Both comet types come from some location near the ecliptic plane of the Solar System, but the long-period comets come from farth
er away. B. Both comet types come from random directions in a spherical distribution around the Sun, but the long-period comets come from farther away. C. Short-period comets come from a random direction in a spherical distribution around the Sun, and long-period comets come from farther away, in some location near the ecliptic plane of the Solar System. D. Short-period comets come from some location near the ecliptic plane of the Solar System, and long-period comets come from farther away, with random directions in a spherical distribution around the Sun.
D. Short-period comets come from some location near the ecliptic plane of the Solar System, and long-period comets come from farther away, with random directions in a spherical distribution around the Sun.
Explanation:
A comet is an icy rocky and small system body that passe near the sun get warmed and begins to release gases and is due to the effects of the solar radiation and have a highly eccentric elliptical orbit.
The long-period comets are those that have more than 200 yeas to complete and originate from the Oort Cloud.
And the short periods of comets are those that have less than 200 days of orbital periods as they have a low inclination.
The periods are less than 20 years and they are subject to a gravitational disturbance around larger bodies.
the process by which Earth makes heat is called radioactive decay. it involves the disintegration of natural radioactive elements inside Earth. ex; uranium is a special kind of element because when it decays, heat is produced from it
