A comet is a lump of rock and ice. Spacecraft have flown by comets. A comet only has a tail when it is near the sun. Most comets come from the Kuiper belt. A comet has actually been witnessed hitting a planet. Most comets have short orbital periods.
A comet is a tiny, frozen entity in the Solar System that heats up and starts to emit gases as it approaches the Sun. This process is known as outgassing. This results in an apparent atmosphere or coma, and occasionally a tail as well. These occurrences are caused by how the solar wind and solar radiation interact with the comet's nucleus.
The size of comet nuclei varies between a few hundred meters and tens of kilometers, and they are made up of loose clumps of ice, dust, and tiny rocky particles. A comet's orbit is typically very eccentric and elliptical, and its orbital period can range from a few years to possibly millions of years.

Cylindrical map projections , conic map projections , & azimuthal map projections.
Answer:
sedimentary (ex: limestone), metamorphic (ex: marble), igneous (ex: granite)
Explanation:
sedimentary, metamorphic, and igneous are the 3 types of rocks formed by the rock cycle. didnt know if you only needed that or examples of each kind so I gave both. also not important but a fun fact igneous means made by fire, metamorphic (think of a butterfly, they go through metamorphosis) this means they change, and sedimentary (rocks pressed together to form a new one often found after events such as erosion, etc). hope this helps :)
