Is it true Andesitic rock is an igneous rock with a composition in between that of basaltic and granitic igneous rock.?

Yes, andesitic rock is indeed an igneous rock that has a composition situated between basaltic and granitic rocks. It typically contains a moderate amount of silica, ranging from about 57% to 63%, which gives it characteristics that are intermediate between the two. Andesitic rocks are commonly found in volcanic arcs and are often associated with subduction zones.

What are the three families of igneous rocks?

The three families of igneous rocks are basaltic (mafic), andesitic (intermediate), and granitic (felsic). These families are classified based on their silica content and mineral composition, which in turn influence their color, density, and overall characteristics.

Which igneous rock forms when basaltic lava and when basaltic magma hardens?

Basalt forms when basaltic lava cools and solidifies at or near the Earth's surface. When basaltic magma cools and solidifies below the surface, it can form a type of igneous rock known as gabbro. Both basalt and gabbro are composed primarily of plagioclase feldspar and pyroxene, but they differ in their formation and texture due to their cooling environments.
