The summer solstice (or estival solstice), also known as midsummer, occurs when a planet's rotational axis, in either northern or southern hemispheres, is most inclined toward the star that it orbits. Earth's maximum axial tilt toward the Sun is 23° 26′. This happens twice each year (once in each hemisphere), at which times the Sun reaches its highest position in the sky as seen from the north or the south pole.
<span>The appropriate answer is A. the hemisphere is is tilted toward the sun and the sun reaches its highest point in the sky. This usually occurs on June 20 or 21. At this time the northern hemisphere experiences its longest day. Summer in the nothern hemisphere means that the earth is tilted towards the sun and receives sun rays that are more direct. </span>
A oft-repeated water vapor myth is that warm air can “hold” more water vapor than cool air because as the air warms its molecules move farther apart, making room for more molecules
