Yes, in context, it can refer to the characteristic rock type of a specific layer or unit, e.g., 'The lithology here is primarily limestone.'
Yes, it has critical applications in the petroleum industry (reservoir rock identification), mining, hydrogeology, civil engineering (foundation assessment), and environmental science.
Through practical field work and hands-on examination of rock samples (hand specimens) alongside studying geological maps and well logs, as it is a fundamentally descriptive science.
