Itâs no secret that certain foods can help you lower your LDL (âbadâ) cholesterol, which causes a buildup of plaque in the arteries that leads to heart disease, heart attacks, and stroke.
Poor farming practices. Once the earth had been farmed and not enough nutrients were in the soil to continue farming the soil became dry. Dry soil promoted a drought. Without â¦ water the loose soil caused by farming became very easy for the wind to pick up. All of these combined conditions led to the dust bowl. Lack of rain.
Sandstorms -- also called duststorms -- are caused by strong winds blowing over loose soil or sand, and picking up so much of that material that visibility is greatly reduced. The widespread abundance of loose sand in deserts makes them the most common locations for sandstorms to form. In desert regions at certain times of the year, sandstorms become more frequent because the strong heating of the air over the desert causes the lower atmosphere to become unstable. This instability mixes strong winds in the middle troposphere downward to the surface, producing stronger winds at the surface.
