GEOLOGY

Detailed explanation-1: -Rock strata refers to stacked-up layers of sedimentary rock. Other kinds of rock can have layering in them but the word ‘strata’ is reserved for sedimentary rocks, rocks composed of individual fragments of minerals or other rocks. The root word also lends itself to other geologic terms.

Detailed explanation-2: -In geology and related fields, a stratum (PL: strata) is a layer of rock or sediment characterized by certain lithologic properties or attributes that distinguish it from adjacent layers from which it is separated by visible surfaces known as either bedding surfaces or bedding planes.

Detailed explanation-3: -The most important geological processes that lead to the creation of sedimentary rocks are erosion, weathering, dissolution, precipitation, and lithification. Erosion and weathering include the effects of wind and rain, which slowly break down large rocks into smaller ones.

Detailed explanation-4: -The sedimentary rocks contain layers or strata. They are therefore often known as stratified rocks.
