Does the tidal effect act on the molten liquid core of the Earth?
The Earth is solid only over a thin portion of its surface. Most of the inner portion of the Earth is hot liquid material, which is also affected by the tidal forces in the same way as the oceans of water on the surface.
The tidal effect on the liquid core of the Earth influences geological activity such as earthquakes, volcanic eruptions and the gradual drifting apart of the continents.
Does the tidal effect apply to human beings on Earth?
Yes. Your weight on Earth will vary slightly decrease when the Moon is directly overhead.
What is the frequency of the ocean tides on Earth?
One high tide occurs approximately every 12.5 hours followed by a low tide.
What are spring tides?
Spring tides are the maximum tides. They occur when the Sun is in line with the Moon, resulting in a maximum combined tidal effect.
What are neap tides?
Neap tides are the minimum tides. They occur when the Moon, Earth and Sun from right angles, resulting in a minimum combined tidal effect.
Are spring tides and neap tides related to the seasons such as spring, summer, etc.?
No.
