Choose all that apply about comets:Group of answer choicesComets grow tails only when they approach the Sun.Comets in plane of the Solar System come from Kuiper belt.Comets with randomnly oriented orbits come from Oort cloud.
Solution
-
Comets grow tails only when they approach the Sun: This statement is true. As a comet gets closer to the sun, the heat causes the comet's ices to vaporize and create a tail that points away from the sun.
-
Comets in plane of the Solar System come from Kuiper belt: This statement is also true. The Kuiper Belt is a region of the solar system beyond the orbit of Neptune, believed to contain many comets, asteroids, and other small bodies made largely of ice. Comets from the Kuiper Belt are also known as short-period comets, because they have orbits that take less than 200 years to complete.
-
Comets with randomly oriented orbits come from Oort cloud: This statement is true as well. The Oort Cloud is a theoretical cloud of predominantly icy planetesimals proposed to surround the Sun at distances ranging from 2000 to 200,000 AU. It is divided into two regions: a disc-shaped inner Oort cloud and a spherical outer Oort cloud. Comets from the Oort Cloud can have any orientation around the sun, which means their orbits can appear randomly oriented.
