Constructive Forces of Mountain Building
Constructive Forces of Mountain Building with Esri.
Cracked Plates & Tectonics
In this activity, you’ll investigate dynamics in Earth’s crust that explain multiple Earth science phenomena.
Parks Past, Present, and Future
Over Earth’s 4.5 billion-year history, tectonic upheavals and colliding plates formed mountain ranges and carved out basins. Forces of erosion and weathering have been at work to break down these landforms. Records of these processes are imprinted on the land and define distinctive landscapes around the United States and in its national parks.
