Most of source rocks are light grey?

a. Flase
b. True

To determine whether most source rocks are light gray, we can start by understanding what source rocks are. Source rocks are sedimentary rocks or organic-rich shale formations that contain a sufficient amount of organic matter to generate hydrocarbons.

To answer the question, we need access to sources of information such as geological surveys, research papers, or textbooks. We can start by searching for information on source rocks and their characteristics. This can be done through various means, such as:

1. Online research: Using search engines like Google, Bing, or scholarly databases, search for information on source rocks, including their composition, color, and common characteristics.
2. Accessing geological databases: Government agencies and geological surveys often provide access to geological information, including data on rock types and their properties.
3. Consulting textbooks: Geology textbooks, specifically those focused on sedimentary rocks or petroleum geology, often cover the topic of source rocks and their characteristics.

By reviewing these sources, we can find reliable information regarding the color of source rocks. It is important to note that source rocks can come in various colors, as the color depends on the mineral composition, organic content, and geological history of the rock formation. Therefore, it is not accurate to state that most source rocks are light gray without referring to specific geological contexts or sources.
