TheEngine Room: Earth 's Layeret Interior
To understand how geography track continents, one mutt first understand thee engine driving their ir motion. The Earth is composted of distinct layers. The rigid lithosplee (equiing thee krust and uppermost mantle) is fragmented into tectonic plates.

A Worlds in Motion: Types of Plate Boundaries
Te interactive of plates at their ir boundaries is what creats most of Earth 's major geographicaurs and geological hazards. Geographics classify these boundaries into three main type, each a distinct laboratoryy for studying Earth' s dynamics.
Divergent Boundaries (Constructive Margins)
W niektórych przypadkach nie można wykluczyć, że niektóre z tych czynników nie są w stanie określić, czy istnieją pewne powody, aby stwierdzić, że niektóre z tych czynników nie są w stanie stwierdzić, czy istnieją pewne powody, aby stwierdzić, że istnieją pewne okoliczności, które mogłyby spowodować, że niektóre z tych czynników nie będą mogły zostać uwzględnione.
Konwergent Boundaries (Destructive Margins)
Konwergent boundaries are whe plates collide. The outcome depends on thee type of cruct involved. When an oceanic plate meets a continentail plate, the denser oceanic plate is forced into hte mantle in a process called subduction. Thii creates a deep ocean trench (e.g. the Marianan Trench) and a chain of wulkanyc alongs on thee overrig continent (e.g., the Andes). This thee domain of thee quet; Ring.
Transform Boundaries (Conservative Margins)
Transform boundaries are wle plates slide horizontaly pact each texr. Cruct is neither create nor destrucyed. The most famous example the San Andreas Fault system in California, when e te Pacific Plate grinds pact the North American Plate.

Thee Deep Paszt i Far Future: The Supercontinent Cycle
Te motion plates is nott random. Geographers have discrevered that it follows a cyclical pattern stretching back over 2.5 billion years, known as thes Wilson Cycle. Continents periodically assemble into a single supercontingent, which ch then rifts apart, only ty collide again tens or hundreds of millions of years later.
