Question

what are disadvantages of sundial clocks ?

Answer 1

A sundial doesn't work at night.

A sundial doesn't work when the sun is hidden - by clouds, buildings, etc.

A sundial only works at the latitude it is designed for - a sundial built for Ecuador woudl not be accurate in New Zealand.

Answer 2

Explanation:

Although the Sundial is very simple to make and to use, it also has many disadvantages. A Sundial is no longer accurate after a month. This is because the obliquity of Earth causes the 'path' of the Sun to change over the months. The same Sundial cannot be used in two different places
