Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the number of known phases?At least nineteen distinct crystallographic phases of ice have been identified
2. What is ice and how does it form from water?Ice is the solid form of water. It forms when liquid water cools below 0°C (32°F) at normal pressure. The water molecules arrange into a hexagonal crystal pattern called ice Ih.
3. Why are there so many different kinds of ice on Earth and in space?Scientists have found at least nineteen different crystal forms of ice. Each form appears under specific temperatures and pressures. In space, a type called low‑density amorphous ice is thought to be the most common kind of ice.

Crystalline Structure: The ordered, repeating arrangement of atoms or molecules in a solid material.
Amorphous Solid: A solid in which the atoms or molecules are not arranged in a regular, repeating pattern.
Macroscopic Quantum Phenomena: Quantum mechanical effects that are observable on a large scale, not just at the atomic level.
