Question

Чому безсніжними зимами озимина потерпає від морозів? Чому влітку вода в річці на глибині холодніша, ніж на поверхні? Чому навесні забруднений сніг тане швидше, ніж чистий?

Answer 1

Це пов'язано з теплопровідністю,коли в зимку є сніг то він утримує тепло в землі і не дає їй замерзнути.Сніг є білий і нювін відштовхує світло ,а коли він забруднений то стаєбільш темнішим а як відомо темні кольори поглинають непло і тому віш швидше тане

Answer 2

Why does winter wheat suffer from frost during snowless winters?

Winter wheat can suffer from frost during snowless winters due to several reasons. One of the main reasons is that snow acts as an insulating layer, protecting the plants from extreme cold temperatures. When there is no snow cover, the soil and plants are more exposed to the freezing temperatures, which can damage or kill the wheat plants.

Snow cover helps to regulate the temperature of the soil and provides insulation against the cold air. It acts as a protective blanket, preventing the soil from freezing deeply and maintaining a more stable temperature. Without snow cover, the soil can freeze more deeply, affecting the roots of the wheat plants and making it harder for them to absorb water and nutrients.

Additionally, snow cover also helps to retain moisture in the soil. When there is no snow, the soil can become drier, which can further stress the wheat plants and make them more susceptible to frost damage.

It's important to note that while snow cover can provide protection against frost, excessive snowfall can also have negative effects on winter wheat. Heavy snow can lead to snow mold diseases and can cause physical damage to the plants if it accumulates too heavily.
