(a) Summer solstice (b) Winter solstice (c) Equinox.
Answer: (a)
Summer solstice happens when the Northern Hemisphere leans towards the sun on June 21st. This makes the Tropic of Cancer directly under the sun's rays, causing those areas to get more warmth. However, places closer to the poles get less heat because the sun's rays come in at an angle. The North Pole tilts towards the sun, giving areas beyond the Arctic Circle constant daylight for about six months.
With a large part of the Northern Hemisphere getting sunlight, it's summer in the areas above the equator. On June 21st, these places experience the longest day and the shortest night. The Southern Hemisphere, on the other hand, has winter during this time, with longer nights and shorter days. This Earth position is called the summer solstice.
(b)
Winter solstice happens on December 22nd. During this time, the Tropic of Capricorn gets direct sunlight because the South Pole leans towards it. When the sun's rays go straight down at the Tropic of Capricorn, more of the Southern Hemisphere gets daylight. So, the Southern Hemisphere has summer with longer days and shorter nights. This specific Earth position is known as the winter solstice.
(c)
On March 21 and September 23, the sun's rays directly hit the equator. During this time, neither of the poles leans toward the sun. Because of this, the whole Earth has the same length of day and night. This event is called an equinox.
