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.
Best Answer: . Cirrus Clouds. thin and wispy. The most common form of high-level clouds are thin and often wispy cirrus clouds. Typically found at heights greater than 20,000 feet (6,000 meters), cirrus clouds are composed of ice crystals that originate from the freezing of supercooled water droplets. Cirrus generally occur in fair weather and point in the direction of air movement at their elevation. Source(s): http://ww2010.atmos.uiuc.edu/(Gh)/guides... A cirrus cloud is a type of cloud composed of ice crystals and characterized by thin, wisplike strands, often accompanied by tufts. Sometimes these wispy clouds are so extensive that they are virtually indistinguishable from one another, forming a veil or sheet called cirrostratus.
