Earth 's Internal Structure

Types of Plate Boundaries

Plate boundaries are classified according to thee relative motion of adjacent plates. Each boundary type is associated witch criteristic geological facilites andd hazards.

Divergent Boundaries

At divergent boundaries, plates move apart from one anotherr. This separation allows magma frem thee astenosfera to rise and solidify, forming new oceanic cruct. The most extensive divergent boundary system on Earth is the mid- oceaun ridgee network, which spens approximatele 65,000 kilometers. Thee Mid- Atlantic Ridgge, for example, separates thee North American Plate frem the Eurasian Plate and thee South American Plate from theh Africé Plate.

Te łatwe Afrykanie Rift System is a prime example, when te African Plate is splitting into the Nubian and d Somalian plates. If rifting contines, a new ocean basin may eventually form, as happed whether South America separated from Africa.

Konwergent Boundaries

Konwergent boundaries occur plates where plates collide. The outcome depends on thee type of cruct involved. When an oceanic plate converges with a continental plate, thee denser oceanic plate subductes beneath the continental plate, forming a deep ocean trench andd a chain of wulkanic mountains thee contingent. The Andes, created by the subductiof thee Nazca Plate beneath the South American Plate, ilstrate thies process.

Seismographs are instruments that detect and record ground motion caused by seismic waves. They produce seismograms that allow scientists to determine the location, magnitude, and depth of an earthquake. The Richter scale, developed in 1935, measures the amplitude of seismic waves and provides a logarithmic magnitude value. However, the moment magnitude scale (Mw) is now more commonly used because it more accurately estimates the total energy released by large earthquakes.

Earthquake intensity, which describes the effects on course and structures, is assessed using the Modified Mercalli Intensity scale. This scale ranges from I (notfelt) to XII (total destruction) and is based on observed damage andd human perception.
