- Summary
- There are two kinds of volcanoes: one kind with violent eruptions producing steep slopes and the other kind with voluminous lava flows producing gentle slopes
The character of volcanic eruptions are largely controlled by the viscosity of the magma. Indeed, low -viscosity magma:
- flow more easily than high viscosity magma
- allow gases to escape easily whereas gas pressures can build up in high viscosity magmas.
- Learning objectives
- To distinguish effusive eruption from explosive eruption.
- To name the parts of a volcano.
- To describe the sequence of an eruption.
