Summary:
Essential Question:
Location of Crystallization (Where Igneous rocks are formed)
A. Igneous rocks formed ______________ from Magma are called
______________ or ______________ rocks.
B. Igneous rocks formed ______________ from Lava are called
______________or ______________ rocks.
Texture or Crystal Size
The ______________ magma or lava cools, the ______________ the size of the crystals
in the solidified material will be.
A. When Magma cools ______________ underground, ______________ crystals
have time to form. Therefore, igneous rocks with large crystals are most likely
______________.
B. When Lava cools ______________ above ground, crystals have a limited time to
form. Therefore, Igneous rocks with ______________ or ______________
crystals are most likely ______________.

A. High Silica content causes Felsic Magma to be ______________ and
______________ flowing.
B. Low Silica content causes Mafic Magma to be ______________ and
______________ flowing.
