Nuclei of bonding atoms exchange electrons; the resulting ions are bonded together by the attractive forces between the negative and positive nucleons. Atoms of two different elements share electrons and protons; the resulting compound is bonded together by the strong, binding energy of shared protons. Nuclei of two different atoms share electrons, and the resulting compound is tightly bonded by the very strong, induced, electronuclear bonds. Atoms of different elements, having gained or lost electrons, form negative and positive ions that are bonded together by attractive forces between ions with opposite charges.

They contain iron and magnetite, are black in color, and they have metallic lusters. They are black to dark-green and contain iron and magnesium. They are mostly clear, colorless, and rich in the element calcium and magnesium. They contain magnetite and hematite and are rusty red. Question 19 of 30 Which one of the following is an abundant product of weathering? amphiboles feldspars clays halite Question 20 of 30 Granite is an example of a/an ______________ igneous rock. phaneritic vesicular aphanitic foliated Question 21 of 30 A magma cools for a long time beneath the Earth's surface and then flows in a volcanic eruption. A ______________ igneous rock will result. schistose polymorphic porphyritic composite Question 22 of 30 The intrusive rock ________ has the same chemical composition and mineralogy as the extrusive rock ____________. granite, rhyolite basalt, gabbro andesite, diorite pumice, obsidian Question 23 of 30 A rock that will float in water is obsidian gneiss tuff pumice Question 24 of 30 If the oceanic crust of the Earth cracks, the rocks below may _____. melt due to decompression shrink in volume instantly explode due to exposure not change in consistency Question 25 of 30 The presence of water causes _____. slowing of crystallization rocks to melt at lower temperatures porphyritic textures raising of rocks' melting temperatures Question 26 of 30 Bowen's Reaction Series indicates that amphibole and an intermediate composition plagioclase feldspar crystallize earlier from a cooling magma, while quartz and potassium feldspar crystallize later. If an igneous rock containing these four minerals is heated to a temperature at which melting begins, _____. all four minerals will melt at the same temperature the amphibole and plagioclase feldspar will start melting before the other minerals the quartz and potassium feldspar will start melting before the other minerals amphibole and quartz will melt first, then the feldspars Question 27 of 30 The incorporation of host rock into a magma is called _____. migmatism assimilation magmatic differentiation starving Question 28 of 30 Magmas that produce stratovolcanoes are _____. high in silica and viscous high in silica and fluid low in silica and viscous low in silica and fluid Question 29 of 30 The Hawaiian Islands are a chain of _____. stratovolcanoes lava domes shield volcanoes fissure flows Question 30 of 30 An igneous intrusion that resembles the filling in a layer cake is called a _____. sill dike stock batholiths
