Q: Why does neptune's appearance change?


Read this paragraph and choose the correct option from the provided answers:

Neptune's appearance changes due to its turbulent atmosphere. Winds are stronger than on any other planet in the solar system. Wind speeds can reach 1,100 km/h (700 mph). This is close to the speed of sound! The rapid winds surprised astronomers. This is because Neptune receives little energy from the Sun to power weather systems. It is not surprising that Neptune is one of the coldest places in the solar system. Temperatures at the top of the clouds are about –218°C (–360°F).

 Choices:

- the seasons

- the changing orbit

- the speed of rotation

- turbulent atmosphere


A:
turbulent atmosphere
