cloud is made of small drops of water or ice crystals and to form rain, water vapour needs "Condensation Nucleus" which can be tiny particles of dust or pollen. Condensing droplets that form the cloud get large and heavy enough to overcome the upward pressure of convection, they begin to fall. Size of the drop rarely exceeds about 5mm. Larger drops do not survive as the process of surface tension which holds the drop together is exceeded by frictional drag of air. Therefore larger drops break into smaller drops. Thus drops keep on falling side by side and not in a continuous stream.
Engine oils play a crucial part in your engine’s functionality. Without the oil, your engine can become damaged fairly quickly and so it’s in your best interest to make sure that the engine oil is up to par. The oil in your engine makes sure that the all mechanical components are lubricated to reduce friction, wear and heat. The engine oil ensures that components don’t rub against each other and wear away. While it depends on how often you use your car, older engine oil doesn’t perform as well and so a regular change in engine oil is essential to the functionality of your car.
