Many people observed that the

rose in the
east
and set in the
west

Earth's movement
1. Moves around its axis (
rotation
)
2. Moves around the sun (
revolution
)
View source
Rotation
Earth's
movement
around its
axis
View source
A complete rotation takes
23
hours
and
56
minutes
View source
Day-night cycle
Created by
Earth's rotation
View source
Earth's rotation
Affects the
temperature
on Earth within a day
View source
Day

Earth
where the
sun

around the
sun
View source
It takes
365.25

View source

four years
, an additional day is added to the calendar to compensate for the extra hours (
leap year
)
View source
Perihelion
Earth is
closest
to the sun
View source
Aphelion
Earth is
farthest
from the sun
View source
Earth's axis is tilted
23.5
degrees
View source
Earth's
tilt
Causes the
North Pole
and the South Pole to lean toward or
away
from the sun at different times of the year
View source
Winter in the Northern Hemisphere
When the North Pole is
farthest
or turned away from the sun, the area receives only indirect sunlight and gets
cold
View source
Summer in the Northern Hemisphere
When the North Pole is leaning
towards
the
sun,
the region receives direct sunlight
View source
Seasons
Bring different amounts of
sunlight
, affecting the
length
of the day
View source
Days are shortest in the
winter
and
longest
in the summer
View source
Distance from the equator
Greater effect of the amount of sunlight on the length of the day
View source
Angle
of
sun's rays
When they strike at a
90
degrees angle, energy and
temperatures
in these areas are at the highest
View source
At the equator, the sun's rays hit an angle between 23 degrees North and 23 degrees
South latitude
, the
heat
is intense
View source
Angle of sun's rays
The closer you are to the pole, the less intense the radiation and the colder the climate gets
View source
Celestial Equator
Imaginary circle created by projecting
Earth's equator
into space
View source
Solstices
Days when the sun is
farthest
from the northern and southern points above the
celestial equator
View source
Summer Solstice
Marks the beginning of summer, usually falls on June 21 or 22, the longest day of the year
View source
Winter Solstice
Marks the beginning of
winter
, usually falls on
December 21
or
22,
the shortest day of the year
View source
Ecliptic
Path of the apparent motion of the sun in the sky throughout the year as observed from
Earth
View source
Equinoxes
Occur when the ecliptic intersects the
celestial equator
, days on which night and day have
equal
duration
View source
Vernal Equinox
Occurs in
March
, marks the beginning of spring in the
Northern
Hemisphere and of autumn in Southern Hemisphere
View source
Autumnal Equinox
Occurs on
late September
, marks the beginning of autumn in the
Northern
Hemisphere and spring in the Southern Hemisphere
View source
Solar altitude
Varies during
solstices
and equinoxes because of the
change
in the relative orbital position of Earth with respect to the sun
View source
Solar Altitude
Apparent height of the sun in the sky, measured from either the northern or southern point along the horizon, maximum is
90
degrees when the sun is directly
overhead
