Imagine you are the Earth.
Lean to the north; that is the Earth's tilt.
• At the beginning of Summer, you will be
leaning towards the Sun.
•
At the beginning of Autumn, the Sun will be on
your left.
•
At the beginning of Winter , you will be leaning
away from the Sun.
•
At the beginning of Spring , the Sun will be on

5. What is Kepler’s 1st Law?
The Earth's orbit is slightly elliptical
( Kepler’s 1st Law), so that the Earth is closer
to the Sun at some times, and farther away at
others.
Orbits of planets are elliptical or oval
This Kepler’s 1st law!
The point in the Earth's orbit when it is as the
greatest distance from the Sun is called the
aphelion. The point when the Earth is closest to the
Sun is called the perihelion.

A.The Earth’s revolution changes the Sun—
Earth gravitational pull.
B.The Earth’s rotation causes annual
changes in its surface temperatures.
C.The tilt of the Earth’s axis and its revolution

14. What is the difference
between Solstice and equinox?
The solstice are days of the year
with the longest period of day
(Summer Solstice) or the longest
period of night (Winter Solstice).
The equinox is the day in spring
and fall that the hours of light and
dark are equal.

5. What is Kepler’s 1st Law?
The Earth's orbit is slightly elliptical
( Kepler’s 1st Law), so that the Earth is closer
to the Sun at some times, and farther away at
others.
Orbits of planets are elliptical or oval
This Kepler’s 1st law!
The point in the Earth's orbit when it is as the
greatest distance from the Sun is called the
aphelion. The point when the Earth is closest to the
Sun is called the perihelion.

A.The Earth’s revolution changes the Sun—
Earth gravitational pull.
B.The Earth’s rotation causes annual
changes in its surface temperatures.
C.The tilt of the Earth’s axis and its revolution
around the sun produces seasons.

14. What is the difference
between Solstice and equinox?
The solstice are days of the year
with the longest period of day
(Summer Solstice) or the longest
period of night (Winter Solstice).
The equinox is the day in spring
and fall that the hours of light and
dark are equal.

Lean to the north; that is the Earth's tilt.
• At the beginning of Summer, you will be
leaning towards the Sun.
