See how Kuest teaches it

It asks before it tells, so you do the thinking and it sticks.

You: Why do we have seasons?
Kuest: What's your first guess? What changes about Earth over the year that could make summer warmer than winter?
You: Earth is closer to the Sun in summer and farther away in winter.
Kuest: That's the most common guess, so it's worth checking. Earth is actually closest to the Sun in early January, during winter in the US. And when it's summer here, it's winter in Australia. What could explain opposite seasons in the two hemispheres?
You: The tilt? One half is tilted toward the Sun while the other is tilted away.
Kuest: Yes. Earth's axis is tilted about 23.5°. The half tilted toward the Sun gets more direct sunlight and longer days, so it has summer.

Seasons come from Earth's tilt, not its distance from the Sun.

The method

How to study Earth science with Kuest

Earth science mixes big ideas like plate tectonics with a lot of vocabulary and map reading. Connect each term to a process you can picture, practice reading real maps and diagrams, and review a little across several days.

  1. Start with your own explanationTutor chat

    Kuest asks what you already think, like why we have seasons, and builds from there so misconceptions get fixed, not memorized.

  2. Watch processes on the boardTeaching board

    See plate boundaries, the rock cycle or Earth's orbit drawn step by step, with simple simulations for moon phases and tilt.

  3. Snap maps and diagramsSnap a photo

    Photograph a topographic map, weather map or rock-layer diagram and learn to read it by answering questions about it.

  4. Lock in vocabularyFlashcards

    Turn minerals, rock types and weather terms into flashcards that come back on a spaced schedule.

  5. Listen to your notesPodcasts

    Turn a unit into a short podcast to review on the bus or before class.

  6. Quiz yourself before the testQuizzes

    Get unit quizzes with diagram and data questions like the ones on state tests and the Regents exam.
