(1) Solar tides, which can sum with the lunar tide to increase or reduce the bulges of water, creating a spring tide (Sun, Earth, Moon aligned) or a neap tide (Sun, Earth, Moon make 90 degree angle). The moon appears full when the Earth is between the moon and the sun. elasticity. magnetism. In both cases, the gravitational pull of the sun is "added" to the gravitational pull of the moon on Earth, causing the oceans to bulge a bit more than usual. Report an issue . Tags: Question 40 . a cosmic coincidence. The reason there is a bulge on the near side of the Earth is because the Moon (and the Sun's) gravity is stronger there. This means that high tides are a little higher and low tides … a passing phenomenon. Over time, the positions of these celestial bodies change relative to the Earth’s equator. Tidal bulges on the Moon involve the concept of. Tidal energy is derived from the motion of the Earth-Moon system. answer choices . torques. SURVEY . (2) The varying physical distances of the Moon and Sun, demonstrated by higher tides in December-January. I have just been reading (and enjoying) the chapter of your book that deals with tides. One side of the Moon continually facing Earth is. tidal … This creates a second high tide bulge on the opposite side of Earth from the Moon. The reason there's also a bulge on the far side of the Earth is...because the Moon's gravity is stronger on the near side of the Earth. As we’ve just seen, the Earth's two tidal bulges are aligned with the positions of the moon and the sun. This bulge is the high tide beneath the Moon. Key Concepts and Summary. I have just been reading (and enjoying) the chapter of your book that deals with tides. answer choices . 30 seconds . I believe that your explanation of the tidal bulge on the side of the Earth farthest from the Moon is unnecessarily complicated. The gravitational force between this portion of water and moon generates a torque that decelerates the rotation of earth. The changes in their relative positions have a direct effect on daily tidal heights and tidal current intensity. I believe that your explanation of the tidal bulge on the side of the Earth farthest from the Moon is unnecessarily complicated. When the Moon is at first quarter or last quarter (at right angles to the Sun’s direction), the tides produced by the Sun partially cancel the tides of the Moon, making them lower than usual. Think of it this way: There are three points on the Earth. Due to the rotation of earth, the bulges of tides are always ahead of the position on earth right under the moon. slight water on the Moon. the Moon), and the primary planet that it orbits (e.g. Spring tides are approximately the same, whether the Sun and Moon are on the same or opposite sides of Earth, because tidal bulges occur on both sides. The Sun also creates a tidal bulge because the Sun's gravitational force is a little bit stronger on the side of Earth that faces the Sun than it is on the side of Earth that faces away from the Sun. These tidal forces cause ocean water to flow into two tidal bulges on opposite sides of Earth; each day, Earth rotates through these bulges. A new study shows that the lunar far side highlands may be the result of tidal forces acting early in the moon's history when its solid outer crust floated on an ocean of liquid rock. The twice-daily ocean tides are primarily the result of the Moon’s differential force on the material of Earth’s crust and ocean. These two water bulges on opposite sides of the Earth aligned with the Moon are thehigh tides. Q. Earth).The acceleration causes a gradual recession of a satellite in a prograde orbit away from the primary, and a corresponding slowdown of the primary's rotation. The Moon’s gravity then pulls the Earth toward it, leaving the water on the opposite side of the planet behind. Tidal acceleration is an effect of the tidal forces between an orbiting natural satellite (e.g.
