A air front is typically a transition zone between two unique temperature/humidity. Usually, one front would push the other away (typically if summer is hot, then the warm front will push away the cold, and for the winter, if it's cold, it's the opposite).
A stationary front, on the other hand, is when there is no change in the over all temperature for the region(s), and a occluded front is when the fronts mix, where it is followed by rain and a equillibrium of the temperature, whether to a warmer or cooler overall temperature.

How does fossils record help scientists observe changes in organism over time ?
As the world changes, plants and animals change with it. Aside from a few living fossils, the species we see today are very different from species that lived in the past.
What is the minimum age of a fossil?A living being that lived more than 11 thousand years ago is considered a fossil, that is, before the Holocene, which is the current geological epoch.
Ancient remains or evidence, but less than 11,000 years old, such as sambaquis, are classified as subfossils.
The dating of a fossil can be done based on the already known percentage of Carbon-14 (C14) in relation to Carbon-12 (C12) of living matter (without decomposition).
Thus, the fossil record can be used to show that organisms changed to meet new conditions.
