The document consists of questions related to geology and mineral properties, specifically focusing on the melting points of minerals, volcanic processes, and crystallization. It includes true/false questions on concepts like lava, rock geotherm, fractional crystallization, and Peter's reaction series. The content appears to be aimed at testing knowledge of volcanic activity and mineral formation.

1. Which of the following minerals melts the easiest? olivine amphibole quartz K-Feldspar.
Question 10 Fragmented material that sprayed out of a volcano and landed on the ground or sea
floor in solid form is called lava. True False The resistance of material to flow is the rock's
geotherm. True False Question 12 The process by which a magma becomes progressively more
silicic as it cools, because early-formed crystals settle out is fractional crystallization. True False
A fast-moving avalanche that occurs when hot volcanic ash and debris mix with air and flow
down the side of a volcano is called a fissure eruption. True False Question 14 2 pts The
sequence in which different silicate minerals crystallize during the progressive cooling of a melt
is Peter's reaction series. True False
