What are two differences between stratus cloud and cirrus clouds

Stratus clouds have "layers" and look like they've been chopped up into many pieces. They produce Drizzles, and snow grains, and can only go up to an altitude of 6,000 ft. Cirrus cloud are similar to stratus clouds, but they are thinner and spread apart. They start at an altitude of 16,000 ft. I hope this helped ^^
