Which of the following best explains the success of the central African rainfall-prediction technique of observing the waxing crescent Moon? A) When the Moon is aligned in a U-shape, it can hold more water, so there is more rain. When it is tilted, it can hold less, so the weather is drier.

Which of the following persons developed a system for predicting planetary positions that remained in use for some 1500 years?
Why did Ptolemy have the planets orbiting Earth on “circles upon circles” in his model of the universe? He developed a system for predicting planetary positions that remained in use for some 1,500 years. He discovered that the orbits of planets are ellipses.
When Copernicus first created his Sun-centered model of the universe it did not lead to substantially better predictions of planetary positions than the Ptolemaic model?
When Copernicus first created his Sun-centered model of the universe, it did not lead to substantially better predictions of planetary positions than the Ptolemaic model. Why not? Copernicus used perfect circles for the orbits of the planets.
What is the meaning of Kepler’s third law p2 a3 quizlet?
Kepler’s third law states that for any planet orbiting the Sun, the orbital period squared (p2 ) is equal to the average orbital distance cubed (a3) , or p2=a3 . ... Earth travels faster in its orbit around the Sun in January than in July.
Which of these four ellipses has the greatest eccentricity?
Eccentricity describes the amount by which an ellipse is stretched out compared to a perfect circle. Because Ellipse 4 is the most stretched out of the four ellipses shown, it has the greatest eccentricity.
Which of the following were key pieces of evidence that led to widespread acceptance of the Sun centered model?
Which of the following were key pieces of evidence that led to widespread acceptance of the Sun-centered model “extraordinary claim” during the period from about 1609 to 1630? – Galileo’s telescopic observations . – The fact that Kepler’s laws allowed virtually perfect prediction of planetary positions.
What did Kepler prove?
Using the precise data that Tycho had collected, Kepler discovered that the orbit of Mars was an ellipse . In 1609 he published Astronomia Nova, delineating his discoveries, which are now called Kepler’s first two laws of planetary motion.
Who proposed the geocentric view that was accepted and used for more than 18 centuries?
The most highly developed geocentric model was that of Ptolemy of Alexandria (2nd century ce). It was generally accepted until the 16th century, after which it was superseded by heliocentric models such as that of Nicolaus Copernicus. Compare heliocentrism; Ptolemaic system; Tychonic system.
Did ancient people detect stellar parallax?
B) Stellar parallax was first observed by ancient Greek astronomers .
Why was Aristarchus’s model not accepted?
Why was Aristarchus’s model not accepted? ... Aristarchus was not as famous as Aristotle. Aristarchus could not answer some important questions about the model . Choose the correct answer to complete the paragraph about the acceptance of the heliocentric model.
Who was Brahe’s most famous student?
Brahe’s Most Famous Student
Brahe was a nobleman, and Kepler was from a family who barely had enough money to eat. Brahe was friends with a king; Kepler’s mother was tried for witchcraft, and his aunt was actually burned at the stake as a witch.
Why was the Copernican model not accepted?
| Planet | Venus | 0.723 | 0.615 | 0.999 |
|---|
What is the meaning of Kepler’s third law P2 a3?
If the size of the orbit (a) is expressed in astronomical units (1 AU equals the average distance between the Earth and Sun) and the period (P) is measured in years, then Kepler’s Third Law says P2 = a3. ... Q: The Earth orbits the Sun at a distance of 1AU with a period of 1 year.
In which direction on the horizon does a crescent moon rise quizlet?
As we watch the sky in daytime and nighttime, we see the Sun, Moon, and stars on the horizon rise in the East and track through the sky to set in the West.
What does Kepler’s third law state?
Kepler’s Third Law: the squares of the orbital periods of the planets are directly proportional to the cubes of the semi major axes of their orbits. Kepler’s Third Law implies that the period for a planet to orbit the Sun increases rapidly with the radius of its orbit .
