Earth Science & Earth and Space Sciences Regents Practice & Study Guide
Taking the Regents in 2027? Earth Science has been replaced by the new Earth & Space Sciences Regents, but the core content is the same. No Regents exam depends on a reference document more than Earth Science: the Earth Science Reference Tables (ESRT) are the answer key to a huge fraction of the exam, if you know where to look. RegentsLab's Earth Science bank has hundreds of real past-exam questions with worked solutions that walk through the exact ESRT chart each answer comes from.
What's on the Earth Science Regents
RegentsLab organizes its Earth Science question bank into the units below — the same structure the exam draws from:
- Earth Tools & Measurement
- Rocks & Minerals
- Dynamic Earth
- Geologic History
- Weather & Climate
- Energy & Atmosphere
- Water Systems
- Astronomy
Weather, astronomy, and plate tectonics (Dynamic Earth) are the heavyweight units on nearly every administration.
Exam format
The written exam runs 3 hours with multiple-choice and constructed-response sections, and the traditional course also includes a separate laboratory performance component. The new Earth & Space Sciences Regents (which replaced Earth Science) is aligned to the NYSSLS standards; the units below are the core content on both.
How to practice
Drill real past-exam questions topic by topic — every question includes a full worked solution. Complete exam simulations for Earth Science are being added; the question bank is live now. Start in the practice lab, and keep the official reference materials open beside you — building fluency with them is part of the preparation.
Frequently asked questions
What are the Earth Science Reference Tables?
The ESRT is an official packet of charts and maps — rock identification, weather symbols, planetary data, geologic history, and more — provided during the exam. Many questions are direct ESRT lookups, so fluency with it is the single biggest score lever.
What score do you need to pass the Earth Science Regents?
A scaled score of 65, combining the written exam with the laboratory component under the traditional format.
What topics are on the Earth Science Regents?
Mapping and measurement, minerals and rocks, plate tectonics and earthquakes, geologic history, meteorology, climate, insolation and energy, the water cycle, and astronomy.
Is the Earth Science Regents being replaced?
Yes. It has been replaced by the new Earth & Space Sciences Regents, aligned to the NYSSLS standards; the 2027 schedule lists only Earth & Space Sciences. The core content overlaps substantially, so real past Earth Science questions are still strong practice.
Is the Earth Science Regents hard?
It has one of the broadest syllabi, but it's also one of the most predictable exams — the same question archetypes recur every year, which is exactly what practicing real past questions trains you for.
