I think its the temperature and precipitation
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.

The equatorward bending of height contours for the 500 mb level imply the presence of a trough because this represents a region of overall lower heights. A valley and a trough are hence equivalent in the upper air flow.
A trough is a linear structural depression with lateral length that occurs in geology. A trough can be a small basin or a natural rift, albeit it is lower than a trench. At the edge of tectonic plates, these landforms frequently form.
Trough, an extended depression in the seafloor that differs from oceanic trenches in that it is shallower, shorter, narrower, and topographically more mild. The Papuan Trough's maximum depth is 2,300 m (7,500 feet), while the Banda Trough's maximum depth is 7,440 m.

The correct answer is - greenhouse gases.
The humans have been having a very big impact on the composition of the atmosphere in the past century, and that has started to result into changes in the climate patters all over the globe.
The main problem appears with the huge amounts of greenhouse gases released into the atmosphere, mostly carbon dioxide, but also methane. These two gases have properties that enable the greenhouse effect, which means that they are able to trap bigger amount of heat in the Earth's atmosphere, thus making it warmer.
If the ongoing trend continuous with the release of the greenhouse gases there will for sure be devastating effects on everyone and everything on the planet not so far in the future.
One of the most common forms of weathering in areas that have frequent freeze/thaw cycles is ice wedging.
