Each of these planting methods were promoted after the Dust Bowl to reduce erosion. Explain how each works.

• Contour Plowing-Plowing along the curves in the land, Water moves slowly along curves instead of straight.

• Strip Cropping- Alternating row crops, with cover crops to ensure that no soil is exposed to wind or water.

• Physical weathering, where the rock is broken apart by wind, and water.

• Terracing-Forming a series of flat stepalong hillsides. Slows down water as it moves downhill.

For each of the macrounutrients, give an example of a food source that contains it.

• Protiens-Animal Products

• Fats-Plant oils

• Carbohydrates-Any plant products

• Furrow-Troughs alongside row crops

What food source is contained in protiens

• animal products

The diferent types of disorders caused by malnourishment

• Kwashikor-cause by lack of protien

• Legumes-cause by lack of nitrogen

• Anemia-cause by lack of iron

• Goiter-cause by lack of iodine.

What happens when you get a Kwashiorkor? What causes it

• Lack of protien-Body cannot produce enough red blood cells.

• Lack of Iodine-The thyroid gland enlarges.

• Lack of protien-water imbalance, causes abdominal swelling.

• Lack of Iodine- symbiotic bacteria that lives in nodules.

Before the green revoulutiong most farmers practiced subsistence agriculture. Nowmost practuace Monoculturing. Whats the difference?

• Substince involves multiple types of food while monoculturing is focussed on one crop

• Substince provides less food while monoculturing provides more.

• Substince is much more food while monoculturing is much less.

• Monoculturing involes multipe foods while substince is foccused on one crop

Furrow description and its efficiency

• Water travels down along row crops-40-60% efficiency

• Tubes directly deliver water-90-95% efficiency

• Water is sprayed around a single point-80% efficiency

• Water is naturally derived froms sources-40% efficiency
