The clouds float in the atmosphere because of their low
- temperature
- velocity
- pressure
- density
Explanation
Option (d) is correct
- Clouds consist of tiny water droplets or ice crystals suspended in the atmosphere. They remain aloft because the droplets are extremely small and have very low terminal velocities, allowing gentle updrafts to keep them suspended. As a result, the cloud parcel (air plus droplets) often has a lower effective density than the surrounding air, creating buoyancy that prevents it from settling. Thus, low density, along with upward air currents, keeps clouds suspended.
