Which environment is most likely to deposit a breccia?
A) sand dunes
B) braided river
C) meandering river
D) debris flow
E) none of these are likely to deposit a breccia
Breccia
A rock composed of broken fragments of minerals or rock cemented together by a fine-grained matrix that can be similar or different in composition to the fragments.
Braided River
A river that consists of a network of small channels separated by small and often temporary islands called braid bars.
Debris Flow
Downhill-flowing slurries of loose rock, mud, and other materials, and the resulting landform and sedimentary deposit; sometimes called a mudflow.
- Recognize the environmental factors that promote the development of particular sedimentary rocks.

Final Answer :
D
Explanation :
Breccia is a sedimentary rock composed of large, angular fragments. It is typically formed in environments with high-energy conditions that can rapidly transport and deposit these large fragments. A debris flow, which is a fast-moving, high-energy flow of sediment, water, and air, can transport large, angular pieces of rock and deposit them quickly, leading to the formation of breccia. The other environments listed (sand dunes, braided rivers, and meandering rivers) generally involve the transportation and deposition of smaller, more rounded sediment particles, not the large, angular fragments characteristic of breccia.
