Morning sun melts frost on grassy field - Timelapse

In northern climates such as here in Quebec, Canada, it is not uncommon for a grassy field to be covered in dew, and then frost on a cold fall morning.

Frost typically occurs on cold, clear nights when atmospheric conditions cause objects, including grass, to become colder than the surrounding air. Depending on the conditions, frost can be light and scattered or heavy enough to kill annual plants and cause perennial plants to go dormant.

Grass blades move water through them for nourishment, but this moisture can freeze inside the grass ​during a frost. However, a light frost generally doesn't freeze the ground. Frost over several nights can lead to visible signs of damage, depending on the grass species. The dead grass will eventually become thatch that nourishes the soil below as the new seeds germinate and grow.
