Plate tectonic induced changes in the sea level could increase the total percentage of land area upto 40% or decrease it to as low as 17%
<h3>What are Tectonic plates?</h3>
Plate tectonics, whose name derives from the Late Latin tectonicus and the Ancient Greek letter v, which means "pertaining to building," According to the widely accepted scientific idea , the Earth's lithosphere is made up of many major tectonic plates that have been gently shifting for nearly 3.4 billion years
The model is based on the idea of continental drift, which was created in the early 20th century. After seafloor spreading was confirmed in the mid- to late 1960s, plate tectonics became largely accepted by geoscientists.

When plants are allowed to self-fertilize generation after generation, the exact same physical traits appears without any change. Such plants are called pure line or true-breeding. For example, tall plants always produce tall plants and true-breeding dwarf plants always produce dwarf plants on selfing.
