If new seafloor is being created how does the earth stay the same size?

Because it only gets larger in one direction by getting smaller in another. In the case of ocean ridges, the 'other place' is wherever the crust has subducted into the natle at a plate boundary.

Why is Earth not getting larger if the seafloor is spreading?
Subduction and folding.The seafloor ,may be "spreading" in the center but that doesn't necessarily mean it's getting bigger; at the edges it may be slipping underneath a continental plate (subduction) or piling up on itself to form mountains (folding).
What does the earth's crust have in common with a conveyor belt?
simple! they both are constantly in motion. A conveyor belt moves in one direction while carrying something. In this same way, the seafloor (which is a part of Earth's crust) is spreading while carrying new lithosphere.
What was the second animal to appear on earth?
As far as humans know, the first human being was god, who created Adam and eve. Adam and Eve had 2 kids. Since Adam and eve were created and not technically born and they were created at the same time, their children were evidently the 1st and 2nd people on earth.
Why do people think the earth is square?
Because we did not know earth was an oblate spheroid. Ignorance: same reason some people think an invisible superhero created it.
Does earth's crust have the same density?
Density will vary from place to place with ocean crust being denser than continental crust.

Why is it written in the bible in the being god created heaven and earth and another entry is written lord god made earth and heaven?
they both mean the same thing and you spelled it wrong. in the being God made the heavens and the earth, you put that. its supposed to be in the beginning God made the heavens and the earth.
Why must the production and destruction of the lithosphere be going on at the same rate?
New lithosphere is constantly being produced at the oceanic ridges. Lithosphere is consumed at the subduction zones. A balance is maintained because older, denser proportions of oceanic lithosphere descend into the mantle at a rate equal to seafloor production.

Are there any planets older then earth?
No. Planets in solar system were created same time as earth was created. -The memory Guru of India
Does seafloor displaces more of the mantle that the same thickness of the continental crust?
Yes
Why does the Earth's size remains the same despite of what is happening at the mid-oceanic ridge?
An equal amount of oceanic crust is being subducted at the convergent plate boundaries as is being created at the mid-oceanic ridge.
How does seafloor spreading help scientists explain continental drift?
If one can prove that the sea floor spreads out from the mid oceanic ridges, then logically the continents must be moving apart to accommodate the spreading. Conversely there must also be places where sea floor is being destroyed if the Earth is to stay the same size.
When was Lullaby of the Earth created?
Lullaby of the Earth was created in 1970 by Japanese composer Isao Tomita. The piece was inspired by Japanese poet Kenji Miyazawa's poem of the same name.
Why do astronomer believe they can learn about the early earth by studying comets?
Because comets were created about the same time as the Earth.
Why did astronauts travel to the moon?
To investigate and to see if tyhe moon really did break off the Earth or was it created at the same time the Earth was created; meaning did God create it.
