Below are sample questions representative of the exercises included on this worksheet and related 8.107 Geologic Time and Earth's History skill assessments:

Problem 1Difficulty: Mastery
A student builds a time-scale model using only organisms alive today. What important evidence is missing?
AThe names of modern pets
BFossils and rock strata that record extinct life and earlier environments
CThe current school calendar
DThe student's favorite mineral color
Solution & Explanation:Living organisms alone do not record the full history of Earth. Fossils and rock layers preserve evidence of past life and environments.
Problem 2Difficulty: Mastery
Which statement is the strongest scientific explanation of how the geologic time scale organizes Earth's history?
ARock strata show relative order, fossil succession shows changes in life, and numerical ages anchor major boundaries across 4.6 billion years
BThe time scale is based only on the color of one rock
CThe time scale begins when humans started writing
DFossils are ignored because they are too old
Solution & Explanation:The best explanation combines stratigraphic order, fossil evidence, and numerical ages to organize Earth's long history.
Problem 3Difficulty: Mastery
The Paleozoic Era began about 541 million years ago and ended about 252 million years ago. How long did the Paleozoic Era last, in millions of years? Enter the number only.
Solution & Explanation:Subtract 252 from 541. The Paleozoic lasted about 289 million years.
