Final answer:
Felsic and intermediate igneous rocks, such as rhyolite and granite, are commonly steep and formed from coarse-grained intrusions composed mostly of feldspar and quartz, with minor hornblende and biotite.
Step-by-step explanation:
Felsic and intermediate igneous rocks, such as rhyolite and granite, are commonly steep and formed from coarse-grained intrusions composed mostly of feldspar and quartz, with minor hornblende and biotite. They have a fine crystalline texture due to cooling of high-viscosity lava and are often light gray to pinkish to somewhat reddish in color. The statement that these rocks are constructed from felsic to intermediate rock is true.
