What are black blizzards

A black blizzard is a dust storm especially in the dust-bowl area of the U.S.

Explanation:

During most of the 1930s, the Great Plains region was devastated by drought and high winds. Howling across the Great Plains, these winds whipped up the soil of the over-farmed land and created blizzards of dust. These “black blizzards” were so thick and blinding that daylight seemed more like dusk.

Explanation:

the andes or andean mountains (spanish: cordillera de los andes) are the longest continental mountain range in the world, forming a continuous highland along the western edge of south america. this range is about 7,000 km (4,300 mi) long, about 200 to 700 km (120 to 430 mi) wide (widest between 18° south and 20° south latitude), and of an average height of about 4,000 m (13,000 ft). the andes extend from north to south through seven south american countries: venezuela, colombia, ecuador, peru, bolivia, chile and argentina.
