Which celestial body has a greater effect on tidal forces on earth?
The moon has a greater effect on tidal forces on Earth compared to the sun. This is because the moon is closer to Earth and exerts a stronger gravitational pull, causing the tides to be primarily influenced by the moon's position.
What are 2 effects of earths gravitational pull on the moon?
Earth's gravitational pull keeps the Moon in a stable orbit, preventing it from drifting away into space. Additionally, this gravitational force causes tidal effects on both Earth and the Moon, leading to phenomena such as ocean tides on Earth and slight bulging of the Moon's surface.
How many tidal bulges are there on earth at one time?
There are typically two tidal bulges on Earth at any given time, one on the side facing the moon and one on the side opposite the moon. This is due to the gravitational force exerted by the moon on the Earth's oceans, causing them to bulge.
Why do you see the same aide of the moon always?
The Moon has a bound rotation, meaning that it takes just as long to orbit Earth (ca. 27 1/2 days) as it takes to rotate around its axis. Most moons do that. The reason for the bound rotation is related to tidal forces. Earth is also slowing down in its rotation, due to similar tidal forces, until one far day in the future, Earth will always show the same side to the Moon.
Where does the energy for geothermal nuclear and tidal come from?
1. Geothermal - comes from the earth's internal heat. Opinions differ somewhat on where this comes from, but it seems to be accepted that this is partly heat left from the very hot rocks the earth was formed from, and partly from radioactivity deep in the earth. 2. Nuclear - comes from fission of nuclei of uranium and plutonium, which releases energy because mass is destroyed. 3. Tidal - comes from gravitational effects of the sun and moon on the oceans
Why does the moon exhibit a much stronger tidal effect on Earth than does Jupiter?
This is because Jupiter is much farther away. This equation measures the Force (F) in Newtons that two objects have on each other. F=G (m1m2)/R R is distance. M1 is the mass of object 1, m2 is the mass of object 2, and G is the gravitational constant.
What is the sun's effect on the Earth and Moon?
1. Tidal effect: the moon's gravitational force affects the oceans tides. 2. The earth wobbles slightly on its axis due to the force of the moon on the earth. 3. The earth is very slightly lopsided. 4. Electromagnetic forces between the earth and moon interact with each other, although the moon's magnetic field is very weak in comparison to that of the earth.
Why does the moon move away from the earth each year when the earths gravity was supposed to pull the moon back?
This one's slightly complicated, so bear with me! I find diagrams help a lot, so since I can't put them in here, get a pencil and paper out and see if you can sketch what's going on in steps 1-4 if it helps you understand. 1) The Moon's gravity causes tides on Earth. In theory, the tidal bulge (where the water piles up) should be directly under the Moon. 2) However, Earth is spinning, which carries the tidal bulge forward a bit. So in reality, the tidal bulge is slightly ahead of the Moon. 3) The tidal bulge has a very small gravitational pull of its own, which pulls the Moon forwards in its orbit. This causes the Moon to speed up. 4) Newton's laws show that anything in an orbit that speeds up will move out higher into a bigger orbit, so the Moon gradually moves away. This effect isn't much, only about 3cm a year - that's about the same speed the plates drift across the Earth, or that your fingernails grow. However, it does mean that when the Moon formed, around 4.6 billion years ago, it was 20 times closer to Earth than it is now! This has even more implications, however: 5) At the same time as the bulge pulls the Moon forward and speeds it up, the Moon pulls the tidal bulge backwards, and slows it down. Friction between the ocean and the Earth beneath causes the Earth's rotation to slow down, too. So in effect, energy is being transferred from Earth to the Moon. Earth slows down, the Moon speeds up, and moves further away.
What is the tidal range of a neap tide?
The tidal range of a neap tide is typically smaller than that of a spring tide. During neap tides, which occur when the sun and moon are at right angles relative to the Earth, the difference between high and low tides can be about 1 to 2 meters (3 to 6 feet), depending on the location. This reduced tidal range results from the gravitational forces of the sun and moon partially canceling each other out.
Why does the moons gravity have more affect on earth than the suns gravity?
Strictly speaking, it does not. However, the moon does have a greater influence on the tides. Tides are not simply the result of the Moon's gravity. Rather, they occur because the strength of gravity decreases with distance, which means that the moon exerts a stronger gravitational pull on the water on the side facing it than it does at the average point on Earth. Such effects are called tidal forces. Gravity from an object is directly proportional to its mass and inversely proportional to the square of the distance. This means if you double the mass you double the gravity. If you double the distance, gravity is reduce to 1/4 the original value. If yo triple your distance, gravity is reduced to 1/9 and so on. Tidal forces are also directly proportional to mass but are inversely proportional to the cube of the distance, so if you double your distance you reduce tidal forces to 1/8. If you triple the distance, you reduce them to 1/27. So let's do the math. The sun is about 27 million (27,000,000) times the mass of the moon and about 390 times farther away from Earth than the moon is. First, to calculate the ratio of gravitational force: 27,000,000/(390^2) ≈ 27,000,000/152000 ≈ 178. So the sun's gravity exerts nearly 180 times more force on Earth than the moon's gravity does. However if we calculate the ratio of tidal forces 27,000,000/(390^3) ≈ 27,000,000/59,300,000 ≈ 0.455. So the moon's tidal forces on the Earth are a little more than twice those exerted by the sun.
What is earths moons diameter?
2½ Moon Diameter = Earth's Diameter- 1 Moon Diameter. Earth's Diameter = 7/2 Moon
Conservation of tidal energy?
Perhaps you mean the use of such energy as a source of renewable energy? It is believed that the work of tidal power slows the rotation of the Earth, which can lead to negative environmental effects. However, given the enormous mass of the Earth influence of tidal power is negligible. The kinetic energy of rotation of the Earth (ten to the twenty-ninth degree of J) is so great that the work of the tidal stations with total capacity of 1,000 GW will increase the duration of the day only ten to the minus fourteenth degree seconds per year, which is 9 orders of magnitude less than the natural tidal braking (~ 2 × ten to the minus fifth degree with a year)
