## Step1<br />The first question is about the services formed by the federal government due to the Dust Bowl. The Dust Bowl was a period of severe dust storms that greatly damaged the ecology and agriculture of the US and Canadian prairies. The Soil Conservation Service was formed to address these issues.<br /><br />## Step2<br />The second question asks why fire is considered a common management practice. Fire is used as a tool in forest management to suppress invasive species such as shrubs and trees.<br /><br />## Step3<br />The third question asks for a reason that is NOT why cover crops are important. Cover crops provide shade to the main crops, prevent soil erosion, increase water retention, and provide habitat for spiders to eat crop pests. However, they do not provide shade to the main crops.<br /><br />## Step4<br />The fourth question asks about the agricultural practice that ensures an area is NOT overgrazed by moving cattle from pasture to pasture. Rotational grazing is the practice where livestock are moved between different pastures, which prevents overgrazing.<br /><br />## Step5<br />The fifth question asks about the percentage of the proceeds from the Duck Stamp Act that is provided for wetland and waterfowl habitat acquisition. The Duck Stamp Act provides 98% of its proceeds for wetland and waterfowl habitat acquisition.<br /><br />## Step6<br />The sixth question asks about the primary use of tillage. Tillage is primarily used to control weeds and aerate soil.<br /><br />## Step7<br />The seventh question asks about the typical location of grasslands. Grasslands typically exist between forests and deserts.<br /><br />## Step8<br />The eighth question asks about the permanence of topsoil loss. It is true that the loss of topsoil is fairly permanent because the process to create just a few centimeters of topsoil takes about 1,000 years.
