The rising magma that can result from this type of plate movement may produce volcanic islands. Therefore, option G, volcanic islands, is the most appropriate choice.
What is volcanic island?
When some kinds of plates move, like when they spread apart or when there is a lot of heat coming up from inside the Earth, hot liquid rock can come up to the surface and make new islands.
Volcanic islands are usually made by volcanoes that happen where tectonic plates are moving apart or above hot spots. Divergent plate boundaries happen when big pieces of the Earth's crust move away from each other. This lets hot, melted rock come up and make new crust. Hotspots are where molten rock rises from below the Earth's surface, causing volcanoes to form as the Earth's crust moves over them.
Different kinds of magma come out of volcanoes, making different types of islands when they cool down. Some islands are made by a type of lava called basaltic magma. This lava is runny and usually causes slow and gentle eruptions. Different islands can be created by thicker and stickier magmas, like andesitic or rhyolitic magma. This can cause more powerful and explosive volcanic eruptions.
