Cryovolcano, which is considered the most probable mechanism to explain geological activity on some satellites of the outer planets, may indeed be possible for TNOs larger than about 1000 km.

The probable mechanisms are thus two possibilities:

The most probable mechanism involves the elimination of an alkyl anion as the final step:

While deexcitation can occur by emission of photons, more probable mechanism at atmospheric pressure is a chemical reaction with other oxygen molecules, forming ozone:

It can be assumed that on a multi-lane road the most probable mechanism of over-acceleration is lane changing to a faster lane.

Research at the University of Colorado at Boulder revealed a probable mechanism for the carcinogenic effects of mothballs and some types of air fresheners.

The aetiology of injury to the fetus is debated, but a probable mechanism is manual stretching of the nerves, which in itself can cause injury.

Previous studies have confirmed the beneficial effect of frequent contact with nature and some have investigated the probable mechanism of the effect via stress abating biochemical processes,,,.

By painstaking analysis of its structures, he worked out the probable mechanism of pollination.
