I WONDER - What Is Frost?

Frost forms when the temperature drops below freezing, specifically below 30°F or 0°C, which is the freezing point of water. When the air becomes this cold, moisture in the air turns into ice crystals that attach to surfaces like windows, leaves, and the ground.

What temperature does the air need to fall below for frost to form?

At what temperature in Fahrenheit does frost typically occur?

What is the freezing point of water in degrees Celsius?

What happens to the moisture in the air when the temperature gets cold enough?

What are the physical forms that frost can take on surfaces?
