Урок английского языка для 10 класса с астрономическими терминами

During the spring (vernal) and autumn (autumnal) equinoxes, the sun’s rays are directly over the equator. Equinox means “equal night” and day and night are about equal all over the world. Due to the tilt of the earth’s axis, the sun’s rays are more directly over the Northern Hemisphere in the spring and summer, and directly over the Tropic of Cancer at the time of the Summer Solstice, which is June 20th at 10:04 PM PDT this year.

Summer begins tomorrow! The sun’s rays will be directly over the Tropic of Cancer on June 20th at precisely 10:04 PM which means that the astronomical summer begins at this time. Solstices occur twice a year -- once when the sun reaches the highest point in the sky (Summer), and once when the sun is at its lowest point in the sky (Winter).

The Winter Solstice. Winter “officially” begins! The sun’s rays will be directly over the Tropic of Capricorn in the southern hemisphere. It marks the day of the year with the least hours of daylight in the northern hemisphere. Solstices occur twice a year -- once when the sun reaches the highest point in the sky (Summer), and once when the sun is at its lowest point in the sky (Winter).

During the autumn (autumnal) and spring (vernal) equinoxes, the sun’s rays are directly over the equator. Equinox means “equal night” and day and night are about equal all over the world. Due to the tilt of the earth’s axis, the sun’s rays are more directly over the Southern Hemisphere in the autumn (fall) and winter seasons, and directly over the Tropic of Capricorn at the time of the Winter Solstice, which is December 21st at 9:11 AM PST this year.
