Detailed explanation-1: -A student examines a rock with the imprint of a leaf in it. Which conclusion can the student reach regarding the process of formation of the rock? It formed by erosion of sediments.
Detailed explanation-2: -What is the most logical conclusion about a layer of rock near the top of a canyon? The layers near the top are younger than layers below.
Detailed explanation-3: -Fossils provide important evidence for evolution and the adaptation of plants and animals to their environments. Fossil evidence provides a record of how creatures evolved and how this process can be represented by a ‘tree of life’, showing that all species are related to each other.
Detailed explanation-4: -Fossils tell about the ancient organisms’ life and their evolution on earth millions of years ago. Fossils are direct evidence of evolution. It tells about the life found on ancient earth. By studying fossil records palaeontologists reveal the connecting link between different organisms of the past and present.
Detailed explanation-5: -Fossils, along with the comparative anatomy of present-day organisms, constitute the morphological, or anatomical, record. By comparing the anatomies of both modern and extinct species, paleontologists can infer the lineages of those species.
