Does the moon determine the tides because of the gravity between earth and moon?

yes.


What can determine moon phase?

The position of the earth and moon on their orbit around the sun, determines how much and what area of the moon is lit by sunlight. The moon's phases are what we can view from the earth.

How are moon rocks used to determine the age of the Earth?

The oldest moon rocks are actually older than the oldest Earth rocks. The moon formed from accreted material that resulted from a collision between Earth and a Mars sized protoplanet. Both the Earth and the moon were molten for a period after the collision. Because of the moon's smaller size, it's surface cooled very quickly compared to the Earth. The solidified magma (rock) that formed the moon's crust has been dated at roughly 4.4 billion years of age. Even though no Earth rock has been found to date this old, we can still reasonably assume that the Earth is at least that old due to the fact that the moon is formed from accreted material from the previously mentioned collision.


What basis do evolutionists use to determine the world is 4.5 billion years old?

Isotope dating from rocks is the main method that is used. Zircon crystals that formed on Earth have been dataed to over 4 billions years old. Dating has also been done on rocks fromt he moon, which formed shortly after earth did, to nearly 4.6 billion years.


Why moon tiny?

In order for the moon to have been captured by the earth, it has to be smaller than the earth. If it were bigger, it would have pulled the earth into its orbit, making the earth the moon.


Determine the weight of a person on the Moon whose weight on the Earth is 183 lb?

To calculate the weight of a person on the Moon, we need to divide their weight on Earth by 6. This means that a person weighing 183 lb on Earth would weigh approximately 30.5 lb on the Moon. This calculation is based on the Moon's gravity being about 1/6th that of Earth's.


Who has been to earth's moon?

Astronauts.


When will the earth impact the moon?

That event hasn't been placed on the schedule, and as far as astronomers have been able to determine,it doesn't appear to be coming about as the result of any natural causes either.


Why do you think that the Earth having a greater mass would determine that the Moon orbits the Earth?

Since the Earth is so much larger, it has a greater gravitational pull. The moon orbits the Earth because of this pull.
