Which of the following does NOT help define layers in some sedimentary rocks?
A) a change in mineral composition
B) a change in grain size
C) a change in color
D) a sharp contact between two rock types
E) all of these are ways that can define layers in sedimentary rocks
Mineral Composition
The unique combination and arrangement of minerals within a rock, which determines the rock's characteristics and properties.
Sedimentary Rocks
Rocks formed by the accumulation or deposition of mineral or organic particles at the Earth's surface, followed by cementation.
Grain Size
The dimension of individual particles or crystals in a solid, often determining its texture.
- Understand the processes leading to bedding and stratification in sedimentary environments.

Final Answer :
E
Explanation :
All of the options listed (a change in mineral composition, a change in grain size, a change in color, and a sharp contact between two rock types) are ways that can help define layers in sedimentary rocks. These characteristics are used by geologists to distinguish between different strata or layers within sedimentary formations.
