Slow moving lavas tend to be more felsic because of their high silica content and faster moving lavas tend to be more mafic.

Magma is the wrong answer. Magma is the term used for molten rock that has not reached the Earth's surface.
Pahoehoe (pronounced "puh-hoi-hoi) lava is slow moving.
AA (pronouned "ah-ah") is fast moving.

Lava is molten rock. As it travels further from its central hot source (the vent of the volcano) it cools. As it cools the temperature of the lava falls below that required to keep it in a molten state, therefore it solidifies again - or freezes as you put it.
