What features form as an oceanic plate moves across a hot spot?

Islands and volcanoes.

Explanation:

The oceanic plate reacting with the hot magma being released causes a mass of solid rock to form. This eventually builds up and results in either a volcano or another mass of land.

Volcano forms as an oceanic plate moves across a hot spot.

Explanation:

When lava is poured out from the crack which appears in the floors of the ocean, this leads to the formation of the new mountains. When magma comes out of the crust of the surface and reaches on the top at the surface.

This leads to the formation of a volcano from the hot spot which is a location on the surface of earth from where the heat comes up from the deep inside the earth melting the rocks and then this melt comes up from the cracks and form volcanoes.
