The answer is lithosphere.
Stanley Miller's experiments showed a pre-cellular life could have begun with the formation of lipids, but it should be noted that this is not necessarily true.
The bond energy is defined as equal to the amount of energy given out when the bond is made (or absorbed when that the bond is broken).
So when a bond is made, and the system cools to its original energy, the amount of energy given out, -DeltaH, is more or less equal to the bond energy.
Noticed that minus sign. For a process that releases heat, DeltaH is negative.
Internet to the rescue
Hope this helps!
Horizontal or transverse or axial cut is if you cutting the object with the horizontal plane. The cut would look like ( -- ).
Vertical or longitudinal is cutting in the vertical plane. The cut would look like ( | )
