Yes, earthquakes and volcanoes are important for the formation of island chains. Volcanic activity creates new land through the eruption of lava and ash, leading to the formation of islands.

What is the major process of surface rock formation on volcanoes?

The major process of surface rock formation on volcanoes is volcanic eruptions. When molten rock (magma) from the Earth's mantle reaches the surface, it solidifies to form igneous rocks like basalt or rhyolite. Over time, repeated eruptions build up layers of volcanic rocks that contribute to the formation of the volcano.

What do volcanoes have to do with rocks?

Volcanoes form when molten rock, called magma, rises to the surface of the Earth and erupts. This magma can be made up of different types of rocks, such as basalt or andesite. As the magma cools and solidifies, it forms igneous rocks like basalt, rhyolite, or obsidian, which are commonly found around volcanic areas.
