Answer:
<em>They orbit the Sun.</em>
<em></em>
Explanation:
Asteroids are small planetary bodies, too small to be classified as a planet. Asteroids are made up of rocky materials, and they orbit the sun. In our solar system, a vast number of asteroids exists together in the 'great asteroid belt' a region between the orbit of Mars and Jupiter. A comet is a ball of frozen gas, rocks and dusts, that travels around the sun in the solar system. Comets can be as big as a small town. When the orbit of a comet brings it close to the sun, it melts, leaving a trail of gas behind it. This trail of gas is the characteristic long tail of a wishing star seen in the sky in some clear night.
<em>The common property of a comet and an asteroid is that they both travel around the sun in the solar system, just like every other planetary body in the solar system.</em>
<u>Answer:</u>
All of the above mentioned options can be used by scientists to date the sediment layer they are found in.
<u>Explanation:</u>
- Rock fossils, animal fossils, etc.found in the sediment layer can be used to determine the age of the sediment based on the period of the existence of that animal or the period of formation of the rock.
- Tree rings clearly exhibit the age of the tree. Hence, a sediment layer with the evidence of tree rings can tell the age of the sediment layer.
- An amalgamation of the data obtained from the animal growth rings and the period of existence of that specific animal species can be used to calculate the age of the sediment.
- The intensity of radioactivity left in the isotopes clarifies how old the isotope is.
- The age of mineral elements can be determined exactly with the help of processes like Potassium-Argon dating, Uranium-Lead dating, etc.
- Thus it would be easy to determine the age of the sediment layer containing mineral elements.
