The seasonal variations of temperature on any planet depend on the characteristics of the planet's orbit, atmosphere, and axial tilt. Extrasolar planets are not all the same and appear to come in even greater variety than what we see in our solar system.
The fact that its daytime and nighttime temperatures vary between -183C and +427C.
Mercury, the planet closest to the sun. Temperatures vary between about 400 and minus 180 degrees Celsius (750 and minus 290 degrees Fahrenheit) .
The atmosphere has a lower heat capacity.
We have no idea how many there may be in total, but as of mid-2010, evidence of over 400 had been detected. Today, in the enlightened present of 2013, rough estimates, of the number of planets in this universe, vary between 1,700,000,000,000,000,000,000 and 72,000,000,000,000,987,654,321. Only 1001 of these planets have actually been confirmed, all the others have inhabitants who pray to false idols and so are being eternally punished in torch orbits around their Suns.
temperatures don't vary.
The temperatures and precipitation vary with altitude in all the climatic zones.
Yes.
Land temperatures vary by as much as 140 degrees F (60 degrees C) year-round.
The atmosphere has a lower heat capacity.
No. Temperatures in Mexico vary due to topography (more specifically height) and the fact that it is a quite extensive country.
Temperatures on the moon vary so much because it has no atmosphere.
Temperatures vary so much because the moon does not have an atmosphere.
