What is an agglomerate rock?
agglomerate, large, coarse, rock fragments associated with lava flow that are ejected during explosive volcanic eruptions. Although they closely resemble sedimentary conglomerates, agglomerates are pyroclastic igneous rocks that consist almost wholly of angular or rounded lava fragments of varying size and shape.
What is the definition of agglomerate?

What is agglomerate used for?

What is the difference between conglomerate and agglomerate?
As adjectives the difference between conglomerate and agglomerate. is that conglomerate is clustered together into a mass while agglomerate is collected into a ball, heap, or mass.
Where is agglomerate found?
volcanic vents
Agglomerates are typically found near volcanic vents and within volcanic conduits, where they may be associated with pyroclastic or intrusive volcanic breccias.
What are agglomerated materials?
Agglomerates are particulate materials consisting of large particles formed by the joining or binding together of primary particles whose original identity can still be visible in the final agglomerate form. The term can refer to: Cluster of molecules or particles that results from agglomeration.
What does agglomerated mean in science?
1 : the action or process of collecting in a mass the agglomeration of matter into stars and galaxies. 2 : a heap or cluster of usually disparate (see disparate sense 1) elements …
Why do nanoparticles agglomerate?
Agglomeration of nanoparticles is due to adhesion of particles to each other by weak forces leading to (sub)micronsized entities. In contrast, nanoparticle aggregates are due to the formation of covalent or metallic bonds that cannot be easily disrupted.
What is agglomerate soil?
Agglomerate (from the Latin agglomerare meaning “to form into a ball”) is a coarse accumulation of large blocks of volcanic material that contains at least 75% bombs. Agglomerates are typically poorly sorted, may contain a fine ash or tuff matrix and vary from matrix to clast support.
What is the difference between a corporation and a conglomerate?
Conglomerates differ from corporations in that a conglomerate must have wholly or partially owned subsidiary companies. A subsidiary is a company that is owned by another company. Corporations may or may not have subsidiaries. To become a conglomerate, a company must first register as a corporation.
What is the difference between agglomeration and aggregation?
Aggregation is a definite pattern of molecules which may be in any state, while agglomeration is only a process where in gathering into a mass in solid state. On the other hand, a agglomerate does not require a definite pattern, shape, size.
What causes particles agglomerate?
What kind of rock is an agglomerate made of?
Although they closely resemble sedimentary conglomerates, agglomerates are pyroclastic igneous rocks that consist almost wholly of angular or rounded lava fragments of varying size and shape. Fragments are usually poorly sorted in a tuffaceous matrix, or appear in lithified volcanic dust or ash.
Which is the best definition of the word agglomerate?
3. a mass of things clustered together. 4. rock composed of rounded or angular volcanic fragments. [1675–85; < Latin agglomerātus, past participle of agglomerāre to pile up] ag•glom′er•a`tive (-əˌreɪ tɪv, -ər ə tɪv) adj.
How is an agglomerate different from a volcanic bomb?
Agglomerate. Agglomerate (from the Latin agglomerare meaning “to form into a ball”) is a coarse accumulation of large blocks of volcanic material that contains at least 75% bombs. Volcanic bombs differ from volcanic blocks in that their shape records fluidal surfaces: they may, for example, have ropy, cauliform, scoriaceous, or folded,…
How are crystalline masses formed in an agglomerate?
Crystalline masses of a different kind occur in some numbers in certain agglomerates. They consist of volcanic minerals very much the same as those formed in the lava, but exhibiting certain peculiarities which indicate that they have formed slowly under pressure at considerable depths.
