Do tides affect a glass of water?
Ultimately, the only way a tide could appear in the glass of water is for both the water and the glass to extend so far that different parts of them feel different gravitational effects from the Moon, causing them to deform their shape.
What causes the water on the opposite side of the Earth to rise up during high tide?
Gravity and inertia act in opposition on the Earth’s oceans, creating tidal bulges on opposite sites of the planet. On the “near” side of the Earth (the side facing the moon), the gravitational force of the moon pulls the ocean’s waters toward it, creating one bulge.
Why do tides change?
Because the gravitational pull of the moon is weaker on the far side of the Earth, inertia wins, the ocean bulges out and high tide occurs. As the Earth spins, different areas of the planet face the moon, and this rotation causes the tides to cycle around the planet.
What makes the tide change?
Tides are very long waves that move across the oceans. They are caused by the gravitational forces exerted on the earth by the moon, and to a lesser extent, the sun. Because the gravitational pull of the moon is weaker on the far side of the Earth, inertia wins, the ocean bulges out and high tide occurs.
How changes in the relative positions of the moon and sun change in relation to the Earth?
As the moon revolves around the Earth, its angle increases and decreases in relation to the equator. This is known as its declination. Similarly, the sun’s relative position to the equator changes over the course of a year as the Earth rotates around it. The sun’s declination affects the seasons as well as the tides.
How do the rotation of the Earth and gravitational pull causes movement of ocean water explain?
The moon’s gravity pulls the ocean toward it during high high tides. During low high tides, the Earth itself is pulled slightly toward the moon, creating high tides on the opposite side of the planet. Earth’s rotation and the gravitational pull of the sun and moon create tides on our planet.
