I didn't really understand so I looked it up and I couldn't figure out how to word it differently from the website because the answer was right. I guess that is cheating, sorry.#1 is almost directly copied from this, but correct, your turn.General knowledge questions 1. What is the difference between continuous and discontinuous when it comes to the Bowen's Reaction Series? 2. Define isometric. 3. What is the hardness of your fingernail? 4. What are elements commonly found in Mafic Igneous rocks? Felsic? 5. Why are properties like streak and density unorthodox ways to identify rocks?1. Continuous means the evolution of plagioclase feldspar from being calcium-rich to sodium-rich. Discontinuous means the formation of mafic minerals like olivine, pyroxene, biotite mica, and amphibole 2. Isometric is the cubic crystal system. 3. 2.5 4. Mafic= iron (Fe) and magnesium (Mg) Felsic= aluminum (Al) and silicon (Si) 5. Properties like streak and density aren't usually used to classify rocks because of how common they are between each kind of rock. Instead, we use texture to classify them because each rock has a different texture.
Also here are new questions
