1. Which of these is made up of smallest particles of rocks which contain decayed matter of plants and animals?

• A. Land
• ✒️B. Soil
• C. Mineral

So all soil is composed of small pieces of the local rock and decayed vegetable or animal matter. The rock particles are classified on the basis of their size: CLAY is the smallest particles of broken rock in soil, less than . 0002mm in diameter, so it is a fine dust.

2. Which type is characterized for having particles that are packed tightly together?

• A. Loam
• ✒️B. Clay
• C. Sand

Solid. In a solid,the particles (ions, atoms or molecules) are closely packed together.

Clay soil–whether you call it adobe, gumbo, or just plain “heavy” soil–is composed of many flattened, tiny particles packed tightly together to form a dense mass with microscopic pore spaces.

3. What type of soil do you usually see in coastal community?

• A. Sand
• B. Clay
• ✒️C. Loam

Beach and offshore deposits have sand throughout the soil profile, while back barrier deposits tend to have clay or clay loams. Fluvial terrace deposits have sandy clay loam sub-soils while some estuarine valleys have entirely organic soil profiles.

4. How does each soil type differ?

• A. Texture
• B. Color
• ✒️C. A and B

Soils are named and classified on the basis of physical and chemical properties in their horizons (layers). "Soil Taxonomy" uses color, texture, structure, and other properties of the surface two meters to key the soil into a classification system to help people use soil information.

5. How does soil help plants?

• ✒️A. Soil provides anchorage
• B. It provides necessary nutrients for growth.
• C. Serves as home for many plants.
• D. All of the above.

Soil helps anchor plants and provides them essential elements of water and nutrients. Plants prevent soil erosion and provide organic matter.

6. This type of soil cannot hold water well. What type of soil is it?

• ✒️A. Sand
• B. Clay
• C. Loam

Sand: Sandy soils drain very fast and do not hold water very well. They have the largest particle size and feels gritty to touch. Sand particles do not bind very well and easily warms up in the Spring because they have more pore spaces that fill with air.

7. Which type of soil is good for making pots?

• ✒️A. Clay
• B. Loam
• C. Sand

Clayey soil is used to make pots, toys and statues.

8. This type of soil has loose particles.

• A. Clay
• B. Loam
• ✒️C. Sand

Sandy soils contain large particles which are visible to the unaided eye, and are usually light in color. Sand feels coarse when wet or dry, and will not form a ball when squeezed in your fist. Sandy soils stay loose and allow moisture to penetrate easily, but do not retain it for long term us.

9. Why is soil important to living things?

• ✒️A. Soil provides the necessary nutrients needed by plants.
• B. It serves as a place where people live.
• C. It forms part where we live.
• D. All of the above.

Soil provides ecosystem services critical for life: soil acts as a water filter and a growing medium; provides habitat for billions of organisms, contributing to biodiversity; and supplies most of the antibiotics used to fight diseases.

10. Which type of soil is best for planting?

• ✒️A. Loam
• B. Sand
• C. Clay

Best Soil For Plants:

The ideal blend of soil for plant growth is called loam. Often referred to as topsoil or black dirt by landscape companies, loam is a mixture of sand, clay, and silt. The estimated mixture is 40% sand – 40% silt – 20% clay.
