- 1rock with two dominant grain sizes is calledporphyritic
- 2difference between a dike and a silldike cuts up across multiple layers, sill sits like a shelf between layers
- 3magma is solids, liquids, and gasestrue
- 4minerals that are first to melt in magma/lavafelsic
- 5this factor notably affects grain sizescooling rate
- 6igneous rocks form fromcooling of magmas/lavas
- 7where does decompression melting occurmid ocean ridges, hot spots, continental rifts
- 8Bowen's reaction series describedorder of crystallization of minerals in a cooling body (what cools first)
- 9NOT common in igneous rockscarbon
- 10accurate depiction of flux melting?water and other volatiles lower the melting point of mantle rocks which can cause them to melt
- 11in what geological setting do you NOT find igneous rocktransform boundaries
- 12igneous rocks with a glassy texture do nothave any mineral crystals
- 13igneous rocks are typically composed of only one mineral and are typically felsicFALSE
- 14what causes magma to have a high viscosity (Thicc)high silica, low temperature, low gases
- 15highest silica content to lowestfelsic, intermediate, mafic, ultramafic
