The matching bolt and nut grades identifying markings are designated differently to demonstrate the strength relationship of the two components. Due to the advent of mass assembly it is an acceptable practice for the matching nut to be the stronger component.
Answers. Best Answer: The altitude and therefore, the temperature, together with the age of the cloud, decides if it is made of ice crystals, water droplets or, both. High clouds only made of ice crystals are called cirrus clouds. Those are the left-overs of strong convection bringing moisture all the way to the tropopause, which is the top of the troposphere. Sometimes, cirrus even escape from the troposphere into the stratosphere.
Snow is produced when liquid cloud droplets in a cloud are lifted above the freezing level and begin to form ice crystals. As it turns out though, even in a cold cloud or the region of a cloud that is below freezing, the cloud is still composed mostly of liquid water droplets.In fact, liquid water droplets still outnumber ice crystals to temperatures as cold as -20C.ot all cloud droplet collisions will result in coalescence, as the strong surface tension of small droplets can resist merging and even cause larger drops to break apart during a collision, but there are still enough large water droplets to produce precipitation in clouds with sufficient vertical growth.
