If the Earth were a disk with its surface perpendicular to the rays of sunlight, each point on it would receive the same amount of radiation. <span> However, the Earth is a sphere and aside from the part closest to the sun, where the rays of sunlight are perpendicular to the ground, its surface tilts with respect to the incoming rays of energy with the regions furthest away. Hope this answers the question.</span>

Answer:
Higher heat of evaporation required to break hydrogen bonds
Explanation:
Water molecules are joined together by intermolecular hydrogen bonding. Evaporation of liquid water into water vapor requires extra energy to break these hydrogen bonds to separate the water molecules from each other.
Since a higher heat of evaporation is required, the water molecules absorb the heat from the skin surface or leaf surfaces during perspiration and transpiration respectively. This leaves the cooler skin and leaf surfaces behind. Therefore, the presence of intermolecular hydrogen bonds and the need for extra energy to evaporation water allow it to exhibit a cooling effect.
Answer:
At present Earth is tilted 23.5 degrees on its axis. This is the primary reason for the seasons. When the Earth is tilted toward the sun the Northern Hemisphere is in the warm season and when the Earth is tilted away from the sun the Northern Hemisphere is in the cool season. Since the Earth revolves at a predictable and relatively steady rate around the sun the cycle repeats itself every year. In the warm season the sun is higher in the sky and it is warmer and in the cool season the sun is lower in the sky and it is cooler.
What if though the Earth was not tilted? In this case the plane of the Earth's poles would always be perpendicular to the sun. The sun would always be just on the horizon 24 hours a day on every day at the poles. Every day would be like what it currently is on the equinox since every location on Earth would have about a 12 hour sunlight days and the noon sun angle would be about the same every day. There would no longer be season as we know them. The temperature and precipitation pattern would not vary much. It would still be warm at the equator and cold at the poles. The most profound impact on temperatures would be at the poles. Instead and dark and frigid temperatures in the winter and warmer and constant sun in the summer, the polar areas would have much more uniform temperatures year round and the sun would always be low on the horizon. Across the Earth it would be like it is in the middle of fall or spring but it would last all year every year. Areas today that have wet, dry, warm and cold seasons would have a fairly constant weather all year whether it be wet, dry, warm and/or cold.
you can choose whichever paragraph you want, i just put two just in case. hope this helps :)
