Answer:
It is called pen and it is located at the dorsal side
Explanation:
Squid belongs to the class Cephalopoda, subclass Coleoidea which is characterized by internal shell (unlike subclass Nautiloidea in which shell is located externally).
The shell of the squid (the pen) in very reduced and small, formed from chitin and located at the dorsal side. The pen provides attachment for muscles and it gives the squid stiffness.
Most likely, this internal shell evolved from the external shell, because it is believed the ancestral of the organisms from the Coleoidea was probably nautiloid-like.

- Planet's Reflectivity
- Planets Surface (Through Greenhouse Effect)
The thickness of the atmosphere, seems to be part of it, and I belive that is true, as it plays a role in temperature, determening wether if it can help with how warm or cold a planet is.
A planet's distance from the sun definitly plays a role, becuase depending on how far or close a planet is to the sun, the warmer it can be.
Planet's Surface goes through the process of greenhouse effect, causing a(n) planet to be able to get hotter
