What: Tidal Forces
When: Twice a day
Where: The gravitational pull of the moon is on all bodies of water.
- Wind affects the waves, but the wind does not cause the tides.
- “Tides” are the daily changes in the level of ocean water at any given place.
- The main factor that causes tides is the gravitational pull of the Moon.
- Many tide times, charts, and tables are available to inform those interested in the high and low tides.
- The Moon creates “tidal bulges” as it rotates around the planet Earth.
- “High Tide” is always occurring somewhere on the planet earth, and on both the facing side and opposite the facing side.
- “Low Tide” is the water area between the two high tides, between the two bulges.
- The Sun also contributes to the tidal rise of waters.
* While the Sun is far more massive than the moon, it exerts less influence because of its distance away from the earth.
* When the Moon & the Sun align with the earth, the tidal effects are greater.
* They align twice a month — at full and new moons
* That combined effect is called “A Spring Tide.” (having nothing to do with the season of Spring)
* When the Sun is at a 90-degree angle to the Moon, it lessens the tidal pull. That is called a “Neap Tide.”

Our lives are designed to affect those around us. We are the ones who are closest to people in all the different spheres of activity. The Lord wants to line up with us, and exert his tremendous and massive pull on the lives of those we come in contact with, and when we share the Gospel . . . when the Son is lifted up — His pull is added to the sharing of His Word. . . . .
