Cannabinoids begin to vaporize around 284 F, combustion doesn't begin until 446 F
Yes, think of temperature control as the key to unlocking the full array of effects a strain can offer. Higher temperatures exaggerate effects, while lower temps offer a gentler experience because of the terpenes that are burnt off at certain temperatures. Temperature is basically the volume knob, turn it up for intensity. Start at 330 F and go up from there.
Vaporization is the purest way to consume cannabis because it does not burn the cannabis flower or concentrate and vaporizes.
