answer choices . These two water bulges on opposite sides of the Earth aligned with the Moon are thehigh tides. torques. 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. The moon appears full when the Earth is between the moon and the sun. Key Concepts and Summary. Tidal bulges on the Moon involve the concept of. 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. magnetism. This means that high tides are a little higher and low tides … slight water on the Moon. the Moon), and the primary planet that it orbits (e.g. a cosmic coincidence. 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. Tidal energy is derived from the motion of the Earth-Moon system. I believe that your explanation of the tidal bulge on the side of the Earth farthest from the Moon is unnecessarily complicated. The twice-daily ocean tides are primarily the result of the Moon’s differential force on the material of Earth’s crust and ocean. Report an issue . Tidal acceleration is an effect of the tidal forces between an orbiting natural satellite (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. (2) The varying physical distances of the Moon and Sun, demonstrated by higher tides in December-January. This bulge is the high tide beneath the Moon. I have just been reading (and enjoying) the chapter of your book that deals with tides. Think of it this way: There are three points on the Earth. As we’ve just seen, the Earth's two tidal bulges are aligned with the positions of the moon and the sun. The Moon’s gravity then pulls the Earth toward it, leaving the water on the opposite side of the planet behind. Over time, the positions of these celestial bodies change relative to the Earth’s equator. Due to the rotation of earth, the bulges of tides are always ahead of the position on earth right under the moon. 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. Tags: Question 40 . 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. 30 seconds . The gravitational force between this portion of water and moon generates a torque that decelerates the rotation of earth. I believe that your explanation of the tidal bulge on the side of the Earth farthest from the Moon is unnecessarily complicated. 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. These tidal forces cause ocean water to flow into two tidal bulges on opposite sides of Earth; each day, Earth rotates through these bulges. This creates a second high tide bulge on the opposite side of Earth from the Moon. Q. One side of the Moon continually facing Earth is. answer choices . elasticity. I have just been reading (and enjoying) the chapter of your book that deals with tides. The changes in their relative positions have a direct effect on daily tidal heights and tidal current intensity. tidal … a passing phenomenon. (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). 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. SURVEY .
