01

Climate at the reference point

Reykjavík is classified as Cfc in the temperate climate family. Explore how temperature and rainfall define this pattern.

Explore the model 02

Hotspots

Follow a moving plate over a volcanic source and see how an island chain can record its motion.

Explore the model 03

Seafloor spreading

See how new oceanic crust forms as plates separate, and how magnetic stripes preserve that history.

Explore the model 04

Plate boundaries

Compare plates moving apart, sliding past each other and converging. What landforms would each movement produce?

About the climate and map data

Climate labels describe the marked reference point using the 1991–2020 Köppen–Geiger classification; climate can vary greatly within the surrounding country or region. Tectonic labels identify regional teaching examples.

Beck et al. climate data (CC BY 4.0) and Bird’s PB2002 plate model provide the scientific context.
