10 Φεβ 2024 · The tectonic plates connect the parts of Earth’s lithosphere, much like the pieces of a jigsaw puzzle. Unlike puzzle pieces, tectonic plates do not rest on a stable surface. Instead, they float on the moving, semi-liquid portion of the mantle, called the asthenosphere.
7 Μαρ 2024 · Plate tectonics is a scientific theory that explains how major landforms are created as a result of Earth’s subterranean movements. The theory, which solidified in the 1960s, transformed the earth sciences by explaining many phenomena, including mountain building events, volcanoes, and earthquakes. In plate tectonics, Earth’s outermost ...
Investigate questions about tectonic plates, which make up the outer shell of the earth. Build and test your own seismograph, which detects and records ground motion . Or use free online tools and databases to find patterns in seismic activity.
What is a Plate? The surface of the Earth is broken up into large plates. It’s easy to confuse these plates with the Earth’s crust – the thin outermost layer of the Earth. But there is more to the structure of the Earth than this simple image of a ‘cracked egg-shell’.
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.
17 Σεπ 2024 · Use National Geographic MapMaker to guide students through an analysis of Earth’s tectonic plates, how they interact, and shape the location of physical features.
Realising the plates are dynamic led to new insights into our understanding of the planet and revolutionised and unified the Earth sciences – from the study of fossils (paleontology) to the study of earthquakes (seismology).
