1. Examine this chart and answer the following question.     What is the LARGEST component of Organic Matter in the breakdown of soil?

Explanation

Humus is the correct answer because it is the largest component of organic matter in the breakdown of soil. Humus is the dark, organic material that forms in soil when plant and animal matter decompose. It is rich in nutrients and helps to improve soil structure and fertility. Roots and organisms also contribute to the breakdown of organic matter, but humus is the largest component.

2. The layers of soild are grouped together into _______________.

Explanation

The layers of soil are grouped together into horizons. This refers to the different layers of soil that are formed over time due to various processes such as weathering, erosion, and deposition. Each horizon has distinct characteristics, such as color, texture, and composition, which are influenced by factors like climate, vegetation, and parent material. These horizons play an important role in determining the fertility and overall health of the soil, as well as its suitability for different types of plants and crops.

Submit
3. The fate of soil erosion depends on ________________ .

Explanation

The fate of soil erosion depends on multiple factors, including climate, slope steepness, and the type of vegetation. Climate plays a significant role as it determines the amount and intensity of rainfall, which can lead to erosion. Slope steepness affects the speed at which water flows over the surface, increasing the likelihood of erosion. The type of vegetation also plays a crucial role as plants help stabilize the soil by reducing the impact of rainfall and holding the soil together with their roots. Therefore, all of these factors contribute to the fate of soil erosion.

Submit
4. This soil component is made from dead animal and plant matter.  it helps to enrich the soil.

Explanation

Humus is the correct answer because it is a soil component that is formed from the decomposition of dead animal and plant matter. It is rich in organic matter and nutrients, which helps to enrich the soil. Humus improves soil structure, water holding capacity, and nutrient availability, making it essential for healthy plant growth.

Submit
5. Which of the following is NOT a major component of soil?

Explanation

Earthworms are not a major component of soil. They are organisms that live in the soil and help with the decomposition of organic matter, but they themselves are not considered a major component of soil. The major components of soil include mineral matter, which provides the physical structure, and humus, which is the organic component derived from decomposed plant and animal material.

Submit
6. The topsoil is the lighter layer below the darker layer.

Explanation

The given statement is false. The topsoil is actually the darker layer that is found on the surface of the soil. It is rich in organic matter and nutrients, making it ideal for plant growth. The lighter layer below the topsoil is called the subsoil, which is typically less fertile and contains less organic matter. Therefore, the correct answer is false.

Submit
7. The main source of organic matter in soil is _________________ .

Explanation

Plants are the main source of organic matter in soil. They contribute to the soil's organic content through the deposition of dead leaves, branches, and other plant materials. These organic materials are then broken down by soil microorganisms, such as bacteria and fungi, to release nutrients and create a nutrient-rich soil environment. Therefore, plants play a crucial role in the formation and maintenance of soil organic matter.

Submit
8. Compared to the past, rates of soil erosion are ___________.

Explanation

Rates of soil erosion are faster compared to the past. This implies that the process of soil erosion is occurring at a quicker pace now than it did in previous times.

Submit
9. Human activities, such as farming, logging, and construction, have Slowed down the amount of erosion that occurs today.

Explanation

The statement claims that human activities have slowed down the amount of erosion that occurs today. However, this statement is false. Human activities such as farming, logging, and construction actually contribute to increased erosion. Farming practices like plowing and deforestation for logging lead to the removal of vegetation, which reduces the ability of the soil to hold onto water and increases the likelihood of erosion. Construction activities can also disrupt natural drainage patterns and increase erosion. Therefore, human activities have not slowed down erosion but rather have accelerated it.

Submit
10. In which of the following areas will soil formation be GREATEST?

Explanation

Soil formation is influenced by several factors, including climate, topography, and time. In a warm, wet climate, there is abundant rainfall and higher temperatures, which accelerate the weathering of rocks and the decomposition of organic matter. This promotes the breakdown of minerals and the accumulation of organic materials, leading to the formation of fertile soil. A flat area provides a larger surface area for the accumulation of sediment and organic matter, allowing for greater soil formation compared to a steep slope. Therefore, in a flat area in a warm, wet climate, soil formation will be the greatest.

Submit
11. Farmers can prevent soil erosion by strip cropping on hills.

Explanation

Strip cropping is a method used by farmers to prevent soil erosion on hills. It involves planting different crops in alternating strips across a slope. This helps to break up the flow of water and slow down its movement, reducing the risk of soil erosion. The different crops also have different root systems, which further helps to stabilize the soil. By implementing strip cropping, farmers can effectively prevent soil erosion and protect their land for sustainable agriculture.

Submit
12. A soil's texture is determined by ___________ ______________.

Explanation

A soil's texture is determined by the particle size. Different soil particles, such as sand, silt, and clay, have varying sizes and properties. The combination and proportion of these particles determine the texture of the soil. Sand particles are larger and feel gritty, while clay particles are smaller and feel sticky. Silt particles are intermediate in size. The texture of the soil affects its ability to retain water, drain properly, and provide nutrients to plants.

Submit
13. The  TOPSOIL is darker because of :

Explanation

humus or organic matter consists of decaying plant matter and decaying animal matter. topsoil also absorbs nutrients such as nitrogen from the atmosphere. the topsoil is soft and loose because of the animals such as moles, earthworms and groundhogs making tunnels and burrows.

Submit
14. Choose the correct answer(s) that BEST describe how humus can be increased in the soil.

Explanation

The correct answer options describe different methods to increase humus in the soil. Planting cover crops after harvesting corn or wheat helps to add organic matter to the soil, which eventually contributes to the formation of humus. Adding cow, horse, or chicken manure and turning it under in the spring also enriches the soil with organic material, promoting humus formation. Composting food scraps, egg shells, leaves, and coffee grounds and incorporating them into the soil before plowing also adds organic matter, which enhances humus content in the soil.
