D) All asteroids lie in the asteroid belt between Mars and Jupiter. Why was the Shoemaker-Levy 9 impact so important to astronomers? c) The inner planets orbit the Sun counterclockwise while the outer planets orbit the Sun clockwise. Comets are usually made up of ice dust and gas meaning that options A and D are wrong. In the asteroid impact theory of the extinction of the dinosaurs some 65 million years ago, the dinosaurs (and over half of all the other species on Earth at that time) died off largely because. Explain. Comets generally have elongated elliptical orbits. The dust and gases contribute to forming a tail that stretches millions of kilometers from the Sun. surface of layer, Q:In which of the following transformations undergone by (B) In adiabatic process, change in. (C) They are formed before the coma expands. 2 Some scientists think asteroids formed much closer to the Sun where it was too warm for any. Biosphere. a)All the planets except Uranus orbit the Sun counterclockwise; Uranus orbits in the opposite direction. A rocky leftover planetesimal orbiting the Sun is, An icy leftover planetesimal orbiting the Sun is. B. Comets glow by their own light. The birthplace of comets is a cloud of icy dusty aggregates beyond the solar system. a) Asteroids and comets are much smaller than planets. What part of a comet points most directly away from the Sun? 2. This answer has been confirmed as correct and helpful. Comets are small celestial bodies of the solar system that are usually made up of icy volatile gases, icy water and dust particles. C. Comets are mostly made up of dust particles, frozen water and frozen gases. $$ Which of the following statements is not true? The iron-rich asteroids, especially, should contain a high proportion of heavy elements that sank to Earth's core and are therefore very rare on Earth's surface (and consequently expensive). Briefly describe the evidence suggesting that a 10-km asteroid or comet hit Earth at the time of the dinosaur extinction. C) Most of the trillions of comets in our solar system have tails. Why do astronomers conclude that asteroids were never part of a full-sized planet? CA nationwide astro-photo competition will be organized in March, 1997. Earth, other planets, and the rest of the solar system formed billions of years ago from elements created in previously existing stars. Which of the following is not a major pattern of motion in the solar system? They have irregular shapes and varied sizes. Q:If a ball is thrown straight up into the air, what is its acceleration as it reaches its highest, A:If a ball is thrown straight up into the air and as soon as ball reaches its highest point the, Q:The nucleus of8Be, which consists of 4 protons and 4 neutrons, is very unstable and spontaneously, Q:Suppose you have a circuit in which you have connected 3 batteries, each of which that has voltage, A:Given data, How much negative electric charge is, A:GIVEN;- What is the difference between a meteoroid and an asteroid? what things would u need to survive the tropshere?. n=3, Q:Air is pushed steadily through a forced-air furnace pipe at a steady speed of 4.0 m/s.

Q:why is mechanical energy not conserved in the collision of the projectile with a pendulum? c. Comets may go around the Sun in any direction. A comet that has an orbit around the Sun inclined to the ecliptic plane by 65 probably originated in the Kuiper belt. A Some comets are believed to have originated in a region near the edge of the orbit of the outer planets in our solar system called the scattered disk that overlaps a region called the Kuiper belt. Why?, all water found on earth cannot be used for drinking why ? (3) From the previous two ideas, Earth would not have been as heavily impacted. Explain how observations of asteroids, comets, and meteorites test our theory for the formation of the solar system in unique ways that are not possible through observations of the planets. A:Write the expression for the magnetic field intensity. They are usually very easy to see but as they approach the Sun these particles condense and become much harder to see. Suppose we discover a new comet on an orbit that brings it closer to the Sun than Mercury every 125 years. The birthplace of comets is a cloud of icy, dusty aggregates beyond the solar system. Why do we sometimes observe asteroids at the distances of the gaps in the asteroid belt?
