Earth Systems in APES (4.1, 4.2, 4.3)

What are properties of the soil determined by

• time

• parent material

• climate

• topography

• ALL of these determine the properties of the soil

The climate affects the type of soil that is created. Which of the following biomes would result in rapid weathering, leaching of nutrients, decomposition of organic detritus due to a lot of rain and warm temperatures.

• Tundra

• Coniferous Forest (Boreal Forest)

• Deciduous Forest

• Tropical Rain Forest

How does compacting soil from anthropogenic means impede water drainage?

• Drying at deeper layers of soil

• Waterlogging-water not draining

• preventing soil development

• Each of these is an affect of compacted soil

Which of the following has the greatest permeability?

• gravel

• sand

• clay

• silt

Which of the following types of soils organic material have high CECs (Cation Exchange Capacity)?

• gravel

• sand

• clay

• silt

What is the best type of soil for agriculture?

• silt

• loam

• sand

• clay

Why might very old soil be nutrient poor in the picture above?

• more organic material is present

• plants and water leaching nutrients

• less biodiversity

• soil is compacted

What horizon is decomposed organic material and is most pronounced in forests

• O horizon

• A horizon

• E horizon

• D horizon

Which horizon is considered the topsoil, is the organic mixed with mineral material, and has the most biological activity?

• O Horizon

• A horizon

• E horizon

• B horizon

This soil layer is found in some acidic soils and it is where metals such as iron, aluminum, and other nutrients are leached from above.
