Detailed Solution

The given statement is True. Petroleum is mainly found in sedimentary strata.
1)      Petroleum relates to fluid hydrocarbons, including both gases and liquid crude oil. It occurs almost entirely within sedimentary rocks. Petroleum got rarely discovered in igneous or metamorphic rocks.
2)      Most minerals are found in sedimentary rocks in the form of beds or layers. They originated due to horizontal strata deposition, accumulation, and concentration. Coal and other types of iron ore occur due to prolonged exposure to high heat and pressure. Sedimentary rocks were generated due to the accumulation of minerals and organic materials. There are three types of sedimentary rocks: Clastic, Carbonate, and Evaporitic. Substances buried beneath the sedimentary rocks combine to form petroleum. Sandstone and limestone are excellent reservoir rocks for petroleum deposits to form.
