Helium is an inert gas used in lighter-than-air crafts like blimps because
it is nonflammable. It is formed deep underground over millions of
years as a by-product of the formation of natural gas. Almost all of the
world's helium is found in deep deposits of natural gas within 250 miles
of Amarillo, Texas. Helium can be considered what type of natural
resource? SC. G.2.3.1
A. a fossil fuel
B. a renewable resource
C. a part of the carbon cycle
D. a nonrenewable resource
