Icicles are long, pointy pieces of ice that hang down, usually from roofs, gutters, tree branches, or cliffs. They form whens now or ice melts.
Frost is a thin layer of ice crystals that forms on cold surfaces like grass, flowers, windows, cars, or leaves usually overnight.
Sea ice is frozen ocean water that forms in cold regions, mainly near the North and South Poles.
Dry ice is frozen carbon dioxide. It’s extremely cold and turns directly from solid into gas (no liquid), creating a thick, fog-like mist.
Chemical formula: H₂O
State of matter: Solid

Chemical formula: H₂O
State of matter: Solid
Color: Transparent
Melting point: 0°C
Crystal structure: Hexagonal
When water freezes, molecules form a rigid hexagonal structure This structure takes up more space, lowering density Floating ice insulates water below, allowing life to survive in cold climates
Ice can slowly flow like a thick liquid in glaciers due to gravity. The air trapped inside ice can tell scientists about Earth’s past climate. Ice expands by about 9% when water freezes. It is less dense than its liquid form.
