Though the moon is smaller it is much closer. Therefore it has a larger impact on tides than the sun.
about 6 hours
Occur when the sun moon and earth are aligned in a triangular shape. The high tides are not as high as the spring tides during this time.
Occur when the moon, earth and sun are aligned. The high tides are considerably higher during this time. The sun's gravity also pulls on the ocean during this time.
Due to the gravitational pull of the moon.
Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune
The sun is substantially larger than all of the planets combined
Mercury, Venus, Earth, Mars. They are small and rocky.
Jupiter, Saturn, Uranus, Neptune. Made of gas and very large.
The earth spins on its axis every 24 hours causing approximately 12 hours of sunlight on each side.
The part of the moon that is seen from earth increases
When we cannot see the moon from earth.
The part of the moon that is seen from earth appears to be decreasing.
We can only see one side of the moon because it's revolution is the same rate as the rotation.
The moon revolves around the earth. The sun shines on different parts of the moon which makes it appear to change shape.
When an object makes an orbit around another object.
When an object spins on an axis.
About 365 days.
We have day and night due to the earth spinning on it's axis as it revolves around the sun.
Seasons occur on earth due to the tilt of the earth's axis.
