No, it is not accurate to say that the Earth is expanding or that gravity is increasing. The Earth's size has remained relatively constant over geologically significant timescales. While there are various geological processes that cause the Earth's surface to shift, such as plate tectonics, these movements do not result in a net increase in the Earth's size.
As for gravity, it is a fundamental force that depends on the mass and distance between objects. The force of gravity between two objects is determined by their masses and the distance between their centers. Gravity on Earth is primarily influenced by the mass of the Earth itself. While the distribution of mass within the Earth can cause slight variations in the strength of gravity at different locations on its surface, there is no evidence to suggest a significant and ongoing increase in gravity on Earth.
It's important to note that scientific understanding is always subject to refinement as new evidence and theories emerge. However, based on our current knowledge, the idea that the Earth is expanding or that gravity is increasing is not supported by scientific consensus or empirical observations.
