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.
a warm front has/brings nice warm weather. Warm fronts most often bring cloud weather with light to moderate snow flurries or rain showers. Thunderstorms can occur, but not often. Before the warm front passes, the temperature is cool with significant precipitation (depending on geography) such as rain or snow or sleet. While the front passes, the temperature warms suddenly with light precipitation. Afterwards, the temperature remains warm with little or no precipitation and few clouds.
