Seismogram
A seismogram is a chart created by a seismograph, a device that detects earthquakes and deformations. These graphs allow us to locate the epicenter of an earthquake, determine its magnitude, and identify the depth of focus.
Richter Scale
The Richter scale indicates the magnitude of an earthquake. It is logarithmic and has values from 1 to 10 degrees of elastic energy. For each degree of increase, the earthquake is 10

Fairy Chimneys: Pyramidal Landforms
Fairy chimneys are huge pyramids topped with rocks. These landforms are created when water carries away the finest materials, leaving behind areas protected by water-resistant rocks.

Crystalline Rocks
The most common rocks in the Earth system consist of crystals. They are heterogeneous rocks that comprise heterogeneous crystals, all visible, and are called plutonic. The most important are:
- Granite: A coherent rock, usually gray but sometimes pink. The following are distinguished:
- Quartz: Gray, almost transparent crystals with a vitreous luster.
- Feldspars: The most abundant crystals, sometimes white with pink.
- Mica: Black crystals that are very bright.
Granite is the most abundant
