The Andes Mountains are the world’s longest continental Folded mountain range. They formed at a convergent boundary where the oceanic Nazca Plate subducts beneath the South American Plate. This compression, combined with significant volcanic activity, created the massive, elongated cordillera ...

Attenuation is the weakening of seismic waves as they move away from the source. This happens because the energy spreads over a larger area (geometric spreading) and is absorbed by the rocks (frictional heating). High-frequency waves attenuate faster than low-frequency ...
Mount Erebus is located in Antarctica, specifically on Ross Island. It is the southernmost active volcano on the planet. Its location in one of the harshest environments on Earth makes it a unique subject for scientific research regarding how volcanic ...
An Earthquake is currently the most unpredictable natural disaster. While meteorologists can track cyclones, hurricanes and tornadoes using satellites and pressure systems, seismologists have no way to predict exactly when a fault will rupture. We can identify “where” (high-risk zones) ...
Statement (B) is incorrect because the Richter scale is a mathematical formula (a scale), not a physical instrument. The instrument used to detect and record earthquakes is the seismograph. Additionally, the Richter scale measures magnitude (energy released), while intensity (damage/shaking) ...
