The minerals that form when magma crystallizes slowly deep underground areGroup of answer choicesvisible without a microscopeglassyvisible with a microscope only

If a magma that is rich in Silicon and Aluminum cools over thousands of years underground, it forms Granite. If it cools quickly when it erupts from a volcano, it forms Rhyolite.If a magma that is rich in Iron and Magnesium cools over thousands of years underground, it forms Gabbro (which is sold as "black granite" at home improvement stores). If it erupts from a volcano, it also forms a black rock, but because it cools quickly, the crystals can only be seen under the microscope/ This rock is  _________Although _________ not common on continents, this rock is the most common rock on Earth's surface, because it forms the ocean floor. It is also the rock that makes up the Hawaiian islands, famous for their beautiful volcanoes and river-like lava flows.Group of answer choicesobsidiangranitebasaltpumice
