Unit 1 - Astronomy Remediation

Master astronomy basics: solar system models, Milky Way, planet order, and universe origins!

The geocentric model was replaced by the heliocentric model of the universe. What reason would be most appropriate? The geocentric model did not predict the phases of the moon. The heliocentric model proved that the Earth rotates. The geocentric model no longer predicted the positions of the constellations. The heliocentric model provided accurate predictions of the motions of the planets. Which description would the science textbook most likely give for the location of the Milky Way? The Milky Way is the closest galaxy to our galaxy. The Milky Way is the galaxy in which our solar system is located. The Milky Way is the universe in which our galaxy is located. The Milky Way is the closest solar system, to our solar system. Fill in the blank with one of the words: circular, square, or elliptical. Comets seen from Earth follow and orbit that is very elliptical. The model represents a galaxy in the universe. The model could best be used to demonstrate which of the following? The shape of a spiral galaxy. The movement of a whirlpool galaxy. The solar system location in the Milky Way galaxy. The location of objects in an elliptical galaxy. Earth's ability to sustain life is due to which of the following? The atmosphere allows all of the Sun's radiation to enter due to Earth's distance from the Sun. The atmosphere is extremely thin due to the temperatures of the Sun. The atmosphere prevents all space debris from reaching the surface due to the ozone layer. The atmosphere is breathable due to the unique mixture of gases. Meteoroid A small particle from a comet or asteroid orbiting the Sun. Meteor A shooting star. Meteorite Lands upon the Earth's surface Asteroid A piece of rock similar to the material formed into planets. Comet Composed of dust and rock mixed with frozen water, methane, and ammonia Order from largest to smallest: Earth, Jupiter, the Moon, and the Sun. Jupiter, Earth, the Sun, the Moon the Sun, Jupiter, Earth, the Moon the Sun, Jupiter, the Moon, Earth Jupiter, the Sun, Earth, the Moon Which of the following theories predicts the origin of the universe? Heliocentric Theory Geocentric Theory Big Bang Theory Doppler Shift Theory Which diagram best presents a heliocentric model of the solar system. The symbols below represent the Milky Way galaxy, the Solar System, the Sun, and the Universe. Which arrangement of symbols is the most accurate? Write your answer choice A, B, C or D, in the blank below.
