Answer:
The correct answer is - energy.
Explanation:
Transform fault boundaries are the plates that move one past another without causing damage or destruction to the crust, these form when two plates move in the opposite direction or in the same direction.
At transform fault boundaries plates moving in opposite directions have a tendency to get stuck which leads to a high amount of energy formation. There is no damage or destruction that takes place nothing occurs but earthquakes along with the fault.

Loni makes a diagram to help organize what she has learned about the gas laws.
Which label belongs in the region marked X?
involves changes in temperature
has a constant volume
shows an inversely proportional relationship
does not describe pressure changes
Answer:
Shows an inversely proportional relationship.
Explanation:
The Boyle's law belongs in the region marked X whereas the other circle belongs to Charles law. There is inverse relationship between the two circles or these two laws because in Boyle's law, temperature is constant while on the other hand, in Charles law pressure is constant instead of temperature. In Boyle's law, pressure of a gas is inversely with its volume whereas in Charles law, the volume of a gas is directly proportional to its absolute (Kelvin) temperature.
