Answer 1

Answer:

Some of the clocks used in early times include incense clock, candle clock, sundial, sand clock or hourglass, pendulum clock, etc. Sundial clock uses sun for indicating time. Hourglass or snad clock works on the principle that gravity causes the grains of sand to flow through a small neck in the glass container.

Explanation:

The incense clock (simplified Chinese: 香钟; traditional Chinese: 香鐘; pinyin: xiāngzhōng; Wade–Giles: hsiang-chung; lit. 'fragrance clock') is an Indian timekeeping device that was popularised by China during the Song Dynasty (960-1279) and spread to neighboring East Asian countries such as Japan and Korea.

candle clock is a thin candle with consistently spaced marking that when burned, indicate the passage of periods of time. While no longer used today, candle clocks provided an effective way to tell time indoors, at night, or on a cloudy day.
