Essentially, yes. The earth accumulates cosmic dust, meteorites and the occasional comet, but not at a rate significant enough to appreciably change the earth's circumference. The sinking of heavy rock, such as caused by the recent 8.8 magnitude earthquake in Chile also does not measureably change the earth's circumference. Some scientists estimated earth's rotational velocity may have accelerated as much as a millionth of a second per day from that earthquake, however.

The motion of the continental plates about earth's surface does not appreciably affect earth's circumference either. These plates move about on a half billion year cycle known as the Wilson Cycle.

How to calculate the circumference of the Earth?

To calculate the circumference of the Earth, you can use the formula C 2r, where C is the circumference, is a constant (approximately 3.14159), and r is the radius of the Earth. The average radius of the Earth is about 6,371 kilometers. Plug this value into the formula to find the circumference.


Does the total amount of water on earth remain fairly constant or change regularly?

fairly constant


How would the value of g and G be affected if mass of the earth becomes four times?

G would remain the same, it's the gravitational constant which is the same everywhere in the universe. g would increase by 4 times, assuming that the radius of the earth didn't increase.


How angular momentum of the earth remain constant?

As there is no external torque acting on it, its angular momentum remains constant. This is according to the law of conservation of angular momentum


What type of movement does a surface wave have?

How many times larger is the earth's circumference's than Luna?

The Earth is 3.64 times larger than Moon's Circumference. (Earth's Circumference) 39,843 divide by (Moon's Circumference) 10,921=3.64


Why are longitudes equal in length?

Every line of constant longitude joins the north and south poles. Therefore the length of every line of constant longitude is one half of the earth's polar circumference.


How does the water cycle keep the earth's water supply constant?

earth remain Fly constrant over time though this does not mean that precipitation will increase


Why the formula of circumference of circle always constant?

Because:- circumference/diameter = pi and when the formula is rearranged circumference = pi*diameter


Are longitudes same length?

Every meridian of constant longitude joins the Earth's north and south poles, so the length of each meridian is 1/2 of the Earth's polar circumference.


Can you replace a formula with its function so it can remain constant?

No but if you replace a constant with a function it will remain a formula
