The first one would Be Divergent, and the Second One would be, Ridges
At a boundary, plates move away from each other as magma pushes them from below. When this change happens beneath the ocean floor, hot magma rises to the crust's surface, cracks develop in the ocean floor, and the magma pushes up and out to form mid-ocean ridges. Mid-ocean ridges or spreading centers are fault lines where two tectonic plates are moving away from each other.
"When located beneath the ocean, these plumes, also known as hot spots, push magma onto the seafloor. "These volcanic mounds can grow into volcanic islands over millions of years of activity. Transfer of Heat Magma can also be created when hot, liquid rock intrudes into Earth's cold crust.
"A tectonic plate (also called lithospheric plate) is a massive, irregularly shaped slab of solid rock, generally composed of both continental and oceanic lithosphere. Plate size can vary greatly, from a few hundred to thousands of kilometers across; the Pacific and Antarctic Plates are among the largest."
