Question 1 · Multiple choice — select all that apply

Soils vary across space and time. Which explanations are supported in the text?

Soils can differ across continents due to climate and geology. Soils may change within a region depending on vegetation or land use. Soil properties are mainly determined by climate, so they change little within the same region. Differences in relief can influence soil characteristics. Soils reflect their surroundings and their history.

Question 2 · Multiple choice — select all that apply

The text describes soil profiles as “environmental stories.” What does this metaphor imply?

Soil profiles are mainly artistic representations of landscapes. Soil profiles contain visible clues about past and present environmental conditions. Soil profiles must be interpreted carefully to understand their meaning. Different observers may focus on different aspects of the same profile. Soil profiles show connections between land, water, air, organisms, and humans.

What are key characteristics and purposes of soil monoliths?

They preserve an undisturbed vertical slice of soil. They allow comparison of soils from different environments. They permanently stop soil formation at the original site. They help visualize soil structure beyond flat photographs. They capture a specific moment in a soil’s long development.

Question 4 · Multiple choice — select all that apply

Which statements correctly describe how soil-forming factors influence soil development?

Soil formation is shaped by the interaction of multiple factors rather than a single cause. Parent material alone determines how a soil will look and function. Climate influences processes such as weathering and biological activity. Time allows soil characteristics to develop gradually. Soil formation stops once distinct layers have formed.
