This is to represent a period of time in which nothing relative happened and would otherwise take up space on the timeline .
eg.
History of Technology
Start of time-(jagged break)-Invention of fire---Invention of Wheel---(etc.)
In a timeline what does a jagged line mean
A mineral that breaks into jagged pieces exhibits fracture.
Jagged lines have toothed/serated edges whereas diagonal lines can have any edge so long as they run diagonally,so it is possible to have a jagged diagonal line!
The answers are: *vertical lines *horizontal lines *jagged lines *dynamic lines
Limestone, and sulfur.
Quartz is a common mineral that breaks with rough or jagged edges. This is due to its brittle nature and the way its atomic structure breaks along planes of weakness when subjected to stress.
Jagged lines are commonly used in various real-life contexts, such as in graphic design to create dynamic and energetic visuals, often seen in logos or advertisements to attract attention. In nature, jagged lines can be observed in mountain ranges or jagged coastlines, which add dramatic effect to landscapes. Additionally, in art, jagged lines are used to convey tension or chaos, as seen in the works of expressionist artists. Finally, in architecture, jagged lines can create striking designs in modern buildings, emphasizing uniqueness and creativity.
When it breaks, it breaks in big jagged pieces.

Jagged lines on a seismogram indicate the ground shaking caused by seismic waves during an earthquake. The amplitude of the jagged lines represents the intensity of the shaking, with larger amplitudes indicating stronger shaking. The frequency and duration of the lines can also provide information about the earthquake's magnitude and distance from the recording site.
When a mineral breaks into jagged pieces, it is called a "fracture." This occurs when the mineral does not break along cleavage planes, resulting in rough and irregular surfaces. Fracture types include conchoidal (shell-like), fibrous, splintery, and uneven.
Time zone borders are jagged because they follow political borders.
