Final answer:
People may not be aware of changes below ground due mainly to the inaccessibility of these areas and the slow nature of geological processes. The steadier conditions underground also help in hiding food reserves from predators when compared to the surface where conditions can vary widely.
Step-by-step explanation:
People are often unaware of changes happening below the ground for various reasons, but the most significant among them is inaccessibility to underground areas. It is challenging to study the Earth's interior because we lack direct access. The slow geological processes also play a part, as many events such as the movement of tectonic plates or the formation of rocks occur over long periods, which can span thousands to millions of years. Furthermore, the idea that geologic change is the result of slow, continuous processes rather than sudden changes aligns with Darwin's hypothesis on gradual biological change over time. Technologies have improved our knowledge, but there are still significant limitations to how much we can see and measure, particularly at greater depths.
When considering the question of why food reserves underground are hidden from potential predators and why the soil conditions such as moisture and temperature are less variable, we must look at the biology of the organisms and the soil conditions that help create a stable environment for these reserves. The underground environment tends to be more consistent in terms of these conditions when compared to surface environments, which can fluctuate more dramatically because of weather and climate changes.
