Earth Dynamics During the Stone Age

The Stone Age occurred much more recently, beginning roughly 3.3 million years ago and lasting until the development of widespread metalworking. Unlike the Mesozoic Era, the Stone Age was characterised by the emergence and development of early humans.
Large portions of northern Europe, Asia, and North America were periodically covered by massive ice sheets. Global temperatures changed considerably between colder glacial periods and warmer interglacial periods. These climatic changes influenced sea levels, vegetation, animal migration, and human settlement patterns. When large quantities of water were stored in glaciers, sea levels fell, exposing land bridges between regions that are now separated by oceans.
The Stone Age landscape was also shaped by rivers, glaciers, erosion, volcanic activity, and changing vegetation.Humans adapted to these changing environments by hunting animals, gathering plants, controlling fire, developing tools, and eventually practising agriculture.During the later Stone Age, the development of farming and permanent settlements began to significantly alter local landscapes through deforestation, cultivation, and domestication of animals.
The Earth during the Age of Dinosaurs and the Stone Age was vastly different from the world we know today. Dinosaurs lived on a planet shaped by continental movement, warm climates, high sea levels, volcanism, and major evolutionary changes. Millions of years later, early humans experienced a planet strongly influenced by repeated ice ages, changing sea levels, shifting ecosystems, and climatic fluctuations. 
These periods demonstrate that Earth is not a static planet. Its geography, climate, atmosphere, and living organisms continuously interact and change over geological time. Understanding these past Earth dynamics helps us understand the natural processes that continue to shape our planet today.
