• Silt soil would create smooth surfaces for the sand sculpture.

A farmer wants to grow a variety of crops. Which soil should they choose?

• Sand soil would drain quickly and warm up fast in spring.

• Clay soil would hold nutrients for too long in crop growth.

• Silt soil would provide good drainage and nutrient retention.

Which of the following describe silt?

• It is smooth, has lots of mineral particles, and is easy to cultivate.

• It is fine, clumps together, and holds water from easily draining.

• It is good for farming and it is a combination of all the types of soil.

• It has gritty particles that can be seen and cannot hold a lot of water.

Which soil would be LEAST effective for a plant that needs a lot of water?

• Sand soil would drain too quickly, leaving the plant dry.

• Silt soil would compact easily, preventing proper drainage.

• Clay soil would become waterlogged, suffocating the plant.

• Loam soil would retain too much water, drowning the roots.

If you were creating pottery, which soil would be most appropriate?

• Silt soil would create a smooth finish on the pottery surface.

• Clay soil would be easily moldable and harden when fired.

• Sand soil would add texture and prevent the pot from cracking.

• Loam soil would provide a mix of textures for unique designs.

If you will become a farmer, which mineral is best to use as your fertilizer?

• Limestone should be mixed to the soil in your farm.

• Fluoride should be mixed to the soil in your farm.

• Phosphate should be mixed to the soil in your farm.
