They named it Jones County after John Paul Jones, the early American Naval hero who rose from humble Scottish origin to military success during the American Revolution. Ellisville, the county seat, was named for Powhatan Ellis, a member of the Mississippi Legislature who claimed to be a direct descendant of Pocahontas.
An avalanche occurs when the stress (from gravity) trying to pull the snow downhill exceeds the strength (from bonds between snow grains) of the snow cover. Four conditions must be present for an avalanche to occur: 1  a steep slope. 2  a snow cover. 3  a weak layer in the snow cover. 4  a trigger.
Landslides. Movements of earth down a steep slope are called landslides. Landslides happen when hills or mountains become unstable. Slopes become unstable when the pieces of rock that form the slopes are not properly supported. Human activities, water, frost and ice can cause landslides.nlike earthquakes and volcanic eruptions that can change landforms in a matter of hours, changes caused by weathering take thousands or millions of years. The speed at which weathering forces work depends a lot on the action of water and the temperature of the area.
