Sample Practice Problems

Preview the types of problems and questions covered in this worksheet

Below are sample questions representative of the exercises included on this worksheet and related 9.100 Earth Formation and Early History skill assessments:

Problem 1Difficulty: Mastery

Use the final synthesis table. Which conclusion is best supported by the complete set of evidence?

AOne young lava flow gives the complete age of Earth.

BPlanetary surfaces outside Earth cannot inform any question about early Earth.

CEarth's early history is reconstructed from incomplete solar-system and rock evidence.

DEarth's earliest history is unknowable because no single perfect rock remains.

Solution & Explanation:The table shows converging evidence with limitations. A strong conclusion recognizes that the record is incomplete but still scientifically useful when multiple lines of evidence agree.

Problem 2Difficulty: Mastery

Which statement is the best reason to include both meteorites and ancient Earth materials in an explanation?

AThey always contain the same minerals in the same amounts.

BMeteorites record early solar-system conditions, while ancient Earth materials record surviving clues from Earth's own early crust.

CUsing two sources makes evidence unnecessary.

DAncient Earth materials are never altered, and meteorites are always from Earth.

Solution & Explanation:The two evidence sources answer different parts of the problem. Meteorites constrain early solar-system conditions, and ancient Earth materials provide direct but incomplete Earth evidence.

Problem 3Difficulty: Mastery

Use the sample-source map. Which sampling plan would best reduce bias when studying early lunar impact history?

AUse only photographs and forbid any sample analysis.

BChoose samples only by the color that looks brightest.

CCollect all samples from the rim of one basin only.

DCollect dated samples from several basins and highland regions across the near side and far side.

Solution & Explanation:Sampling many regions reduces the chance that one basin or local process dominates the age pattern. Diverse sample locations improve the explanation.
