I am doing that lesson right now, I will let you know the answers to the quick check as soon as I am done!
Wolf and I have the same answers, we are both right
Yep that true! 100%
tysmmm
they right
these answers still work today

1) The sustainable farming techniques are:
- rotating crops each year
- planting trees in between rows of crops
To determine the correct answers, we can evaluate each choice one by one:
- Tilling soil frequently: This is not a sustainable farming technique as frequent tilling disrupts the soil structure, leading to soil erosion and loss of nutrients.
- Limiting agriculture to rural areas: Although this might help preserve urban areas, it does not directly contribute to sustainable farming practices.
- Planting a single crop over a large area: This is not a sustainable farming technique as it leads to mono-cropping, which depletes soil nutrients and increases the risk of pests and diseases.
Therefore, the correct answers are rotating crops each year and planting trees in between rows of crops.
2) Hydroponics would be most useful for sustainable farming in a desert area with limited rainfall. In hydroponics, plants are grown without soil, with their roots submerged in a nutrient-rich water solution. This farming technique allows for controlled water usage, minimal wastage, and maximized crop yields regardless of the limited rainfall in a desert area.
To find the answer, we need to assess each situation:
- A temperate area with too much direct sunlight: In this case, shade and other means to protect crops from excessive sunlight would be more suitable than hydroponics.
- A mountainous area facing erosion: Hydroponics may not directly address erosion issues in mountainous areas. Other soil conservation techniques like terrace farming or contour plowing would be more appropriate.
- A tropical area facing deforestation: Hydroponics focuses on water use efficiency rather than addressing deforestation issues. Agroforestry or reforestation practices would be more relevant in this situation.
Therefore, the answer is a desert area with limited rainfall.
3) Terrace farming helps solve the issue of heavy rains washing away soil from mountainous farms. Terrace farming, also known as step farming, involves building a series of flat platforms on sloping land, which helps to reduce water runoff and soil erosion. By creating leveled terraces, the rainwater is slowed down and distributed evenly, allowing it to seep into the soil rather than washing away the topsoil on steep slopes.
Again, let's evaluate each option:
- Reduced biodiversity: Terrace farming may contribute to maintaining or increasing biodiversity since it creates multiple levels of vegetation and habitat niches.
- A crop requiring too much of one nutrient in the soil: Terrace farming does not directly address nutrient imbalances. Crop rotation, adding organic matter, or using fertilizers can help address nutrient requirements.
- Direct sunlight drying out a crop: While terrace farming makes better use of available water and reduces erosion, it does not specifically address the issue of direct sunlight drying out crops. Shade structures or adjusting planting techniques should be employed to address this particular problem.
Therefore, the answer is heavy rains washing away soil from mountainous farms.
