• We live in the Northern hemisphere.
• The Earth rotates in a counterclockwise
  direction.
• Therefore the sun appears to rise in the east and
  set in the west.
• Solar noon is when the sun is at the highest
  position in the sky.
• From sunrise to solar noon the sun is moving
  higher in the sky. After solar noon the sun is
  moving lower in the sky towards the horizon.

From sunrise to solar noon the sun is moving
higher in the sky. After solar noon the sun is
moving lower in the sky towards the horizon.The
angle of separation is the angle formed from the
horizon to the suns position. The closer the
sun is to solar noon, the greater/larger the
angle of separation. The closer the sun is to
the horizon, the smaller the angle of separation.

The changing length and position of shadows
depends on three things1. Time of year2.
Geographic location3. Time of day
9
Shadows appear in the opposite direction of where
the sun is located. For example if the sun is in
the east, the shadow will point toward the west.
This means that shadows point west in the
morning and east in the afternoon.
10
The sun is a farther distance away from Earth in
the summer and closer in the winter.If the sun
is farther away in the summer then the shadow at
solar noon would be shorter than the shadow at
solar noon in the winter.
