Apr 22, 2024 · VIENNA— Samples of eerie blue glacial ice from Antarctica are a staggering 6 million years old, scientists announced last week, doubling the previous record for Earth’s oldest ice. The ice opens a new window on Earth’s ancient climate—one that isn’t exactly what scientists expected.
Ice is water that is frozen into a solid state, typically forming at or below temperatures of 0 °C, 32 °F, or 273.15 K.It occurs naturally on Earth, on other planets, in Oort cloud objects, and as interstellar ice.As a naturally occurring crystalline inorganic solid with an ordered structure, ice is considered to be a mineral.Depending on the presence of impurities such as particles of soil or bubbles of air, it can appear transparent or a more or less opaque bluish-white color..

Ice. Ice is the common name for frozen water. Other liquids, such as ammonia or methane or milk, are called 'milk ice', for instance, instead of just 'ice'. Liquid water becomes solid ice when it is very cold. The freezing point is 0° Celsius (32° Fahrenheit or 273 kelvin ). Ice can be made in a home refrigerator or freezer.

Jun 1, 2024 · ice, solid substance produced by the freezing of water vapour or liquid water. At temperatures below 0 °C (32 °F), water vapour develops into frost at ground level and snowflakes (each of which consists of a single ice crystal) in clouds.
Oct 19, 2023 · Vocabulary. Ice is water in its frozen, solid form. Ice often forms on lakes, rivers and the ocean in cold weather. It can be very thick or very thin. It occurs as frost, snow, sleet and hail. Water will freeze at zero degrees Celsius (32 degrees Fahrenheit).
