Intrusive Volcanic Features and Processes

The video tutorial by Professor Courter explains volcanism, focusing on intrusive volcanism where magma remains inside the Earth. It covers various intrusive volcanic features such as batholiths, stocks, pipes, sills, dikes, and laccoliths. Each feature is described in terms of its formation, characteristics, and examples, like the Sierra Nevada batholith. The tutorial emphasizes understanding these features' roles in geology.
