Answer:
1- SLEET
2- HAIL
3- RAIN
4- FREEZING RAIN
5- SNOW
Explanation:
(1) Sleet- Sleet refers to the type of rain that forms very small ice crystals as it falls from the cold air. This cold air provides a much cooler temperature favoring in the formation of these crystals.
(2) Hail- When the ice pellets are allowed to scatter within the dense cloud, then the ice pellets combine with the water droplets present at a higher altitude. It then grows larger in size, and after this continuous motion of ice pellets, they fall back on the surface.
(3) Rain- It is the most commonly occurring precipitation and these raindrops are formed when the ice crystals in the clouds are melt.
(4) Freezing Rain- These are raindrops that usually gets freeze as they fall over the surface in a comparatively colder weather. After precipitation, the surface gets covered by these ice coatings.
(5) Snow- The ice crystals when it grows and gets accumulated in the clouds, they form snowflakes that are of variable shapes and sizes.
Hence the correct answers are being matched.
Crop rotation
this ensures that one plot of soil is getting all of the nutrients from every fruit or vegetable, instead of just one.
