Magma is pushing the plates up and apart from one another.
Explicación
## Step 1The question is asking why underwater mountains, also known as seamounts, are so tall. The answer to this question lies in the theory of plate tectonics.## Step 2According to the theory of plate tectonics, the Earth's crust is divided into several large and small plates that float on the semi-fluid asthenosphere beneath them. These plates are constantly moving, and when they move apart, magma from the mantle rises to fill the gap.## Step 3This process is known as seafloor spreading. As the magma rises and cools, it forms new crust, which adds to the height of the seamount. Over time, this process can lead to the formation of large underwater mountain ranges.## Step 4The statement that the ocean is less dense there is not accurate. The density of the ocean varies, but it is not the primary reason for the formation of underwater mountains.
