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>
Mountains wouldn't not be mountains. If the world was flat, then that would necessarily mean that the tectonic plates won't shift or rub up against each other.
Las ideas culturales de la población se modifican y enriquecen con el tiempo debido al contacto entre diferentes grupos culturales.
