Tectonic activity (170 – 40 million years ago) that resulted in much of the rugged landscape of the western North America. Describe the process that most likely formed this mountain range

A process known as Subduction

Explanation:

In the event that two tectonic plates collide, they structure a convergent plate boundary. Typically, one of the converging plates will move underneath the other, a procedure known as subduction. Profound trenched are included frequently where tectonic plates are being subducted and earthquakes are normal. As the sinking plate moves further into the mantle, fluids are discharged from the rock making the overlying mantle to somewhat melt. The new magma ascents and may emit fiercely to frame volcanoes, regularly forming curves of islands along the convergent boundary.

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
