what would happen if a comet collided with our planet?
I can visualize it harming the atmosphere before it makes its crash,
perhaps that was the cause of extinction of life years ago,such thing may cause eruption of volcano that sends intense level of atoms in the ozone layer and stop the penetration of sun rays,as a consequence, temperature drop down ,rains will be more repeated that the level of the sea would rise,an other effect of such collision is earthquake that could eradicate ail forms of existence all these are enough reasons for scientists to search more and more how to escape such a tragedy
meteor showers as some people call it
no, comets do not orbit Earth. If comets did orbit Earth, it would be Earths Moon's, but comets orbit the kuiper belt at the edge of the Solar System. Some times comets hit each other and get knocked out of their orbit and possibly hit a planet.
Most of the small meteors and space 'trash' burn up in the stratosphere. The moon also catches some of this debris and larger meteoroids and comets are often deflected away from us or captured by Jupiter but some day a large meteor or comet could hit us.
because debris avalanches occur in steep valleys, and are made up of more solid matter than debris flows. debris avalanches are the direct cause of debris flows, which are fluid flows of water, rock and sediment.
Words that describe Ocean Debris are: Icky, nasty, unhelpful, gross, etc.
pull apart the carborator and clean it of dirt and debris pull apart the carborator and clean it of dirt and debris
Interplanetary debris is leftover stuff from remmants of planets(Asteroids) or comets or metoroids
Comets
Short-period comets originate from the Kuiper Belt.
Oort cloud
It is comets.
Meteoroids, asteroids and comets.
There are tiny dust-sized particles in Earth's path around the Sun. These particles are usually leftovers from asteroids or comets.When Earth passes through these particles, they burn up in our atmosphere producing bright lines. This is called a meteor shower.. . .a group of meteors that have an orbit that intersects the orbit of Earth, resulting in a large number of meteors entering the atmosphere in a relatively short span of time. Said another way. . .Meteor showers typically come about due to temporarily high concentrations of sun-orbiting debris that crosses the orbital path of Earth and, hence, collide with her atmosphere.While there are no "comet groups", comets being invariably solitary, debris cast off from a comet during its close approach to the sun can participate as "meteoric" space junk that encounters Earth during a meteor shower. Meteor showers tend to arise from old comets that have broken up and spread out along the comet's orbit. A meteor shower happens when the Earth's orbit intersects one of these old comets' orbits. That is why the same shower happens around the same date each year, and the meteors in that shower all appear from the same 'radiant point'.
Comets, asteroids, planetoids, various dust and debris fields.
Meteroids could contain debris left by a comet, especially during a meteor shower.
Comets lose ice and dust each time they come near the sun, leaving behind trails of debris. Eventually, they can lose all their ices, with some turning into fragile, inactive objects similar to asteroids.
The moon's craters are impact craters, formed by collisions of interplanetary debris (asteroids, comets, etc.) with the surface of the moon.
