Why is the Earth not getting larger if the sea floor is slowly spreading?</h2>
Mainly due to the Atlantic experiencing seabed expansion. The sea bottom is subducting, or moving underground, in the Pacific. This is how the Earth's tectonic plates and geological activities function. The top side of the mantle travels to the bottom at one end and to the top at the other, similar to a conveyor belt. This explains why there are volcanoes, why continents drift, and why our planet's surface is continually changing over the span of millions of years.
Therefore, the planet is not getting bigger because its surface is constantly recycling itself.
