Summary(Plain Language Summary, not published)
Quebec City is located at the junction of three geological provinces, bestowing upon it a geological panorama without compare and which includes a historical district that dates back to the first days of the colony. Since 2004, Natural Resources Canada has been organizing, in collaboration with Parks Canada, an urban tour through the streets of Old Quebec, combining geology and history with a multidisciplinary perspective. Quebec City's geological history goes back more than a billion years and can be explained by plate tectonics. According to this theory, Earth's crust is divided into plates that slowly move against one another. With the selected stops, fieldtrip participants will discover clues to a long-disappeared ocean, the movement of massive rock masses over long distances, up to the very threshold of the city, and the passage of immense glaciers that covered the re-gion for thousands of years. We live on a dynamic planet and various elements remind us of this on a periodic basis. We will also see how earthquakes and scree are the result of the region's geological heritage.
