What are the five volcanic lend forms ? Cinder cones calderas, sheild volcanoes, flood basalt, and composite volcanoes. Volcanic activity occurs In three settings: Subduction boundaries Sea-floor spreading centers Hotspots What Is the difference between effusive and explosive eruptions? Effusive eruptions arm the relatively gentle ones that produce enormous volumes of lava annually on the sea floor and In places such as Hawai'l and Iceland. Basaltic rock low In silica (less than 50% silica) and rich In Iron and magnesium. Volcanic activity Inland from subduction zones produces the Infamous explosive volcanoes. Magma produced by the melting of subducted oceanic plate and other materials is thicker (more viscous) than magma that forms effusive volcanoes. It Is 50%-75% silica and high In aluminum

Explanation / Answer

13.What are the five volcanic landforms?

Cinder cones, calderas, shield volcanoes, flood basalt and composite volcanoes.

14. Volcanic activity occurs in three settings:

Subduction boundaries

Sea-floor spreading centers

Hotspots

15. What is the difference between effusive and explosive eruptions?

Effusive eruptions are the relatively gentle ones that produce enormous volumes of lava annually on the seafloors and in places such as Hawai'I and Iceland.

Basaltic rock low in silica(less than 50% silica) and rich in iron amd magnesium.

Volcanic activity Inland from subduction zones produces the infamous explosive volcanoes.

Magma produced by the melting of subducted oceanic plates and other materials is thicker (more viscous) than magma that forms effusive volcanoes.

It is 50% - 75% silica and high in aluminium.
