Answer:

In general, eruptions can be categorized as either effusive or explosive. Effusive eruptions involve the outpouring of basaltic magma that is relatively low in viscosity and in gas content. Explosive eruptions generally involve magma that is more viscous and has a higher gas content.

There are two types of eruptions in terms of activity, explosive eruptions and effusive eruptions.

Explanation:

• Explosive eruptions are characterized by gas-driven explosions that propels magma and tephra.
• Effusive eruptions, meanwhile, are characterized by the outpouring of lava without significant explosive eruption.
