Volcanoes and Wetlands: Earth's Extremes
Like Duolingo, but for Volcanoes and Wetlands: Earth's Extremes. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
For the part of you with thirty open tabs that never became anything.
18 levels across 3 sections, about 36 minutes end to end, roughly 7 days at five minutes a day. It moves through Reading the Active Landscape, Life on the Edge, and Global Systems and Cycles. It assumes you already know the basics.

Key ideas in Volcanoes and Wetlands: Earth's Extremes
- Low-viscosity basaltic lava flows easily over long distances to create gentle slopes
- Shield volcanoes like Mauna Loa lack the explosive, sticky magma of stratovolcanoes
- Steep-sided stratovolcanoes are built from thick, viscous andesite or dacite
- Pyroclastic flows leave behind unsorted, fragmented deposits called ignimbrites
- Basaltic flows are characterized by distinct textures like ropey pahoehoe
- Explosive eruptions produce fragmented tephra rather than continuous flows
- Distinguishing shield volcanoes from stratovolcanoes by slope angle and lava viscosity
- Identifying pyroclastic flow deposits versus slow-moving basaltic lava in the field
- Craters are small vents formed by outward explosions during an eruption
- Calderas are massive depressions formed when the ground collapses into a void
- A caldera's diameter is significantly larger than the individual vents within it
- The Law of Superposition dictates that deeper tephra layers are older
- Recognizing the footprint of a caldera compared to a standard crater
- Distinctive ash 'marker beds' allow geologists to sync dates across regions
- Soil development between ash layers indicates dormant periods between eruptions
- Using tephra layers in soil to date local geological history

Eight weeks. You meant to finish. You didn't.
Tomo gives Volcanoes and Wetlands: Earth's Extremes the Duolingo treatment: levels, streaks, and quick quizzes that test what you just learned. That game loop is what the tabs above never had, so it's the one you actually finish.
Here's what playing it feels like
A real question from this course. Take your best guess.
Why is a shield volcano like Mauna Loa shaped so differently from a pointy, explosive one?
