Which type of rock is most likely to contain organic compounds that provide evidence of past life?
A
Volcanic rock
B
Igneous rock
C
Sedimentary rock
D
Metamorphic rock
Verified step by step guidance1
Understand the types of rocks: Volcanic rocks are formed from lava or magma, igneous rocks are formed from solidified magma, metamorphic rocks are formed from existing rocks under heat and pressure, and sedimentary rocks are formed from the accumulation of sediments.
Recognize that organic compounds are typically found in environments where life has existed, and these compounds can be preserved in certain types of rocks.
Consider the formation process of sedimentary rocks: They are formed from sediments that accumulate in layers over time, often in water bodies like rivers, lakes, and oceans, where organic matter can be trapped and preserved.
Identify that sedimentary rocks are known for containing fossils and organic materials because they form in environments conducive to life and can preserve evidence of past life.
Conclude that sedimentary rocks are the most likely type to contain organic compounds that provide evidence of past life due to their formation process and ability to preserve organic matter.
