Study Notes
Tidal Forces
- The force that changes the levels of the oceans is known as tidal force.
- The mutual force between Earth and the moon is gravitational force.
- Gravitational force is responsible for much more than just the changing levels of the oceans.
- Tidal force is the difference in the strength of gravity between two points on a body.
Effects of Tidal Forces
- Tidal forces cause the oceans to flow into bulges on the side of the Earth facing the moon.
- They also cause the oceans to bulge out on the opposite side of the Earth, away from the moon.
- Tidal forces cause the levels of the oceans to rise and fall, resulting in tides.
Tidal Bulges
- The deformation of a body stemming from tidal forces is called a tidal bulge.
- Tidal bulges are less pronounced in the solid parts of the Earth compared to the oceans because the solid Earth is more rigid and resistant to deformation.
Tides on Earth
- The sun also influences the oceans, along with the moon, and this combined effect causes the tides to rise and fall.
- The alignment of the moon, sun, and Earth at full moon and new moon causes spring tides, resulting in higher high tides and lower low tides.
- The misalignment of the moon, sun, and Earth at quarter moon causes neap tides, resulting in lower high tides and higher low tides.
- The rotation of the Earth causes the tides to rise and fall twice in 24 hours.
Moon's Orbit
- The moon's orbit is not a perfect circle, which causes the tides on Earth to be slightly ahead compared to prior images.
