Hailstone, Fog, Dew, and Snowflakes: Different Shapes and Characteristics

Introduction:
The question asks which of the given options falls in different shapes. Let's analyze each option and determine the correct answer.

Hailstone:
- Hailstones are solid precipitation that falls from thunderstorms.
- They are spherical or irregularly shaped.
- Hailstones can vary in size, ranging from small pebbles to large golf balls or even larger.
- Due to their formation process, hailstones often have a layered structure.

Fog:
- Fog is a cloud that forms near the ground when air cools and condenses.
- It consists of tiny water droplets suspended in the air.
- Fog doesn't fall in the same sense as precipitation; it remains close to the surface.
- The shape of fog is not well-defined and can vary depending on the surrounding landscape and weather conditions.

Dew:
- Dew forms when the temperature of an object (such as grass or leaves) drops below the dew point, causing moisture in the air to condense.
- Dew appears as tiny water droplets on surfaces like grass or car windshields.
- It doesn't fall from the sky but forms on objects due to temperature changes.
- The shape of dew droplets depends on the surface they form on and can be round or irregular.

Snowflakes:
- Snowflakes are ice crystals that form when water vapor freezes in the atmosphere.
- They have intricate and symmetrical shapes with six arms or branches.
- Each snowflake is unique due to the complex process of ice crystal formation.
- Snowflakes can have various shapes, including hexagonal plates, columns, dendrites, and needles.

Conclusion:
Among the given options, the correct answer is option 'D' - Snowflakes. Unlike hailstones, fog, and dew, snowflakes have distinct and intricate shapes with six-fold symmetry. Hailstones are spherical or irregular, fog is formless, and dew appears as tiny droplets on surfaces.
