Explanation: forming dew, frost, rain and snow

Water - the basis of life on planet Earth. Its cycle in nature makes you think about how dew formed, frost, rain and snow. Changes in temperature and pressure contribute to the rapid crystallization of the particles of the liquid. And the morning coolness causes formation of drops on the grass. The movement of the wind affects the changing of winter and summer. So we are seeing the emergence of thunderstorms and snowflakes.

Shower

Considering the question of forming dew, frost, rain and snow, you should familiarize yourself with every natural phenomenon. The surface of the water in the afternoon heated the sun's rays. There is a constant evaporation of moisture, even in cold weather. Minute particles of liquid upward. They meet with the cold layers of air.

Cooling down, the particles are connected, and the formation of clouds. It moves under the influence of wind over the surface of the earth. It gradually cools down, it turns blue. Water molecules become closer to each other until they connect into a drop. It freezes and is already becoming heavy, falling down. So begins a summer rain.

They reach a certain height where the air is much warmer, the crystal begins to melt. Summer rain getting stronger, the longer continued the evaporation of water and accumulation of its particles in the sky.

Fog

Studying airborne particles, you can further understand how to form dew, frost, rain and snow. One such phenomenon is the fog. He is a failed climb up the cloud when, because of weather conditions, the upper layers are cold enough. Through evaporation can not break through, and the temperature above the surface is still not enough to form drops.

Fog is often formed in the morning hours, the temperature above the surface at this point is omitted. The air becomes cold, and a couple is not able to climb high. Ponds, lakes and rivers continue to cool down, giving heat to the water molecules in the surrounding space.

When the air is gradually heated, the particles couple to either rush up or settle on the grass. So there are drops of dew. Because often we only see them at dawn. The fog accumulates in a hilly area, where there are ravines, gorges, lowlands.

Drops on the plants at dawn

All experienced the phenomenon when every morning dew appears on the leaves of grass, trees, and other plants. Deposited droplets are the result of the continuous movement of water in nature. This comes at a time when the sun has already begun to heat the upper layers of air. As a result, the condensate becomes heavier and descends gently.

When it accumulates near objects, plants, drops of dew. Even items left in the street this morning to get wet.

The Formation of dew is preceded by a day with clear weather, when the sky no suspended water particles. In such conditions there is the greatest evaporation from the surface of the earth. Drops on the plants can be seen only in warm weather. In the winter they turn into ice, called frost.

Winter snowflake

Precipitation from clouds in the form of crystals, which is a patterned flakes called snow. Natural phenomenon refers to the water cycle in nature. Snowflakes are composed of fresh water, only in the modern world, they are not always clean. In the air near the megacities present pollution, which join the particles of the liquid during freezing.

The Crystals during the planning of heaven gradually increase in size. In the winter we see on the ground a huge number of snowflakes. When the frost is strong enough, they do not melt and can be a good look every single bit of it.

Researchers noticed that snowflakes always observed regular geometric shapes: they are six-pointed, the angles between the edges are the same, but drawing them is always different. These data were obtained when examining crystals under a microscope. Specific crunch when pressed on the snow in cold weather is associated with the destruction of ice.

The Castle

To learn how to form dew, frost, rain and snow, you need to familiarize yourself with the process of the formation of hail in the sky. Often this phenomenon is observed in the summer in hot weather. The mechanism of formation of ice balls is associated with cold air flow occurring with the heated lower layer.

To understand the principle of the formation of hail, the researchers sawed ball of ice and saw a heterogeneity of structure. Layers differ in color and density. At the highest point of the atmosphere the particles of the vapor immediately freezes, no time to turn into drops. Under the action of gravity begin to fall, acquiring the surrounding molecules of the liquid.

Flying through a cloud, ice become harder, further, heat flow is melting of the upper layers of the ball. But hradynky very quickly fly down and do not have time to fully melt. Therefore, they turn out to be so smooth.

Frost

When in the street a strong frost, frost may form on the morning of fog, rising into the night. In the afternoon there is an active evaporation of water from the surface of the earth under the action of the rays of the sun. The frost on the branches of trees formed from the freezing of the upper layers of the atmosphere, when the water particles are not able to rise up. The phenomenon precedesclear and dry frosty weather.

Not always on the ground lies the snow, the frost appears due to the cold snap. The mechanism of water movement similar to that observed in the rain, only the whole cycle happens at a low altitude. Clouds are not formed, the selected condensation quickly turns into icicles.
