Timed Earth and Space Science Quiz

Timed Earth and space science inside a mixed quiz

Earth-science records cover rocks, tectonic plates, the asthenosphere, mid-ocean ridges, condensation, the geodynamo, the Moho, and tides. Space questions range from Earth's orbit and lunar eclipses to planetary winds, Kepler's laws, electromagnetic radiation, and cosmological redshift. These prompts are mixed with biology, chemistry, and physics rather than isolated in a separate mode, so the visible category label helps the player switch scientific context.

Four five-question experiment clocks

The timer starts only after the first answer or hint in an experiment. Easy allows 76 seconds, medium 66, and hard 56 for each group of five. Correct answers award remaining-time and streak bonuses; a wrong answer removes forty points, resets the streak, and consumes one of three lives. Unused time becomes an experiment-clear bonus before the next clock resets.

Hints preserve the scientific choice

H or Hint outlines the supported answer for 1.6 seconds but never selects it. Easy provides four hints, medium three, and hard two across all twenty questions. Pause freezes an active clock, and Restart creates a fresh order at the selected level. The result is a self-contained single-player challenge, not a claim of live opponents or multiplayer rooms.
