What are the main natural resources of North Africa?
oil bp is there
Why is helium safer than hydrogen for airships?
Helium, but there are more limited supplies of it. At the time of the Hindenburg, the US was the sole source with all of it coming from Texas oil fields mixed in with the natural gas. It was there because of the combination of deep Uranium Ore deposits and Salt Domes, Uranium decay alphas captured electrons becoming Helium then got caught in the salt domes with the natural gas on top of the oil. The US refused to sell Helium, a strategic resource to Nazi Germany. Helium is a Nobel Gas thus inert, Hydrogen ignites and burns easily.
Why is there any Helium on earth given it evaporates into space and does not react with anything?
Helium is created by the radioactive decay of certain elements in the earth's crust. ---- Oil wells is a common source of helium. Some people worry that we may have future shortages of helium as the supplies in wells is used/released.

What are the five resources in the US?

Is oil a compressible liquid?
No, because it is not compund substance
Why can oil not be compressed?
Actually, oil can be slightly compressible. As an oil field is produced and the pressure declines, the oil within the oil deposit will expand. Most liquids, like water, are slightly compressible. This is an important property in the evaluation of oil fields and well testing. See link.
Why is water not used instead of oil in hydraulic jack?
water is compressible
What is the primary reason to use hydraulics instead of pneumatics?
oil is slightly compressible 0.5 % at 70 bar. but air is compressible. so to get the required pressure pneumatics require more energy source than hydraulics also there are some limitations for pneumatics in terms of force.
Why does kerosene oil catch fire faster than wood?
This is because the specific heat capacity of the wood is more than the kerosene oil. So, the wood takes time to burn but burns for longer period than the kerosene oil.
What goods are carried by ships?
Oil, wood, china goodies, and more.
What make petroleum oil suitable as a hydraulic fluid?
Oil transmits power readily because it is minimally compressible, Lubrication abilities and the cooling properties.
