Cloud categories. (Hands-On Activity).Clouds are categorized by their height in the troposphere troposphere: see atmosphere. troposphere Lowest region of the atmosphere, bounded by the Earth below and the stratosphere above, with the upper boundary being about 6–8 mi (10–13 km) above the Earth's surface. (atmospheric layer closest to Earth's surface Noun 1. Earth's surface - the outermost level of the land or sea; "earthquakes originate far below the surface"; "three quarters of the Earth's surface is covered by water" surface ) and their appearance. The three basic categories are low-, middle-, and high-level clouds. Clouds at different altitudes don't just look different--they are different. Find out how. You Need: pencil * pen * color pencils (dark gray, light gray, light blue) * eraser * research material on clouds (from library or Internet) * "Global Warming global warming, the gradual increase of the temperature of the earth's lower atmosphere as a result of the increase in greenhouse gases since the Industrial Revolution. : Cloud Patrol" (p. 21) To Do: 1. Review "Global Warming: Cloud Patrol" (p. 21). 2. Select two low-, two middle-, and two high-level clouds. 3. Research the altitude, composition, and temperature of each cloud. 4. Draw the clouds on the space provided below. Color-code each cloud: low-level, dark gray; medium-level, light gray; high-level, light blue. 5. Beside each cloud, label its temperature and composition. [ILLUSTRATION OMITTED] Conclusions: Which cloud could drizzle all day? Which one is associated with thunderstorms thunderstorms a storm characterized by thunder and lightning caused by strong rising air currents; identified as agents of animal disease because of their involvement causing (1) spasmodic colic; (2) lightning strike; (3) injuries of cattle acquired in stampedes initiated by storms. ? What kind of cloud appears feathery feath·er·y adj. 1. Covered with or consisting of feathers. 2. Resembling or suggestive of a feather, as in form or lightness. feath ? Why? Don't Stop Now! Research contrails, and write a paragraph explaining how they're formed. Then draw one in the space above. Bonus: What is a cloud on the ground called? ANSWERS Drizzle accompanies nimbostratus clouds. Cumulonimbus cumulonimbus: see cloud. clouds produce thunderstorms. Cirrus clouds look feathery because they're wisps of ice. Contrails form around the exhaust of high-flying jets. Bonus: Fog is a cloud on the ground. |
