Near the epicenter
Because the epicenter it is the area where the earthquake start
if you are not aware what emissivity is defined as the ratio of the energy radiated from a material's surface to that radiated from a blackbody (a perfect emitter) at the same temperature and wavelength and under the same viewing conditions. it is a dimensionless number between 0 (for a perfect reflector) and 1 (for a perfect emitter).
it is the measure of how an object radiates heat.
the higher the emissivity “ε” the higher the temperature it emits. the perfect emitter of heat is called a “black body.”
a black body has an emissivity ε measure of 1.
for the emissivity of
therefore, water would emit more heat than of the sand.
answer: because the act of chewing on nails reportedly relieves stress, tension, or boredom. People who habitually bite their nails often report that they do so when they feel nervous, bored, lonely, or even hungry.
