As Snail is a land species, they for about 2-3 years, based on there calcium carbonate shells it can be concluded that they form in tropics.
Explanation:
When looking at the slabs or the plate from both the clockwise and counterclockwise, spiraled snails fossils are usually in the spiral forms and the bedrocks that may have collected their imprints from the sediments deposited in the geologic formation of the earth.
The slabs of rock are hence evidence of the tropical climates and their creation is a due result of their shells that were deposited in the large tract of rocks when the uplifting of landmasses and the volcanic events take place.
Geologists use carbon-14 dating technology of the rocks estimate that their formation which hence is impacted due to the climatic region dominating the tropical oceans and lands is suited to the formation of these small creatures that their existence on the calcium carbonates creates this evidence.
This is known as orographic rainfall and after this process, the air is dry because it has lost most of its moisture over the Atlas Mountains. ... This second extreme rain shadow effect partially explains the extreme aridity of the eastern Sahara Desert, which is the driest and the sunniest place on the planet.
I think that it is hotspots because hotspots are places with a lot of volcanoes and has nothing to do with earthquakes. I am sorry if it is wrong. Hope this answers your question.
