Astronomy and Earth in Space
Module overview →- How do Earth's rotation and revolution explain the apparent daily and yearly motions of the Sun, Moon and stars?Explain Earth's rotation and revolution, the evidence for each, and how they produce the apparent daily motion of celestial objects at 15 degrees per hour, including the use of Polaris to find latitude.11 min answer →

- Why does New York have seasons, and why is the Sun higher and the day longer in summer?Explain how the tilt of Earth's axis and its revolution change the angle and duration of insolation through the year, producing the seasons, the solstices and the equinoxes.11 min answer →
- How do stars differ, what powers them, and what is the evidence for the Big Bang?Use the Luminosity and Temperature of Stars diagram to classify stars, describe the Sun and nuclear fusion, and state the evidence for the Big Bang (red shift and cosmic background radiation).10 min answer →
- What causes the phases of the Moon, eclipses and the tides?Describe the phases of the Moon, solar and lunar eclipses, and the tides as consequences of the motions and gravitational interactions of the Earth, Moon and Sun.10 min answer →
- How are the planets organized, and how does distance from the Sun affect a planet's orbit?Describe the structure of the solar system and use the Selected Properties of the Planets table and Kepler's laws to relate a planet's distance from the Sun to its period and orbital velocity.10 min answer →

- What natural resources do we depend on, and how do we use them without using them up?Describe Earth's key natural resources (water, soil, minerals, air, forests) and explain how resource management, conservation and sustainability balance human needs against the limits of Earth's systems.12 min answer →
- How does carbon move through Earth's systems, and how do humans change that flow?Describe how carbon cycles among the atmosphere, biosphere, hydrosphere and geosphere through photosynthesis, respiration, decomposition and combustion, and explain how human activities alter the carbon cycle.12 min answer →
Geologic History and Dating
Module overview →- How do fossils help us match rock layers and read the history of life?Explain how fossils form, what index fossils are, and how fossils are used to correlate rock layers between distant locations and to infer past environments, using the Reference Tables.12 min answer →
- How do we put a number of years on a rock or fossil?Explain radioactive decay and half-life and use the Reference Tables Radioactive Decay Data to calculate the absolute age of a sample from the ratio of remaining radioactive isotope to its decay product.12 min answer →
- How do we work out the order of events in the rock record without knowing exact ages?Apply the principles of relative dating (superposition, original horizontality, cross-cutting relationships, inclusions and unconformities) to order events in a sequence of rock layers.12 min answer →
- What does the rock record tell us about New York's own deep past?Use the Reference Tables Geologic History of New York State and the bedrock map to read New York's tectonic and environmental history, including ancient mountain-building, shallow seas and the most recent glaciation.12 min answer →
- How is the vast span of Earth's history organized, and what does the time scale record?Describe how the geologic time scale is divided (eons, eras, periods, epochs), how its boundaries mark major changes in life, and use the Reference Tables geologic time scale to read ages and events.12 min answer →
Surface Processes: Weathering, Erosion and Deposition
Module overview →- Why does moving water drop its sediment, and in what order do particles settle out?Explain how deposition occurs as transporting agents lose energy, and use the Reference Tables relationship of particle size to water velocity, together with particle size, shape and density, to predict settling order and sorting.12 min answer →
- What moves weathered material across Earth's surface, and how can we tell which agent did it?Identify the agents of erosion (running water, glaciers, wind, waves and gravity) and use the characteristic shapes and deposits of sediment to infer which agent transported it.12 min answer →
- What makes one landscape a mountain and another a plateau, and how do New York's regions differ?Explain how landscapes are classified (mountains, plateaus, plains) by elevation, relief and structure, how climate and bedrock control landscape development, and use the Reference Tables map of New York's landscape regions.12 min answer →
- How do streams shape the land, and how do we read gradient and elevation from a topographic map?Describe stream behavior and drainage patterns, and use topographic (contour) maps with the Reference Tables gradient equation to calculate gradient, determine stream flow direction and read elevations.13 min answer →
