Answer:
Basaltic magma -- SiO2 45-55 wt%, high in Fe, Mg, Ca, low in K, Na
Andesitic magma -- SiO2 55-65 wt%, intermediate. in Fe, Mg, Ca, Na, K
Rhyolitic magma -- SiO2 65-75%, low in Fe, Mg, Ca, high in K, Na
Explanation:
6.666 because the formula of time is distance by speed
Answer: Clay and quartz
Explanation:Granite is a type of igneous rock that is present for injecting magma into the crust of Earth and then cools down. When weathering process occurs then there is breakage in the rocks at the Earth’s surface into other substances such as sediments, etc.
So, when there is the weathering in the granite the quartz will be same residual minerals because they have a resistance to weathering and biotite will have a hydrolysis process for the formation of clay.
