However, volcanoes sometimes erupt in the middle of tectonic plates. The sources of these hotspots might be mantle plumes, mushroom-shaped pillars of hot rock ascending from the deep mantle to sear overlying material like a blowtorch. As tectonic plates wander over such plumes, geologists think ...
Many of these hotspots occur far away from tectonic plate boundaries. Hawaii, for example, is in the middle of the Pacific plate, and its active volcanoes are fed by a long conduit of magma that is piped up from the mantle. The volcanoes in Iceland are unique because they form from two...

When the Earth’s tectonic plates move over hotspots, they leave a path with evidence we can see, such as the remnants of the Pacific Plate’s movement over the Hawaiian hotspot being much longer than just the above-water islands that magma flowing up through the volcanoes created. In fact...
1. TED-Ed Lesson – How Ocean Currents Work This TED-Ed lesson featureshow ocean currents work. It starts with a story of how rubber ducks got swept away by ocean currents. Then, it gets into what influences ocean currents. For example, the wind, tides, water density, rotation, and eve...
