Elements

Sand
Falls and piles up. Sinks through water and oil.
Salt
Falls like sand and dissolves into water it touches. Boil the salt water and the salt comes back. Salt melts ice.
Stone
Stays where you draw it. Acid wears it away slowly.
Wood
Stays where you draw it and burns for a long time. Water puts it out.
Plant
Grows into fresh water it touches, but not into salt water. Burns quickly.
Ice
Slowly freezes the fresh water around it. Melts near fire, lava and steam, and under salt.
Water
Flows and levels out. Puts out fire and boils into steam.
Oil
Floats on water and burns fiercely. Water does not put burning oil out.
Acid
Sinks through water and eats almost everything else, getting used up as it goes. Stone holds out longest.
Lava
Creeps along and sets things on fire. Where it meets water it hardens into dark stone and throws off steam.
Fire
Flickers upward and burns out fast, lighting wood, oil and plants and leaving smoke. Draw it over wood to light it.
Smoke
Drifts up and thins away.
Steam
Rises, bubbles up through water, and condenses back into water as it cools.
