The earliest geochronological age, or geological age. First of six main divisions in ascending order in the upper cretaceous series representing rocks deposited worldwide during the Cenomanian age which occurred 99.6 to 93.5 million of years ago during the Cretaceous period. Rocks of the Cenomian stage overlie those of the Albian stage and underlie rocks of the Turonian. Rocks from this period are very abundant in Israel, in the Galilee, in the North of the Negev in proximity to the Dead Sea and in the Eilot region and include marine sedimentary rocks which is proof that these regions were covered in water at a certain period.

Unit of kinematic viscosity equal to 1/100 stoke

Unit of viscosity. It is the amount of force needed to move a layer of liquid in relation to another liquid. Equal to 1/100 of a poise

65 million years ago to today

544 to 505 million years ago

The standard unit for measuring a quantity of thermal energy. One Btu equals the amount of thermal energy required to raise the temperature of one pound of water one degree Fahrenheit and is exactly defined as equal to 1,055.05585262 joule, rounded to 1,055.056 joule, for most applications. (A joule is equal to one watt-second.)

Widely used for onshore natural gas pipelines
