Types of Volcanoes
Answer:
Shield volcanoes are formed by basaltic magma, regularly over a mantle crest, though the stratovolcanoes (now and then alluded to as composite volcanoes) are framed by andesitic/rhyolitic magma.
- Basaltic magma is regularly created by direct softening of the Earth's mantle, the locale of the Earth beneath the external outside layer. On mainlands, the mantle starts at profundities of 30 to 50 km. Shield volcanoes, like those that make up the Islands of Hawai'i, are made essentially out of basaltic.
- Basaltic magmas that structure the maritime outside layer of Earth are created in the asthenosphere at a profundity of around 70 kilometers. The basaltic magmas, mantle rocks situated at profundities from around 70 to 200 kilometers are accepted to exist at temperatures marginally over their dissolving point.
