GEOLOGY

Detailed explanation-1: -Both breccia and conglomerate are composed of fragments averaging greater than 2 millimetres (0.079 in) in length.

Detailed explanation-2: -breccia, lithified sedimentary rock consisting of angular or subangular fragments larger than 2 millimetres (0.08 inch). It differs from a conglomerate, which consists of rounded clasts.

Detailed explanation-3: -A clastic rock made of particles larger than 2 mm in diameter is either a conglomerate or breccia. A conglomerate has rounded clasts while a breccia has angular clasts. Since water transport rapidly rounds large clasts, breccias normally indicate minimal transport.

Detailed explanation-4: -Conglomerate is composed of particles of gravel, that is to say of particles of greater than 2 mm in diameter, consisting, with increasing size, of granules, pebbles, cobbles, and boulders.

Detailed explanation-5: -Clastic sedimentary rocks in which a significant proportion of the clasts are larger than 2 mm are known as conglomerate if the clasts are well rounded, and breccia if they are angular. Conglomerates form in high-energy environments where the particles can become rounded, such as fast-flowing rivers.
