Dikes: Cut across existing strata (usually) vertically
Sills: Intruded between and parallel to existing strata
Laccolith: Lens-shaped, causes uplift in the shape of a dome

yessir. I believe there's also batholiths which are formed by magma intruding into a body but doesn't reach the surface?

Explain the difference between mafic and felsic minerals. How are mafic and felsic minerals formed?

Explain the difference between mafic and felsic minerals. How are mafic and felsic minerals formed?

Felsic and Mafic rocks are types of igneous rocks, meaning they are formed by lava/magma cooling. Mafic (wordsmash of magnesium and ferric) rocks/minerals are generally heavier, have less Silica, and contain Magnesium and Iron, and Felsic (wordsmash of feldspar and silica) rocks/minerals are lighter in weight, have more Silica, and contain the elements for Feldspar (Idon'trememberoffthetopofmyhead) and Quartz (SiO2).

Yep, your turn! (Also I said minerals in the question, but minor detail.)
