which is bettter for wind erosion? gravel soil or sandy soil.
What do you mean by "better for wind erosion?"
Your question doesn't make sense.
Overgrazing does NOT limit soil erosion on farmland.
True
False
False.
Overgrazing causes bare soil patches, decreases vegetation cover, disturbs the soil structure, and compaction of soil. These activities enhance the chances of soil erosion due to wind and water. Therefore, overgrazing can lead to increased soil erosion on farmland.
To decrease soil erosion, humans can
a
plant more cover crops
b
plant less cover crops
a) Plant more cover crops.
Cover crops can help to reduce soil erosion, as their roots hold soil in place and reduce the impact of raindrops. They also provide additional vegetation cover, which can further help to stabilize the soil and prevent erosion. Therefore, planting more cover crops can be an effective way to decrease soil erosion.
To determine which soil type is better for wind erosion, we need to understand certain characteristics of gravel and sandy soil. Here's how you can analyze the properties of each soil type and determine their susceptibility to wind erosion:
1. Particle Size: Gravel soil consists of larger particles, whereas sandy soil comprises smaller particles. Since wind erosion depends on the ability of wind to pick up and transport soil particles, particle size plays a vital role. In this case, sandy soil has smaller particles that are more susceptible to being carried away by wind compared to gravel soil.
2. Soil Structure: The structure of the soil can also influence its resistance to wind erosion. Gravel soil typically has a coarser texture and larger gaps between particles, making it more challenging for wind to remove soil. On the other hand, sandy soil has a looser structure with smaller particles, which makes it less resistant to wind erosion.
3. Moisture Content: The moisture content in the soil affects its susceptibility to wind erosion. Gravel soil tends to retain water better due to its larger particle size and better drainage, making it less prone to drying out. In contrast, sandy soil drains water quickly and has lower moisture retention, leading to drier conditions that increase the risk of wind erosion.
Considering these factors, gravel soil is generally better for wind erosion control compared to sandy soil. However, it's essential to note that wind erosion is influenced by various other factors, such as vegetation cover, wind speed, and topography. Therefore, comprehensive soil and site assessments should be conducted to fully evaluate the potential for wind erosion in a particular area.
