Electric vs. Gas Heat. In a shift from the past, it is now less expensive to heat with electricity in Indiana than with natural gas. 1  The cost of gas has risen an average of 8% a year over the last 10 years, a huge increase.2  Gas heating will cost Central Indiana residents more than $1,800 this winter to heat a 1,800 sq. ft. home.lectric vs. Gas Heat.

Planetary boundary layer. The planetary boundary layer (PBL) is also known as the atmospheric boundary layer (ABL). It is the lowest part of the atmosphere and its behavior is directly influenced by its contact with the ground. It responds to surface forcings in a timescale of an hour or less.
The International Space Station orbits Earth in this layer. mesopauseâthe boundary between the mesosphere and the thermosphere; the coldest place on Earth. mesosphereâthe layer in which most meteors burn up after entering Earthâs atmosphere and before reaching Earthâs surface. stratopauseâthe boundary between the mesophere and the stratosphere. stratosphereâcontains the ozone layer; the layer where volcanic gases can affect the climate. tropopauseâthe boundary between the stratosphere and troposphere. troposphereâthe layer closest to Earthâs surface in which all weather occurs.
