True
yes
It is cold all of the time, with temperature always in the negatives.
Under normal conditions, yes.
Because the temperature is often a few degrees colder right at the surface. This is because cold air sinks, and if it is not mixed (as under calm conditions) the temperature will be colder at the surface than it is 2 meters above ground, where temperature is officially measured.
"Trade winds diminish in the Central and Western Pacific. The thermocline is depressed in the east and elevated in the west. Sea surface temperatures stay high when usually, the temperature drops in the Eastern Pacific. (The thermocline is a drop in sea temperature.)" NOAA Research; El Nino Activity Key
No, its brittle under the stress and temperature conditions found at or near the Earth's surface. However if "stressed" it is piezoelectric.
Surface temperature is the temperature on the outside of the object. For example the surface temperature of the Earth is the Ground temperature and the surface temperature of an orange is the rind not the pips.
what is the sirius surface temperature
Why do they have different surface temperature
Surface temperature? Saturn probably doesn't HAVE a "surface".
its so fat that if it had surface conditions it would explode.
Very hot: the surface temperature of the sun, by comparison, is "only" 5,500 deg C.
