SHAPING PLANETARY SURFACES

impactcratering: the excavation of bowl-shaped depressions by asteroids or comets striking a planet's surface
volcanism: the eruption of molten rock or lava from a planet's interior onto its surface
magma: underground molten rock
impact basins: very large impacts
micrometeorites: sand-size particles that impact a surface
basalt: relatively low viscosity lava
stratovolcanoes: tall, steep made of viscous lava that flows
volatiles: "evaporates easy"
multiringbasin: ripple effects
erosion: the weathering down or building up of geological features by wind, water, ice and other factors
ejecta: debris from the blast shoots high in the atmosphere than rains down over a large area
lunarmaria: impact basins up to 1, 100 km across
sedimentaryrock: compact form of sediment deposited over time
shieldvolcanoes: viscous basalt lava solidify before they can completely spread out
tectonics: the disruption of a planets surface by internal stresses
