there are no regions, i think.......
The core, radiative zone, tachocline, convective zone, transition region, corea, chromosphere, and photosphere are all of the regions of the sun.
All regions of the world that are near the equator get the most amount of sun during the day, but probably more colder during the night.
All lands north of the arctic circle (or south of the antarctic circle) will experience at least one day of the year where the sun never sets. This is know as 'the midnight sun.'
The mantle :-)
The polar regions get the least amount of warming rays from the Sun.
Delhi does experience the mid day Sun. ALL part of earth experience the mid day Sun (although the polar regions do not for 6 months of the year and sometimes clouds shade the Sun on some days.
Sun spots are just cooler regions of the Sun's surface, so they appear darker. A simplistic answer is that they are just a darker hue of the normal colour of the Sun. A more detailed answer is that they are all different, depending on the visual perceptual property and who the observer is - as all observers will see a different value depending on their spectral sensitivity. See the related link of a sun spot, and draw your own conclusions.
Different parts of the Sun rotate at different speeds, which is how we know that the Sun isn't a solid. The equatorial regions of the Sun rotate in about 27 days, but the polar regions take a little longer; about 33 days.
The regions close to the equator receive most energy from the Sun. The reason is that for observers in such regions, the Sun is higher in the sky.
Because they are furthest from the sun and the angle at which the sun's rays hit the polar regions is much shallower than at other regions.
North and south pole
The regions of some climates affects us from the regions of the sun in the air with all of the climates joining toghether it affects some states like New Jersey and lots more.
