nergy . Appearance of four seasons, that is, spring, summer, fall, and winter, in a complete revolution of Earth around Sun is attributed to a fact that the earth's axis of rotation is tilted at 23.45 with respect to its elliptic orbit plane. Show this physical phenomenon by means of variation of the incident solar heat flux (i.e, solar energy per unit area) on the earth's surface in a yearly period. In addition, why is the summer time in the northen hemisphere ocured in the centh's revolution as it moves closer to the position of aphelion, instead of the position of perihelion? (20 points)Explanation / Answer
ANSWER:-phenomenon of sesons in earth with heat flux:-
the periodic change of climate over the months – is not a result of Earth approaching or moving away from the Sun. Seasonal climatic variations are due to the slight tilt of the Earth, which spins like a top tilted at an angle of 23.5 degrees in relation to its orbital path. This tilt explains why one hemisphere receives more sun than the other at a given time of year. If the Earth’s axis were not tilted, there would be no seasonal variations in temperature. Our climate in October would more or less resemble our climate in March
Solar energy is radiant light and heat from the Sun that is harnessed using a range of ... The Earth receives 174 petawatts (PW) of incoming solar radiation (insolation) which is gradually changes with earh inclination angle in northon hemispere and southern hemispehere different heat flux in unit area in year
why summeer time in northern hemisphere when closer to aphelion instead of perihelion :_
The Earth is tilted 23.5 degrees on its axis, a straight line through the planet from the North Pole to the South Pole. The Earth spins around, or rotates, on this axis as it orbits the sun. The key here is that as the Earth orbits the sun, different regions on Earth tilt both towards and away from the sun, depending on the region’s respective hemisphere. This causes the sun’s light and energy to hit the different regions of the Earth at different angles throughout the course of one orbit, or one full year.
by the angle of 23.5 in orbit when its in aphelion its shows more nothern hemisphere to sun more than sun hence summer happens in northen hemispehre
