effects of revolution ?
Answers
Answer:
Effects of Earth's revolution include the seasons and variation in the length of days and nights. In addition to revolution, the tilt of Earth's axis relative to its plane of orbit has a profound effect on Earth. At almost any given time, one hemisphere is tilted toward the sun, as the other is tilted away.
Answer:
Effects of Earth’s revolution include the seasons and variation in the length
of days and nights. In addition to revolution, the tilt of Earth’s axis relative
to its plane of orbit has a profound effect on Earth. At almost any given
time, one hemisphere is tilted toward the sun, as the other is tilted away.
The hemisphere tilted toward the sun receives more direct sunlight and
thus has warmer temperatures and longer days. The hemisphere tilted
away from the sun receives indirect sunlight. That hemisphere has cooler
temperatures and shorter days.
The changes in hours of daylight and in temperature caused by
revolution and tilt lead to the yearly change of seasons at middle latitudes.
If Earth’s axis were perpendicular to its plane of orbit, seasons would not
occur. In addition, every place on Earth’s surface would experience 12 hours
of daylight and 12 hours of darkness every day. On the other hand, if Earth’s
axis were tilted more than 23.5°, each hemisphere would experience hotter
summers and colder winters.
The first day of summer in the Northern Hemisphere occurs on or
about June 21 each year. This day has the longest daylight period, because
the sun’s path in the sky is longer and higher than at any other time of the
year. The point at which this daily increase stops is the summer solstice
(SOHL-stihs). At the summer solstice the Northern Hemisphere is at its
maximum tilt toward the sun. Because this tilt is equal to 23.5°, the sun is
straight overhead at locations along the latitude line of 23.5° N. This
latitude line is called the Tropic of Cancer.
On the first day of summer, every point on Earth within 23.5° of the
North Pole experiences 24 hours of daylight. The boundary of this region,
at latitude 66.5° N, is the Arctic Circle. On June 21 in the Southern
Hemisphere, every point south of the Antarctic Circle (latitude 66.5° S )
experiences 24 hours of darkness.
