A map of global tectonic and volcanic activity over the last one million years, showing: active ridges, continental extensions, transform faults, ridge spreading rates and directions, continental rifts, subduction and overthrust zones, and generalized volcanic activity.
20 Ιουν 2024 · an opening in the Earth's crust, through which lava, ash, and gases erupt, and also the cone built by eruptions. Explore the boundaries between Earth's tectonic plates with MapMaker, National Geographic's classroom interactive mapping tool.
19 Οκτ 2023 · Geologists studying the Earth use scientific observation and evidence to construct a picture of what the Earth looked like at different periods in the geologic past. Use this map gallery to better understand how plate tectonics created the ocean and continents we are familiar with today.
Tectonic Tessellation Playground. Instructions: Set one of the two positions (A or B) to adjust. These points are the beginning and end position for the animation. Each land mass can be adjusted by modifying their x, y, and z axis rotation (this can be tedious). You may drag the earth to see different views.
Features include: Plate tectonics. Cross-section view. Rock types. Rock sampler tool. Temperature and pressure tool.
14 Ιουν 2004 · These images show the locations of the plates and their boundaries in the Earth's crust. Convergent boundaries are areas where two plates are pushing against each other and one plate may be subducting under another.
