Scientists determine where one layer ends and the next one begins by examining changes in sediment type, color, grain size, or fossil content. These changes often represent different time periods or environmental conditions that help scientists distinguish between layers. Additionally, techniques like radiometric dating can provide precise age estimates for different layers.

How can you tell where one layer ends and another begins in the atmosphere?
Layers in the atmosphere are defined by changes in temperature. The boundary between each layer is known as a pause, where the temperature gradient changes direction. These pauses create distinct boundaries between layers like the troposphere, stratosphere, mesosphere, and thermosphere.
What is startosphere?
The point at which the stratosphere begins, the tropopause, is measured by where this temperature inversion starts taking place. The height of the stratosphere varies depending on what latitude we are talking about: at moderate latitudes, the stratosphere begins about 10 km (6 mi) above the surface and ends at 50 km (31 mi), at the poles, it starts at only 8 km (5 mi) altitude. This is because the ground at the poles is so cold, it doesn't take much to produce greater temperatures, and thus the stratosphere begins earlier.
