Question

Sedimentary rocks are formed from the weathered products of precursor rocks, deposited at or near the surface of the Earth, and commonly provide useful information about Earth's past climate, landscape, and living organisms. They also contain much of Earth's store of valuable energy and mineral resources. Which of the following statements is true about sedimentary rocks?

: They are formed from the weathered products of precursor rocks
: They are deposited at or near the surface of the Earth
: They commonly provide useful information about Earth's past climate, landscape, and living organisms
: They contain much of Earth's store of valuable energy and mineral resources
: All of the above

Answer 1

Sedimentary rocks form from the weathered remnants of other rocks, provide insights into Earth's past climates and landscapes, and contain valuable energy and mineral resources. They include types like clastic and organic, important for natural resource extraction.

Step-by-step explanation:

Sedimentary rocks are key to understanding Earth's past. They form from the weathered products of precursor rocks and are deposited at or near the Earth's surface, often containing fossils and minerals that provide a historical record of past climates, landscapes, and organisms. These rocks include various types such as clastic, chemical, and organic, all of which hold vital clues about environmental history and resources. Clastic sedimentary rocks, for instance, form from the accumulation of material like sand and clay, while organic sedimentary rocks are made from the lithification of plant and animal material, leading to the formation of natural resources like coal and petroleum.

Energy and mineral resources, such as coal, natural gas, petroleum, and salts, are often found within sedimentary rocks. Understanding the formation and composition of these rocks is essential for locating and extracting these valuable materials. Moreover, identifying and studying sedimentary structures can reveal information about the initial environmental conditions and the mechanisms of transport, such as water or wind, that led to their deposition.
