Detailed explanation-1: -Rough surface will increase the surface area and thus provide more opportunities for absorption as compared to the smooth surface. If the absorption rate would be higher, than the rate of radiating energy back to the space would also be higher for the dark and rough surface area.

Detailed explanation-2: -Dark surfaces absorb more insolation than light surfaces. As a result they heat up faster.

Detailed explanation-3: -At the Equator there is a year round gain of Insolation and this region gains the most Insolation of all of the locations on the globe. The amount of Insolation at the Equator also varies little throughout the year.

Detailed explanation-4: -Because Earth is much cooler than the Sun, it re-radiates energy as longwave, lower-energy wavelengths than it absorbs. This absorbed energy is re-radiated as infrared radiation, which we feel as heat.

Detailed explanation-5: -Most of the solar radiation is absorbed by the atmosphere and much of what reaches the earth’s surface is radiated back into the atmosphere to become heat energy. Dark colored objects, such as asphalt, absorb radiant energy faster than light colored objects.
