Yes. Comets do not enter the atmosphere of the earth (we hope!). What you see is gasses that are released from the comet, illuminated by the sun. However, a meteor (shooting star) is visible only due to the atmosphere heating the meteor.
No, meteors only burn up because of the friction caused as they pass rapidly through the atmosphere.
Nobody knows, really. Several comets are visible from Earth each year. Most of them have a long period and are not known in advance.
Because they hit Earth's surface and they hit whenever they go into Earh's atmosphere
Its surface is visible because of how AU's (Astronomical Units) it is away from the Earth.
Comets are flying bits of rock that don't enter the earth's atmosphere and meteors are flying bits of iron stone or stony iron. Also meteors do enter the earth's atmosphere.
approx 25% is reflected approx 20% is absorbed approx 55% pass through to Earth's surface (it burns) supposedly
The sky is the atmosphere of Earth and any visible part of the universe, as observed from Earths surface.

Electromagnetic radiation from the sun, most in the form of visible light.

The atmosphere is transparent to the visible light of the Sun. So it passes right through, only to get absorbed by the surface of the Earth.

Meteoroids generally do not pose much of a risk as they are generally small enough to burn up in the atmosphere, and do not reach the surface. Asteroids and comets are larger and can cause potentially catastrophic damage if they strike Earth.
A meteorode is a small particle of debris within our solar system. When the meteoroid enters our atmosphere is becomes a meteor. If it then lands on the earth it becomes a meteorite. Comets on the other hand are larger and are associated with a visible tail.
Can comets hit the Earth's surface? Yes but they would have to be above a certain size so as not to burn up high in our atmosphere. You shouldn't worry though ...
Volcanic eruptions and comets both contributed to bringing water and other gases to Earth's surface creating the atmosphere. Volcanic products created nutrient rich soils for plants to grow and if the comets were large enough, they could create large enough indentations for lakes and oceans to form.
how did water from the earth's surface get into the atmosphere
