5.15 - Capstone Questions for Lesson 5 and Soil Region Resources

Space explorers have discovered a new planet!

The Space Exploration Agency wishes to identify the soil types present at several possible landing locations on the newly discovered planet, Zeus.

Your mission as an Earth Scientist is to assess the soil properties present at the potential landing sites.

Activity: Predict the soil order present at several different locations on Planet Zeus. Make your predictions based on your knowledge of soil orders and the information presented on the map and in the table below.

 


Site Parent Material Climate/Moisture Regime Native Vegetation Topography
1 Silty Alluvium Hot and humid
Aquic
Rainforest Mountains and foothills
2 Sandy Alluvium Cool and wet
Xeric
Conifer forest Coastal plains and mountains
3 Loamy Glacial Till Warm and humid
Udic
Deciduous, hardwood forest Hilly river valleys and plains
4 Loess, windblown silt Warm and dry
Ustic
Prairie grassland High plains
5 Aeolian sand Continental
Hot Summer
Cold winter Ustic-Aridic
