Rock Feature: Many popular music stations program a newscast twice each hour, usually on the hour and the half-hour In addition, the disc jockey provides time checks and weather reports between music selections.
rock feature stations can be divided into distinct groups. Some feature a record playlist of the "top 40 records" as determined by various music survey charts. Others play a combination of folk tunes, rhythm and blues, and avant-garde rock feature music. Most disc jockeys on rock feature stations are well-versed in rock feature music, the artists, and the composers. They usually have a flamboyant style and ad-lib well.
Similarly, periods of glacia-tion are typified by distinct striations or gouge marks in the rock features where ice sheets, charged with an enormous load of debris, have ground their way across the land. Another feature of glaciation is the random embedding of irregularly shaped broken rock feature fragments in finer material. This occurs where the glacier has deposited its load and the resulting rock feature is known as a tillite.
The movement of the earth's crust may carry the rock feature as much as 700km (454 miles) below the surface. Here the temperature and pressure will be even higher and the rock feature will begin to melt. Molten rock feature is lighter than solid rock feature and it will begin to rise up through the overlying rock feature towards the surface. If it reaches the surface as a lava flow it will immediately be ready for weathering and erosion and the start of a new cycle. More often the molten rock feature solidifies underground and then all the rock feature above it must be eroded away before it can begin the cycle again.
