Fossil succession relative dating
We find fossils such as sea shells, imprints of plants and animals, and burrows from worms that crawled through the soil long before man existed.
In the high Himalayan peaks we find fossils of life forms that lived in oceans long ago.
Our Earth has been around for approximately 4.6 billion years.
Rocks are full of evidence that life formed on Earth nearly four billion years ago.
C understand how multiple dating methods are used to construct the geologic time scale, which represents Earth's approximate 4.6-billion-year history 8.
The student is expected to 8 The student knows that fossils provide evidence for geological and biological evolution. A evaluate relative dating methods using original horizontality, rock superposition, lateral continuity, cross-cutting relationships, unconformities, index fossils, and biozones based on fossil succession to determine chronological order 7.
A demonstrate safe practices during laboratory and field investigations; 1.
I communicate valid conclusions supported by data using several formats such as technical reports, lab reports, labeled drawings, graphic organizers, journals, presentations, and technical posters. A in all fields of science, analyze, evaluate, and critique scientific explanations by using empirical evidence, logical reasoning, and experimental and observational testing, including examining all sides of scientific evidence of those scientific explanations, so as to encourage critical thinking by the student; 3.
H use mathematical procedures such as algebra, statistics, scientific notation, and significant figures to analyze data using the International System (SI) units 2.
D distinguish between scientific hypotheses and scientific theories; 2.
Unlike hypotheses, scientific theories are well-established and highly-reliable explanations, but may be subject to change as new areas of science and new technologies are developed; 2.In many places we see evidence that the Earth's atmosphere had to evolve before living things could live on land.
