To find the distance between the Earth and Moon you would use Lunar distance. Lunar distance is the measurement from and to the Earth and Moon which calculates 238,900 miles
Find the distance from the earth to the moon, then the the distance from the earth to the sun, and simply subtract the both.
The Sun is at a mean distance of about 150 million kilometers from Earth. The Moon is at a mean distance of 380,000 kilometers from Earth. The direction at which you find them vary over time.
There are a few methods that one could use to measure the distance between the moon and the earth. The easiest one that I can think of is this: Place a mirror on the moon, shine a laser on it and time how long it takes for the light from the laser to the moon and back again. Take this number and multiply by the speed of light Actually, NASA did exactly this on the Apollo 11 mission! Before Neil Armstrong & co. departed from the moon, they left a mirror there. To this day, scientists can point a laser and a telescope at the moon, and aim the laser at these mirrors, in order to accurately measure the distance between the earth and the moon! Another method that you can use is to measure the angles to the moon from two different cities on the surface of the earth at the same time. By using similar triangles, you can compute the distance to the moon. Mind you, this requires EXTREMELY accurate measurement techniques.
Given the ratio of the distance between the earth to the sun and the earth to the moon, calculations find an incredibly small number, almost 1/400. Multiplying by 400 meters gives a distance of just over 1.028 meters in this comparison.
The distance from the center of the Earth to the center of the moon is about 384,467 km. If you subtract from this distance the average radius of the Earth (6,378 km) and the average radius of the moon (1,738 km), you find 376,351 km.Convert the diameter of a strawberry seed, 2 millimeters, to kilometers: .000002 km. Now, divide the distance from the surface of the Earth to the surface of the moon by the diameter of a strawberry seed. The answer is: 188,175,500,000 strawberry seeds!
Moon phases. As the moon revolves around the earth on its tilted path, (search for diagrams to find out what happens with it tilted) the light from the sun hits the moon and reflects towards earth. But we see a different amount of light and darkness depending on where it is in the orbit. This causes us to see different shapes.

The rotation of the Earth causes us to see the moon differently. When the moon is between the Earth and the sun, there is no light reflecting from the moon, and that is when there is a new moon.
You would find this on the Earth's moon.
Sonar is a sound phenominon, it requires a liquid (water, air, etc) to work.
its a easy ques but hard to find
