What IS A VOLCANO?
... Lava occurs in active volcano while magma occurs in an inactive one. At the core of the earth is hot molten rock, magma. The molten rocks erupt through a volcano and come out as lava. The temperature of magma is extremely high while that of lava are lower as it cools down when it comes out under the ...

Shield volcano
A shield volcano is a type of volcano usually built almost entirely of fluid magmaflows. They are named for their large size and low profile, resembling a warrior's shield lying on the ground. This is caused by the highly fluid lava they erupt, which travels farther than lava erupted from stratovolcanoes. This results in the steady accumulation of broad sheets of lava, building up the shield volcano's distinctive form. Shield volcanoes contain low-viscosity magma, which gives them flowing mafic lava.
