Claim: For that, we have to work on other types of marine organisms so that we clearly understand what took place in the sediment over geological time”

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: While there are many aspects of studying past and present interactions between life and Earth that are unclear, several important ideas and concepts provide a basis of knowledge in geobiology that serve as a platform for posing researchable questions, including the evolution of life and planet and the co-evolution of the two, genetics - from both a historical and functional standpoint, the metabolic diversity of all life, the sedimentological preservation of past life, and the origin of life.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: These fossils help scientists to date the core and to understand the depositional environment in which the rock units formed.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: Observation of modern marine and non-marine sediments in a wide variety of environments supports this generalization (although cross-bedding is inclined, the overall orientation of cross-bedded units is horizontal).

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: It includes the study of fossils to determine organisms' evolution and interactions with each other and their environments (their paleoecology).

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: Biostratigraphy, the use of fossils to work out the chronological order in which rocks were formed, is useful to both paleontologists and geologists.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: This involves biological and geological processes that take place over time.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: On a longer time scale, geologists must refer to the sedimentary record for data.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Numerous fossil species have been described.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Today, a variety of organisms live in and disturb the sediment.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Heinrich events are clearly observed in many North Atlantic marine sediment cores covering the last glacial period; the lower resolution of the sedimentary record before this point makes it more difficult to deduce whether they occurred during other glacial periods in the Earth's history.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: The trace fossil is found in marine and freshwater environments.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Although once thought to be a living fossil, the Chambered Nautilus is now considered taxonomically very different from ancient ammonites, and the recent fossil record surrounding the species shows more genetic diversity among Nautiluses now than has been found since the extinction of the dinosaurs.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: The interaction between marine biota and geologic processes is very important to shoreline stability, especially in soft sedimentary environments where sediments are more likely to erode away.
