As engines grow older their combustion quality degrades which results in higher levels of pollutant in the exhaust fumes. An MOT test (required annually for cars older than 3 years) includes a test of the exhaust fumes to identify problems with either the engine, or the exhaust / catalytic convertor systems.

Unchecked, so called dirty cars would be allowed to continue driving on the roads producing significantly increased levels of pollution.

The rock cycle is a simplified model to show the various processes that can transform rocks over time, but in nature, rocks may skip certain stages or go through them multiple times due to complex geological processes and conditions.
