10. They have very high redshifts and they can change their brightness quickly which indicates that they are very small. 15. The spectral lines are shifted out of the visible spectrum because they are very tiny. Chapter
The circumference came out to be 7.66 which was too extremely off of my previous findings. I feel that this moon has this ability for small amounts of change because of horizon landscapes and objects. Where you take these observations will add variety to numbers too if you aren’t located in the same location. This lead to my hypothesis having some basis behind it because the illusion has to do with the earth and its landscape providing the illusion. The illusion is based off of the moon’s size and the objects and landscapes connected with it.
(a) (b) (c) 8. Provide an example of developments in geography for each of the following: [pic] 9. Define scale: 10. When geographers convert the round earth to a flat map, they use a projection. All projections have some distortion (only a globe has none).
His observations of planetary motion, mostly that of Mars, gave important data for astronomers to come, like Kepler. This helped us construct our model of the solar system we use today. The calculation that if the Earth moves then the stars are at least 700
It is, therefore, true to say that everything that exists in the Universe is not permanent. The importance of the Sun to life on Earth 1. Earth and other planets are linked to the Sun by a gravitational force. The gravitational force of the Sun is always present to keep Earth in the right position to receive light and heat from the Sun. 2.
Sunspots can be quite small ([IMAGE]1500 km diameter), and reach sizes up to 50000 km. While it is known that the darker appearance of the umbra and penumbra is due to their lower temperatures, the sharpness of the boundaries between the umbra and penumbra, and between the penumbra and photosphere, is a phenomenon that is not yet properly understood. While sunspots, especially large ones, can be fairly long-lived (their lifetimes being measured in weeks and months), they do eventually disappear, often by successive fragmentation into smaller and smaller sunspots. Likewise, sunspots do not suddenly appear fully grown, but usually show up as small structures, irregularly shaped and usually without a penumbra (darker structures without penumbra are
Name: Date: Period: 1. are natural or artificial bodies that revolve around more massive bodies such as planets. (Satellites or Comets) 2. Most lunar craters are the result of . (volcanoes or impacts) 3. The time it takes for Earth to around the sun is 1 year.
(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
Large desert areas strewn with mysterious globules of "glass"—known as tektites--are occasionally discussed in geological literature. These blobs of "hardened glass" (glass is a liquid, in fact) are thought to come from meteorite impacts in most instances, but the evidence shows that in many cases there is no impact crater. Another explanation is that tektites have a terrestrial explanation-- one that includes atomic war or high-tech weapons capable of melting sand. The tektite debate was summed up in an article entitled "The Tektite Problem", by John O'Keefe, published in the August 1978 edition of Scientific American. Said O'Keefe: If tektites are terrestrial, it means that some process exists by which soil or common rocks can be converted in an instant into homogeneous, water-free, bubble-free glass and be propelled thousands of miles above the atmosphere.
