4. Why are summer days in Texas warmer than winter days in Texas? (A) Because sunlight strikes the Northern Hemisphere directly during summer (B) Because sunlight strikes the Northern Hemisphere indirectly during (C) Because Texas is closer to the equator at that time (D) Because it's before the summer solstice

The summer days in Texas are warmer primarily due to the angle of sunlight. During summer, the Northern Hemisphere tilts towards the sun, resulting in sunlight striking the region more directly. This means that the energy from the sun is more concentrated, leading to those sizzling summer days we all know! In contrast, during winter, the Northern Hemisphere tilts away from the sun. This causes sunlight to strike at a much shallower angle, spreading the energy over a larger area, resulting in cooler temperatures. So, you can thank the tilt of the Earth for your toasty summers and brisk winters in Texas!
