How does the type of magma erupted influence the morphology of a volcano? For example, whether it forms as a low, broad shield or a tall, steep volcano, like ones in the Cascades. (please i need an serious answer for me to manage ideas for my proposal) Thankyouu, hoping someone can help me<3

Answer:
As the silica content increases, these rock types generally become more viscous; as the magmatic gas content increases, they become more explosive. Other physical properties are, however, important in determining the character of lava flows. For example, hot basaltic lava produces flows with smooth to ropy surfaces.
Explanation:
Shield volcanoes have the following characteristics:
Basaltic magma, which is high in temperature, very low on silica and with low gas content. ...
Basic lava, which is non-acidic and very runny.
Gentle sides as the lava flows for long distances before it solidifies.
No layers, as the volcano just consists of lava
