Question

Rhyolite lava:

a) Tends to erupt exposively
b) Has less silica than basaltic lava
c) May flow for many tens or hundreds of kilometers from a vent or volcano
d) Commonly exhibits pahoehoe textures

Answer 1

Rhyolite lava is a felsic, extrusive igneous rock that tends to erupt explosively and can flow for long distances. It commonly exhibits pahoehoe textures.

Step-by-step explanation:

Rhyolite lava is a felsic, extrusive igneous rock that tends to erupt explosively. It has the same chemistry and mineralogy as granite, but is very finely crystalline due to the cooling of high-viscosity lava. Rhyolite lavas are highly viscous and often flow for many tens or hundreds of kilometers from a vent or volcano. While rhyolite can exhibit various textures, it commonly exhibits pahoehoe textures, which are smooth and rope-like.
