Normal atmospheric pressure at sea level is around 14.7 psi.
Changes in atmospheric pressure can affect weather patterns and can also impact drilling operations in oil and gas industry.
Sedimentary rock is formed from the accumulation of sediment or organic materials over time.
It is one of the three main types of rock, along with igneous and metamorphic.
Examples include sandstone, limestone, and shale.
They often contain fossils and can provide information about past environments and climates.
They can be formed through processes such as erosion, deposition, and compaction.
They are typically found near ...
Igneous rock is formed from cooled and solidified magma or lava.
Formed through volcanic activity
Can be intrusive or extrusive
Examples include granite, basalt, and pumice
