Seafloor spreading is occurring at the boundary
between the
A. African plate and Antarctic plate
B. Nazca plate and South American plate
C. China plats and Philippine plate
D. Avstralian plate and Eurasian plate

Answer:

A

Explanation:

The african and antarctic boundry is a divergent plate so there seafloor spreading would occur.

Seafloor spreading is occurring at the boundary between the African plate and the Antarctic plate. The correct option is A.  At divergent plate boundaries, seafloor spreading takes place. The mantle's convection currents generate heat that makes the crust more plastic and less dense as tectonic plates slowly drift apart from one another.

The formation of new oceanic lithosphere at divergent plate boundaries and its removal are both mediated by seafloor spreading. The scientific revolution known as plate tectonics was sparked by the seafloor spreading hypothesis, which is regarded as one of the most significant paradigm shifts in the history of Earth sciences.

Since that time, Antarctica, South Africa, and India have separated from Africa. Three mid-ocean ridges diverge along the eastern, southern, and the majority of the western sides of the African plate as a result. The South Pacific Ocean's seafloor is home to the Pacific-Antarctic Ridge (PAR), a divergent tectonic plate boundary that divides the Pacific Plate from the Antarctic Plate.

Thus, the ideal selection is option A.
