<h2>Clouds on Venus</h2>

<p>After a quick search, it appears the <a href="http://www.universetoday.com/36871/clouds-on-venus/" rel="nofollow">clouds found on Venus</a> are different than Earth's:</p>

<blockquote>
  <p>Venus is covered by a thick layer of clouds. These clouds are made
  mostly of sulfuric acid and are very fast moving, going up to 220
  miles per hour (350 km per hour). The clouds rotate 60 times faster
  than the planet rotates. The clouds circle Venus in four Earth days;
  the planet rotates around its axis in 243 Earth days. These
  quickly-moving clouds distribute the heat around the planet, making
  the night side hot also. V-shaped cloud patterns are visible in the
  middle latitudes when the clouds are examined in ultraviolet light.
  The clouds rain sulphuric acid (extremely acid rain), but this
  corrosive precipitation does not reach the surface. The high heat
  beneath the clouds (up to 220°C) evaporates the rain drops about 10
  miles (30 km) above Venus. <a href="http://www.enchantedlearning.com/subjects/astronomy/planets/venus/venusatmosphere.shtml" rel="nofollow">SOURCE</a></p>

Can the clouds on Venus and Titan be categorized in the same way as clouds on Earth?
