A
  1. Shield volcano

2. Stratovolcano

2
Q

Shield volcano and stratovolcano are different in their physical appearance.

E.g. Shield volcano has wider base, while the base of stratovolcano is not as wide.

This is due to ____

A

SILICA content.

Shield volcano – LOWER in silica content, hence less viscous – lava can flow across a longer distance before cooling.

Stratovolcano – HIGHER in silica content, more viscous – lava flows across a shorter distance

3
Q

Which type of volcano has steeper slopes and taller in height?

A

Stratovolcano

4
Q

Which type of volcano has more violent eruption and why?

A

Stratovolcano because HIGH SILICA lava traps more air.
