Standard: 5.8 - Earth Science
Strand: C - Processes that Shape the Earth
- How do
geologic events occurring today provide insight into Earth’s past?
form systems. These systems continually interact at different rates of time,
affecting the shape of the Earth’s surface regionally and globally.
Cumulative Progress Indicator: 2 - The student will show how
successive layers of sedimentary rock and the fossils contained in them can be
used to confirm the age, history, changing life forms, and geology of Earth.
• Interpreting the age, geologic history, and changing life forms, of a sample
cross section of land
• Determining the relative ages of a geologic sequence of rocks, given a variety
of fossils and the layers where they were found
Sample Test Items:
1. Which evidence would be most helpful to scientists in determining the age of
A. a comparison of Earth’s composition to other planets’ compositions
B. soils, fossils, and remnants of mountains
C. sediments, minerals, soils, and size of rocks
* D. fossil records, rock records, and layers of earth
2. Fossils of an animal that only survives in a tropical swamp are found in an
arid (dry) section of northern Canada. Describe three changes that have occurred
since the fossils were living organisms. Be sure to consider possible changes in
life-forms, climate, environment, and geologic features.
