Question

Patterns of occurrence of stratovolcanoes and their composition Part A Are there any patterns you have noticed regarding where composite volcanoes (also known as stratovolcanoes) occur? What is the composition of the lava erupted by these types of volcanoes? What is the composition of the magma that intrudes the Earth undermeath composite volcanoes to form batholiths? Can this type of rock ever subduct? Lastly, combine these observations to make a statement about a major feature of the Earth's surface Hints Essay answers are limited to about 500 words (3800 c characters maximum, including spaces). 3800 Character(s) remaining

Explanation / Answer

Stratovolcanoes occurrence pattern : Stratovolcanoes are common in oceanic - continental convergent plate boundary where ocean since it is less dense than the continental area, slides inside the land or ocean - ocean convergent plate boundary and forms a Subduction zone. Due to sliding of the crust, water is released in the porous Basalt from hydrated minerals and heats the mantle lying in the layer above the sliding crust. This magma rises to the crust and stays in the volcano and erupts later.
