divergent plate boundary divergent plate boundary (dĭ-vûr'jənt) A tectonic boundary where two plates are moving away from each other and new crust is forming from magma that rises to the Earth's surface between the two plates. The middle of the Red Sea and the mid-ocean ridge (running the length of the Atlantic Ocean) are divergent plate boundaries. Also called passive margin, spreading zone. See more at tectonic boundary. Compare convergent plate boundary.

- 1 It’s a limit or edge that defines you as separate from others. 2  A boundary is a limit that promotes integrity, can preserve life and advance relationship. 3  Boundaries are physical, emotional, spiritual, sexual, relational.

Divergent boundary In plate tectonics, a Divergent boundary or divergent plate boundary (also known as a constructive boundary or an extensional boundary) is a linear feature that exists between … two tectonic plates that are moving away from each other. These areas can form on the end of continents but eventually form ocean basins.

Divergent boundary In plate tectonics, a divergent boundary or divergent plate boundary (also known as a constructive boundary or an extensional boundary) is a linear feature that exists between two tectonic plates that are moving away from each other.ver millions of years, tectonic plates may move many hundreds of kilometers away from both sides of a divergent plate boundary. Because of this, rocks closest to a boundary are younger than rocks further away on the same plate.

Convergent boundary In plate tectonics, a convergent boundary, also known as a destructive plate boundary, is a region of active deformation where two or more tectonic plates or fragments of the lithosphere are near the end of their life cycle.

Lithosphere-Asthenosphere boundary The Lithosphere-Asthenosphere boundary represents a mechanical difference between layers in Earth’s inner structure. Earth’s inner structure can be described both chemically (crust, mantle, core) and mechanically. The Lithosphere-Asthenosphere boundary (referred to as the LAB by geophysicists) lies between Earth's cooler, rigid lithosphere and the warmer, ductile asthenosphere. The actual depth of the boundary is still a topic of debate and study, although it is known to vary according to the environment.

Glossary Continental Crust A layer of the earth's crust that lies under the seven continents. It is about 20 to 40 miles (35 to 70 km) thick and very old. Convergent Boundary The boundary that occurs where two plates are pushing toward each other. Crust Hard and rigid, the earth's outermost and thinnest layer. It is only a few miles (5 km) thick under the oceans and averages 20 miles (30 km) thick under the continents.

- Continental-continental divergent/constructive boundary. In plate tectonics, a divergent boundary or divergent plate boundary (also known as a constructive boundary or an extensional boundary) is a linear feature that exists between two tectonic plates that are moving away from each other. Divergent boundaries within continents initially produce rifts which eventually become rift valleys.

Convergent Boundary: Definition, Facts & Examples A convergent boundary (or destructive boundary) is where two plates are moving towards each other -- where they're colliding. The pressure and friction is great enough at these boundaries that the material in the Earth's mantle can melt, and both earthquakes and volcanoes happen nearby.n this lesson, you will learn the meaning of the term 'convergent boundary' in the context of plate tectonics. A number of features and examples of convergent boundaries will be introduced. A short quiz will follow.

Boundary representation Boundary representation is essentially a local representation connecting faces, edges and vertices. An extension of this was to group sub-elements of the shape into logical units called geometric features, or simply features.

- Boundary features. A boundary feature is any structure that separates your property from your neighbour’s, eg a fence, wall or hedge. There are no laws about who owns these or which side of the boundary feature you’re responsible for-you can decide this in your boundary agreement.

Plate tectonics Geologists now know that the Earth's outermost layer, the lithosphere, is divided into independently moving plates into which the continents are embedded. The plates float on a layer called the athenosphere. There are different types of plate boundary.

- Above we noted that the boundary layer grows from zero when a fluid starts to flow over a solid surface. As is passes over a greater length more fluid is slowed by friction between the fluid layers close to the boundary. Hence the thickness of the slower layer increases. The fluid near the top of the boundary layer is dragging the fluid nearer to the solid surface along.

An example of a convergent boundary is? Convergent boundary. In plate tectonics, a convergent boundary, also known as a destructive plate boundary (because of subduction), is an actively deforming region where two (or more) tectonic plates or fragments of the lithosphere move toward one another and collide.

Boundary Boundary is a border that encloses a space or an area. The distance around the boundary is called as 'perimeter'. The length of the three sides of a triangular field is 9 m, 5 m, and 11 m. The boundary or perimeter of the field is given as 9 m + 5 m + 11 m = 25 m.

What is a transition zone? Why are some larger than others? The lower boundary separating the upper and lower mantle - is a transitional zone. The transition zone is located in the depth interval 400 - 650 kilometers from the Earth's surface. The transition zone is an area of great complexity; it physically separates the upper and lower mantle.
