What is the main difference between soil and dirt?
Soil is productive and essential for life.
Soil is only found in forests.
Soil is just dirt in a different location.
Which of the following is a component of soil? Select all that apply.
Water & air
Sand, silt, clay
Living stuff
Organic materials
What is the term used for the process of breaking down rocks into soil?
Deposition
Erosion
Weathering
What role do pioneer species play in soil formation?
They decompose and contribute organic material to the developing soil.
They thrive in mature soil only.
They are harmful to soil health.
What do living things like worms, plants, and fungi do to the soil?
They help mix and aerate the soil and return nutrients when they die.
They only take nutrients from the soil and never give anything back.
They take minerals out of the soil and make it worse over time.
Which environment would have the fastest decompostion and soil development?
Warm & wet
Cold & dry
Mild & humid
What is soil texture determined by?
The percentages of sand, silt, and clay
The color and depth of the soil
The type of plants growing in the soil
What use is loamy soil (mix of silt, sand, and clay) perfect for?
Construction
Manufacturing
Agriculture
Why is soil considered a fantastic filter?
It adds nutrients to water
It removes harmful substances from water
It increases water temperature
What can happen if farmers plant the same crop repeatedly without proper soil care?
Soil loses its fertility and can no longer support plants and animals.
Soil becomes more porous and lets water flow too quickly.
The soil stays healthy and full of nutrients forever.
What is a major problem caused by overgrazing?
Overgrazing removes grasses and compacts soil, causing erosion and loss of soil fertility.
Overgrazing improves soil porosity and water flow.
Too many cattle help mix the soil and increase its nutrients.
What happens when soil is disturbed during deforestation and tilling?
Water retention increases
Nutrients are added
Soil can be blown away
Why is soil important for helping reduce carbon dioxide in the atmosphere?
Soil increases erosion, which removes carbon from the environment.
Soil releases carbon dioxide into the air during photosynthesis.
Soil acts as a carbon sink by storing carbon from plants and animals underground.
What is sustainability?
Development that ignores environmental concerns
Development that meets present needs without compromising future generations
Development that harms future generations
What does "replacement rate" mean?
The speed at which resources can replenish
