a crop planted primarily to manage soil erosion by wind and rain. The plant roots help anchor the soil
2. No till farming
No-till is a way of growing crops from year to year without disturbing the soil through tillage/plowing. Leaving crop residue (leftover stalks/leaves) in the ground helps protect soil from Wind and water erosion
3. Crop rotation
changing the kind of plant grown each season increases the fertility of the soil (better for growing crops). This doesn’t necessarily reduce erosion but saves nutrients in the soil.
Growing the same crop in the same place for many years in a row depletes the soil of certain nutrients. With crop rotation, a crop that leaches the soil of one kind of nutrient is followed during the next growing season by a different crop that returns that nutrient to the soil or draws a different ratio of nutrients
4. Contour farming
growing crops across or perpendicular to a slope rather than up and down the slope. Rows of crops slow water down, reduces erosion by water.
A contour map of kennesaw mountain shows the shape and slope of the mountain. Each line is called a contour line. The closer together the lines are the steeper the slope. Areas with lines far apart show flat land ( fields/creek bottoms)
a sloping piece of land that has had flat areas like steps built on it, for example so that people can grow crops there, slows water down as it runs off downhill.
A windbreak is the planting,usually made up of one or more rows of trees or shrubs, that provide shelter from the wind and protects the soil from erosion by wind.
The faster the water moves, the more EROSIVE ENERGY it has. Water is like the superman of the agents of erosion. The steeper the slope, the faster the water moves and eventually the whole mountain side can give way. You might not know one of the largest landslides in history occurred right here in the USA, When the volcanic Mount St. Helens, triggered by an earthquake, erupted on May 18,1980. Over 1300 feet of mountain was eroded in a very short time. Within 3 minutes, the lateral blast, traveling at more than 300 miles per hour, blew down and scorched 230 square miles of forest.
You have reached the almighty milestone for the year, the EOG, aka Milestone test.
as you take these tests you might be asked to show your thinking or work. Don’t be like this kid
When writing make sure you are answering the question. Go back and read the question maybe several times. ON the written parts, they are looking to see if your answer has everything the question asks, maybe more than one part. Write in complete sentences but don’t try to get too fancy. Stay on topic, you can say a lot with a few words, you don’t have to write an essay. Pace yourself, don’t spend too much time on a multiple choice question, mark it and come back if you need. Most of all : RELAX, you are all smart ladies and gentlemen and you will do fine if you take your time. GOOD LUCK
