Frozen
water

Ice is simply water that has frozen.

When water gets cold enough, its molecules slow down and arrange themselves into a solid structure.

Ice is solid, cold, and usually clear or white.

Forms of ice

Icicles

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

Frost is a thin layer of ice crystals that forms on cold surfaces like grass, flowers, windows, cars, or leaves usually overnight.

Sea Ice

Sea ice is frozen ocean water that forms in cold regions, mainly near the North and South Poles.

Dry Ice

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.

Ice in nature


Ice plays a crucial role in Earth’s climate. Polar ice caps and glaciers reflect a large portion of incoming sunlight back into space, a process known as the albedo effect. This reflection helps keep the planet cooler by reducing the amount of heat absorbed by Earth’s surface.

Moreover, as global temperatures rise and ice melts, the Earth's albedo decreases, leading to even more heat absorption. This process disrupts global weather patterns and ocean currents.
Ultimately, the preservation of ice is essential for ecological balance.


Properties

Chemical formula: H₂O
State of matter: Solid
Color: Transparent Chemical formula: H₂O State of matter: Solid Color: Transparent Melting point: 0°C Crystal structure: Hexagonal

Why ice floats?

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

Facts

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.

It's just a tip of the iceberg...
