Answer to Question 1

Volcanism also builds material up, including at the volcanoes themselves and at lava flows. Large
islands in the ocean, such as Hawaii, are constructed entirely of material from volcanic eruptions. New
seafloor is created by volcanic processes. Also, the early atmosphere and oceans were filled with gases
that came from the interior of the Earth, through the mechanism of volcanism

Answer to Question 2

Volcanism is the process by which magma rises through Earth's crust and issues forth at the surface as
lava flows and/or pyroclastic materials and gases. Volcanism is responsible for all extrusive rocks,
such as basalt, tuff, and obsidian.
