ESS1.C: The History of Planet Earth

Primary School (K-2)

Some events happen very quickly; others occur very slowly, over a time period much longer than one can observe.

Elementary School (3-5)

Local, regional, and global patterns of rock formations reveal changes over time due to earth forces, such as earthquakes. The presence and location of certain fossil types indicate the order in which rock layers were formed.

Middle School (6-8)

The geologic time scale interpreted from rock strata provides a way to organize Earth’s history. Analyses of rock strata and the fossil record provide only relative dates, not an absolute scale.

Tectonic processes continually generate new ocean sea floor at ridges and destroy old sea floor at trenches.

High School (9-12)

Continental rocks, which can be older than 4 billion years, are generally much older than the rocks of the ocean floor, which are less than 200 million years old.

Although active geologic processes, such as plate tectonics and erosion, have destroyed or altered most of the very early rock record on Earth, other objects in the solar system, such as lunar rocks, asteroids, and meteorites, have changed little over billions of years. Studying these objects can provide information about Earth’s formation and early history.
