually made up of four separate stars. The two yellow giants that make up Capella are quite similar to the Sun. All three stars are yellow giants and give off a similar color of light.
12. How does the fact that the Earth has a magnetic field help provide evidence for the theory of plate tectonics? The magnetic “structure” of the Earth is changing because of plate tectonics. 13. What were the main components of the atmosphere when the Earth formed, and what are the main components today?
If the orbit is indeed highly elliptical, then the temperature variance range will be extreme. Scientists can estimate the possible surface conditions as
Depending on the current temperature on the stove the only way that you would be able to make the stove burn hotter would be to raise the amount of voltage. This means that the voltage would have to be multiplied to make the stove have a larger resistance thus making the heat higher. 7. The Hubble Space Telescope can see stars and galaxies where brightness is 1/50 of the faintest objects now observable using ground-based telescopes. Use the fact that the brightness of a point source, such as a star, varies inversely as the square of its distance from an observer to show that the space telescope can see about seven times farther than a ground-based telescope.
The dates observed on the simulation set up are very much different from the dates given in the astrological calendar for the entry and exits of the sun. According to the astrological calendar the sun passes through 12 constellations whereas according to my observation on the starry night set up the sun passes through 13 different constellations. The constellations are of different size and since the ecliptic passes through larger or smaller portions of each constellation and the speed of the Earth around the Sun vary along its orbit. Therefore, the time period that sun remains in each constellation vary. I think these dates are different because the astrologers predict that the size of constellation different than what astronomers consider the size of constellation.
This happens when the normal winds weaken which allows the warm water that is usually found in the western Pacific change direction and instead move towards the east. This warm water replaces the cold water which is normally found near the surface of the eastern Pacific. All these occurrences are what affects a lot of weather patterns in many parts of the
(1) The orbit of each planet is an ellipse with the Sun at one focus. (2) As a planet moves around its orbit, it sweeps out equal areas in equal times. (3) More distant planets orbit the Sun at slower average speeds, obeying the mathematical relationship p2 = a3. h. How does the Earth rotate and how does that relate to day and night or the seasons? The Earth rotates on its axis and orbits the Sun.
Physical size = angular size x 2 x distance / 360 • Understand that constellations are groups of stars as seen from the Earth – the stars may not be close to each other at all • Our view of the celestial sphere is determined by where we stand on the Earth o Study the diagrams that show the path of stars as they rise and set and how those paths appear to differ depending on your location on the Earth • Know what causes the seasons (tilt of the Earth’s axis to it’s orbital plane) o Depend on how Earth’s axis affects the directness of sunlight o Sun’s altitude is also higher in Summer and Lower in Winter Summer solstice – highest path Winter solstice – lowest path Equinoxes – sun rises at exactly due east and sets exactly due west • Review the Moon’s phases • New Moon • Waxing (Right side of moon visible) o Waxing
