Question
By what two properties are ail rocks classified? Explain the difference between granite and rhyolite. In your explanation, include any differences and similarities In their textures, mineral compositions, and processes of formation. In the lab, you learned how cooling rate affects the texture of Igneous rocks. Describe a situation in which a porphyritic texture might develop In an igneous rock. Rivers and stream systems tend to originate in mountainous areas, where they erode into the surrounding rock and transport large volumes of sediment. The velocity of water in rivers is influenced by a variety of factors, one of which is the volume of water being transported. The volume of water in a stream fluctuates depending upon the amount of precipitation, melt, and runoff it receives. Therefore, a stream's velocity (and, thus, capacity to carry large sediments) varies over time. Based on this information, along with your observations from lab, which sedimentary rock in your kit was likely formed in a fluvial (river or stream) environment?Explanation / Answer
1)there are several ways to classify the rocks, rocks can be classified according to their genesis. rocks which are formed from magma are called igneous. rocks which are formed by the process of weathering and erosion of igneous rocks called sedimentary rocks, and rocks which are formed by the alteration of pre existing igneous and sedimentary rocks are called metamorphic rocks.
rocks can be classified according to their grain size such as coarse grained rocks and fine grained rocks, and the other is based on mineralogy whether it is felsic or mafic etc
2) granite and rhyolite have the same mineralogical compositions but their texture is different . granite is formed as a plutonic rock so it has coarse grained texture where as rhyolite is formed as a volcanic rock so it has fine grained texture
