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.
The sun is also the main contributing factor as to why clouds often, but not always, appear to be white. First, letâs talk about the composition of a cloud. Clouds are composed of tiny round water droplets, which form when water vapor condenses from a gas to a liquid. Next is the electromagnetic spectrum. The sun emits energy over a wide rangem and humans aren't able to see most of that energy with the naked eye.
