Periodically during severe pole shifts, land rises or drops, sometimes moving under the waves. This is caused quite naturally by moving plates, which adjust to being squeezed against each other or pulled apart. Suddenly submerged land can be the result of either dynamic. Likewise, land long under the sea can suddenly pop up, presenting gasping and dying sea life and deep muck that eventually dries to form new and very fertile soil. Continents pulled apart, as in the steadily widening St. Lawrence Seaway or African Rift, can cause land along the perimeter to rise, as the stretch over the curvature of the Earth has been removed, so that the natural buoyancy or shape of the land can take effect. Thus the land in the New England area of America is expected to lift somewhat when the St. Lawrence Seaway tears further apart. Continents pulled apart, as in the widening Atlantic rift, cause sinking land along the shores for several reasons:
Continents squeezed together invariably find one plate or the other acting as the loser, subducting or fracturing into pieces that slant at an angle to form new mountain ranges. For every adjustment where the continents or land are being wrenched apart, there is a collateral squeezing of plates elsewhere. On the Earth, this squeezing occurs along the Pacific Rim, with Japan and the Philippines, along with the whole western coast of the Americas, getting the brunt of this squeeze. This is often the case, and thus as a result of the coming pole shift, new land will emerge near Antarctica between the tip of Africa and South America due to pressure against the western coast of South America. Due to the strength of the Antarctic plate, this pressure will be relieved by allowing the Antarctic plate to ride over the bordering plates, thus creating new land.
Where this squeezing causes new land to rise is where plates fracture, freeing a portion of a plate to act on its own. Squeezing can force land under, to relieve the stress, but can also pop land up, so that it rides above another plate. What occurs when an overriding plate moves across or pushes against an underlying plate depends primarily on what the underlying plate presents. If the land is fairly flat, the overriding plate will go for a ride, with anything on the underlying plate scraped along or crushed underneath. If the land is hilly or mountainous itself, the hills and mountains will be compressed and crumpled, creating a situation where rocks and earth are flying about, tumbling and spewing.
