Points to Remember. 1  Marijuana refers to the dried leaves, flowers, stems, and seeds from the hemp plant, Cannabis sativa. 2  The plant contains the mind-altering chemical delta-9-tetrahydrocannabinol (THC) and other related compounds. 3  People use marijuana by smoking, eating, drinking, and inhaling it.
A cold front is symbolized on a weather map as a line with triangles. The triangles can be thought of as icicles. Cold fronts are often coloured blue. The presence of a cold front means that cold air is advancing and pushing underneath warmer air.
Describe the frontal lifting patterns for a cold front and then a warm front. A cold front causes cumulonimbus clouds and thunderstorms, brief rain showers, and sudden temperature decrease. A warm front causes the warm air to be slowly lifted in a gentle manner, forms stratus clouds, and light continuous precipitation. The cloud progression is nimbostratus to stratus to altostratus to cirrostratus to cirrus.
