Question

which led to the dust storms of the 1930s? the use of dry farming the creation of cattle ranches the consolidation of small farms the removal of grass

Explanation:

The Dust Bowl in the 1930s was caused by a combination of factors. Over - cultivation led to the removal of native grasses. These grasses had deep roots that held the soil in place. Without them, the soil became loose and was easily picked up by the wind, creating dust storms. Dry farming (a method of farming in arid regions) was also a contributing factor as it further degraded the soil structure. Cattle ranches and consolidation of small farms were not the main causes compared to soil - grass interaction.

Answer:

the use of dry farming, the removal of grass
