Answer:
B) basalts lava
Step-by-step explanation:
Basaltic lava can flow from fissures, forming large amounts of lava. This can create a large area of lava, which can be a hazard to people and property.
Lava flows from fissures because molten rock is less dense than solid rock. When the pressure on the molten rock becomes too great, it flows out of the fissures.
