How do the relative motions of the earth sun and moon lead to eclipses?

The Earth goes round the Sun in an orbit, while the Moon travels round the Earth. If those orbits were in exactly the same plane we would have a solar eclipse at every new Moon and a lunar eclipse at every Full Moon.
The Moon's orbit is at an angle to the Earth's, so at most full/new moons the Moon is above or below the plane of the Earth's orbit (known as the ecliptic).
But if the Moon is crossing the ecliptic at full or new moon, we get an eclipse.

Is the amount of gravity between 1 kg of lead and earth?
The mutual gravitational force that attracts 1 kg of lead and the earth to each other is 9.8 newtons (2.205 pounds).
Is The currently accepted age of Earth is approximately 4.5 million years?
Clair Cameron Patterson was an American geochemist who estimated the age of the earth as 4. 55 years old. He developed the uranium-lead dating method into lead-lead dating method.
What are extremely large explosions on the sun that can lead to geomagnetic storms on Earth?
Solar flares
What do electrically charged particles from the sun strike in the earth's magnetosphere to lead to the production of the sheets of light known auroras?
They strike the magnetic field generated by the Earth.
What affect does gravity have on all matter in the universe?
Because of the existence of 'gravity', there are a pair of equal forces between every two specks of mass in the universe. Greater masses and smaller separations result in greater forces. These simple facts lead to the formation of galaxies, stars, and planets, and to virtually all of the motions we see, including orbits.
Is lead part of the Earth?
The element lead is part of the Earth. The lead that we use in everyday things is mined from the Earth.
Why do pencils have numbers?
The numbers indicate the relative hardness of the pencil lead.
Is lead on Earth?
yup
What is the element for lead and how abundant is it on earth?
There are more than 1.5 billion tons of lead on Earth.
Is lead found on earth?
yup
Which is greater the attraction of the earth for a kilogram of lead or the attraction of a kilogram of lead for the earth?
They are exactly equal . . . an important concept in understanding gravity.
Why can't the eclipses be drawn on scale?
They could, theoretically. However... * The Sun's diameter is about a hundred times larger than that of Earth. * The Sun is a long way from Earth compared to the Sun's diameter: again, very roughly speaking, by about a factor of a hundred. * The Moon is even smaller than Earth: about a quarter the size of Earth. * The Moon is even further from Earth relative to its diameter: here, it's something like 220 times the diameter of the Moon away. To fit all this on a piece of posterboard roughly a meter across, you'd need to make the Sun a 1 cm circle; the Earth would be a 0.1 mm circle (this is about a fifth the size of the lead in an extremely fine point mechanical pencil), and the Moon would be about 0.028 mm across and about 6 mm from Earth. It's obviously going to be difficult to even see the Moon without a magnifying glass, let alone make out any details of what's going on.
Does gravity have an affect on the potential difference of a battery?
No.AnswerPresumably, you mean 'specific gravity' or, as it is known these days, 'relative density'? If so, the relative density of a lead-acid cell or battery is, indeed, a guide to that battery's state of charge -that's why we use a hydrometer to check the condition of a lead-acid battery. However, it would be wrong to say that the relative density of a lead-acid battery 'effects' the voltage -it merely is a guide to the state of charge. (Actually, it's the state of a battery's charge that affects its relative density.)
Why is there lead in my Christmas tree?
Lead comes from the earth. Of course, everglades (real Christmas trees) are made from the earth, so during the time that the trees were growing, lead contaminated it. If you have an artificial tree, during the making, packaging, or shipping lead may have entered it. It could also be the fact that the materials ( plastics, coloring, ect.) made from the earth could of contained lead.
What type of jobs can lead to carpal tunnel syndrome?
Certain jobs which require repeated strong wrist motions carry a relatively high risk of carpal tunnel syndrome.
Would 1 kg of lead and earth be bigger then marshmallows and earth?
No, it wouldn't. Eath is much larger no matter how many kg of lead there is. Mashmallows are much too small. Earth is very big.
What is the relative atomic mass of lead?
The element lead consists of four naturally occurring isotopes with atomic masses 203.97302, 205.97444, 206.97587, and 207.97663 . The relative abundances of these four isotopes are 1.4, 24.1, 22.1, and 52.4%, respectively.
