Theory that the Earth was the center of the Universe by Ptolemy (incorrect)
Theory that the sun is the center of the Universe by Copernicus. Explained the motion of the planets. Verified that the planets orbit.
The pendulum swings in a fixed direction in space, while the Earth ROTATES under the pendulum.

Evidence of Earth's Revolution
-seasons change throughout the year.
-Different constellations are seen throughout the year.
is a group of stars that form a pattern.
Seasons are caused by
the tilt of the earth's axis & the revolution around the sun
when the sun reaches its highest position in the sky.
Over the course of an entire year

the point directly over your head.

cyclic events and very predictable.
How long does a high tide occur?
approximately every 12 hours and 25 minutes
How long does a low tide occur?
approximately every 12 hours and 25 minutes.
How many high/low tides are there everyday?
2 high tides and 2 low tides
When the moon and the Sun are in line with the Earth, the gravitational pull is at its greatest causing very HIGH tides and very LOW tides. (Full moon and New moon)
When the moon and the Earth are at 90 degree angles, the gravitational pull causes very average tides. (First Quarter and Third Quarter phases)
is an astronomical event that occurs when an astronomical object is temporarily obscured, either by passing into the shadow of another body or by having another body pass between it and the viewer.
Every month we don't have an eclipse because
the moon's orbit is tilted 5 degrees.
