Coalescence
Coalescing means the pulling together of separate masses to become one bigger mass.
Explanation:
As water vapor rises into the upper cooler atmosphere, it cools and condenses into moisture droplets. These tiny droplets collide with each other, due to gravity, vertical motions and wind, to form larger droplets. This is even enhanced if there are seed particles in the air that allows the formation of larger droplets. When the droplets get large enough for gravity to act on them, they fall as precipitation.
If there are strong updrafts, the cloud could carry even larger droplets before precipitation which is what happens in the case of thunderstorms.

<span>In terms of matter and resources, the Earth is essentially a closed system, because matter and resources are fixed.
</span>In terms of energy, the Earth is an open system, because there is a balanced transfer of energy. (The energy<span> radiates into the </span>Earth's system<span>, from the Sun and</span><span> then it is radiated back into space from the </span>Earth. The<span> flows of energy are regulated by the </span>Earth's<span> atmosphere and ozone layer.)</span>
