  2. Lithosphere–asthenosphere boundary - Wikipedia

    en.wikipedia.org/wiki/Lithosphere–asthenosphere...

    A diagram of the internal structure of Earth. The lithosphere consists of the crust and upper solid mantle (lithospheric mantle). The green dashed line marks the LAB. The lithosphere–asthenosphere boundary (referred to as the LAB by geophysicists) represents a mechanical difference between layers in Earth's inner structure.

  3. Internal structure of Earth - Wikipedia

    en.wikipedia.org/wiki/Internal_structure_of_Earth

    The transition between the inner core and outer core is located approximately 5,150 km (3,200 mi) beneath Earth's surface. Earth's inner core is the innermost geologic layer of the planet Earth . It is primarily a solid ball with a radius of about 1,220 km (760 mi), which is about 19% of Earth's radius [0.7% of volume] or 70% of the Moon 's radius.

    The Motagua Fault, which crosses through Guatemala, is a transform boundary between the southern edge of the North American plate and the northern edge of the Caribbean plate. New Zealand's Alpine Fault is another active transform boundary. The Dead Sea Transform (DST) fault which runs through the Jordan River Valley in the Middle East.

    Mantle – Layer inside a planet between core and crust; Mohorovičić discontinuity – Boundary between the Earth's crust and the mantle; Mountain – Large natural elevation of the Earth's surface; Mid-ocean ridge, also known as Oceanic ridge – Basaltic underwater mountain system formed by plate tectonic spreading

  6. Boundary problem (spatial analysis) - Wikipedia

    en.wikipedia.org/wiki/Boundary_problem_(spatial...

    A boundary problem in analysis is a phenomenon in which geographical patterns are differentiated by the shape and arrangement of boundaries that are drawn for administrative or measurement purposes. The boundary problem occurs because of the loss of neighbors in analyses that depend on the values of the neighbors.

  7. Contact (geology) - Wikipedia

    en.wikipedia.org/wiki/Contact_(geology)

    A geological contact is a boundary which separates one rock body from another. [1] A contact can be formed during deposition, by the intrusion of magma, [2] or through faulting or other deformation of rock beds that brings distinct rock bodies into contact.

  8. System context diagram - Wikipedia

    en.wikipedia.org/wiki/System_context_diagram

    Example of a system context diagram. [1] A system context diagram in engineering is a diagram that defines the boundary between the system, or part of a system, and its environment, showing the entities that interact with it. [2] This diagram is a high level view of a system. It is similar to a block diagram.

  9. Transform fault - Wikipedia

    en.wikipedia.org/wiki/Transform_fault

    A transform fault or transform boundary, is a fault along a plate boundary where the motion is predominantly horizontal. [1] It ends abruptly where it connects to another plate boundary, either another transform, a spreading ridge, or a subduction zone. [2] A transform fault is a special case of a strike-slip fault that also forms a plate boundary.
