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.

Habitat climate,warmer temperatures and increased radiation Hope this helps
The amount of heat they are exposed to has a lot to do with the inferences and observations that they make on the density of the earth's core. The inner core is the most compact due to the fact that they have a lot of direct exposure to heat and the gravity of the earth pressung down on it. The inner core is less subjected to those conditions.
The city state located on Peloponnese was Sparta.
Sparta was the only city state located on the southernmost part of Greece, on Peloponnese. It is one of the two best known city states along side Athens, and it was always one of the two strongest ancient Hellenic city-states.
Sparta though was not like the other city-states of the Hellenic world. While all others were developing some form of partial democracy, where orientated toward trade, science, Sparta was the total opposite. Sparta was ruled by a monarch. All the healthy boys were trained to serve the military and that was their only job in their lives. Most of the hard work was done by slaves. The women had role in the household but also the same rights as the men. The society was mostly striding toward self-sustaining, resembling and ancient type of socialism in a way.
