Which resource is abundant in Oklahoma?

Oklahoma is particularly well-known for its significant oil reserves, making oil the abundant resource in the state. The discovery of oil in Oklahoma in the early 20th century initiated a major economic transformation and development within the region. Oil production has historically played a crucial role in shaping Oklahoma's economy, culture, and demographics. The East Central region, in particular, is part of the oil-rich area known as the Mid-Continent Oil Province, which contributed to Oklahoma being one of the leading oil-producing states in the nation.

While coal is also present in Oklahoma, especially in the southeastern region, it does not match the level of production and economic impact that oil has had. Copper and tin are not notable resources found in abundance within the state, further emphasizing oil as the standout resource in Oklahoma's geological wealth.
