Introduction to Petrology and Igneous Rocks

What is the main focus of petrology?

Which type of igneous rock forms with large mineral grains due to slow cooling beneath the Earth's surface?

What process forms sedimentary rocks?

Which type of rock results from the transformation of existing rocks due to heat, pressure, or chemical changes?

What causes extrusive or volcanic rocks to have fine-grained mineral grains?

Which type of igneous rock contains high amounts of silica and includes granite and rhyolite?

Where is basalt commonly found as an igneous rock?

What process causes magma to cool and solidify, leading to the crystallization of minerals within it?

Which type of igneous rock consists mainly of ferromagnesian minerals and is high in iron and magnesium?
