Hi,
Scientists have used rock samples to date the Earth's past. They also might use Steno's principles.
Relative dating is the determination of the age of a rock or geological event by comparing with other rock/ geologic events. Absolute dating is a form of geologic dating that gives an actual date or age in history that the item was formed or died in years.
Steno's principles are:
Law of superposition - Bottom layer is the oldest, top layer of the youngest In undisturbed layers of sedimentary rock or magma.
Original horizontally - When sedimentary rock layers form, they are "created in a horizontal form.
The Principle of Lateral Continuity -<span> States that layers of sediment initially extend </span>laterally<span> in all directions.

Answer:
Gran papel.
Explicación:
La historia ha hecho grandes contribuciones al desarrollo de la cartografía. El descubrimiento de nuevas tierras a través del viaje de personas en el mar permite al mundo trazar un mapa de la tierra. Estos mapeos dan información a diferentes países y se produce la transferencia de cultura, humanos y otros materiales. Este mapeo también permite a las personas comerciar en lugares lejanos. De esta manera se inició el comercio entre diferentes países. Entonces podemos decir que la historia juega un gran papel en el desarrollo de la cartografía.
25,000 = 2.5 x 10^4
250 = 2.5 x 10^2
0.025 = 2.5 x 10^-2
0.00025 = 2.5 x 10^-4 :D
