A diversity of phenomena and processes has an influence on the climate, ranging from the structure and characteristics of the Earth’s surface, to processes and sources of energy deep down in the Earth’s interior. A number of these processes are extremely gradual, such as the continental drift. Others, particularly volcano eruptions, can be a major factor causing changes in the entire climate within the shortest terms.
You experience these phenomena and processes while tracing the history of a rock. Before this story begins, the outward appearance of the Earth, the character of the Earth’s surface and their influence on weather and climate are presented. There are rocks of the most varied types and forms, but all are part of a geological cycle; even the largest rocks become weather-worn. Weathering – erosion – sedimentation – tectonics – and ultimately the new formation of rocks, these are the stations along the story of the rock you are following here.
