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.
Next time, youâll be able to correct them. While itâs true that clouds contain water, they actually arenât made of water vapor. If they were, you wouldnât be able to see them. The water that makes up clouds is in liquid or ice form. The air around us is partially made up of invisible water vapor. Itâs only when that water vapor cools and condenses into liquid water droplets or solid ice crystals that visible clouds form. A cloud on a sunny, fair-weather day.
