Earth Science Prompts

Practice identifying trophic levels, distinguishing a food chain from a food web, and calculating energy loss with the ten percent rule.

Practice identifying Earth's internal layers by composition and by physical behavior from depth, state, or seismic-wave clues, then check answers against the exact clue.

Practice classifying energy sources as renewable or nonrenewable based on replenishment rate, including tricky cases like nuclear and biomass, with reasoning for each answer.

Practice identifying minerals using streak color, luster type, and cleavage or fracture pattern together, weighted the way a geologist actually would, or check an identification.
