Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the scientific field?Paleoseismology
2. What is the primary data sources?Geologic sediments and rocks exhibiting evidence of seismic displacement
3. How do scientists find evidence of ancient earthquakes?They dig trenches across fault lines or in places where layers of sediment have piled up. In the trench, they look for broken layers, landslides, or special sand shapes that show the ground moved.
4. Why is paleoseismology important for cities?It tells us how often big earthquakes happen in an area. Knowing this helps builders make stronger houses, bridges, and dams that can stand up to future shaking.

Paleoseismology: The study of prehistoric earthquakes through the analysis of geological evidence preserved in the Earth's crust.
Stratigraphy: The branch of geology concerned with the study of rock layers (strata) and layering, especially the formation, relation, and interpretation of strata.
Seismic Hazard Assessment: The scientific process of estimating the probability and intensity of future earthquakes in a given geographic area.
Geochronology: The science of determining the age of geological materials and events, often using radiometric dating techniques.
