result in less violent eruptions than felsic to intermediate magmas.

Explanation:

Mafic magma results in less violent eruptions than felsic to intermediate magma.

They are predominantly made up of a high level of magnesium and iron in their composition.

The have very low silica content in their composition. They are usually less viscous due to their low silica proportion. They produce less violent eruptions and allows gases to move and escape easily through them. Felsic magma on the other hand produce very violent eruptions. The have a high silica content and often traps gases within them.
