Freezing Rain
Acid Rain
Chemical Rain
Falling Rain
What are 2 ways that topsoil can lose its value?
Erosion from Wind and/or Water
Loss of Fertility
Loss of Weathering
Fertility from Wind and/or Water
Loss of Erosion
Which type of weathering most likely has occurred to this sculpture?

Animal Actions from woodpeckers
Plant Actions from roots shifting and cracking it
Abrasion from sand in the wind
What are 3 good ways to conserve farmland topsoil?
Contour Chopping
Contour Plowing
Conservation Plowing
Conservation Rotation
Crop Rotation
If I place one of these marble statues in a hot wet tropical village, and another in a hot wet urban city. Which would likely weather more quickly?
Urban City Due to Acid Rain or Carbonic Acid in Fog/Rain
Tropical Village Due to Monkeys and Bananas
Earthworms decompose decaying organic matter from plants and animals,
therefore creating rich fertile _____________________
Silt
Sand
Clay
Humus
Which soil is most valuable because it has equal parts, is permeable, and rich in nutrients?
Sandy Soil
Loam Soil
Clay Soil
Bedrock
In the correct order, what would you find in the A Horizon, B Horizon, and then C Horizon?
Subsoil, Weathered Bedrock, Clay
Clay, Topsoil, Weathered Bedrock
Topsoil, Subsoil, Weather Bedrock
Subsoil, Sub Subsoil, Sub Sub Subsoil.

Frost Wedging
Abrasion
Plant Growth
Animal Actions
Which type of weathering caused the Grand Canyon?
Acid Rain from Pollution

Frost Wedging from Ice
Abrasion from Water
Why should farmers practice conservation plowing? What does it do for the soil?
Holds soil in place, adds nutrients, and retains moisture.
Loosens up soil, saves nutrients, blocks moisture.
Breaks up soil, depletes nutrients, causes moisture
Because it keeps King Kong away.
What is it called when you alternate crops to retain or restore nutrients in farmland soil?
Plow Rotation
Crop Plow
Crop Rotation
Crop Mix
Why is plant cover beneficial to preserving topsoil?
Roots hold soil in place, prevent water and wind erosion
Plants protect soil by breaking the force of falling rain.
Plants protect soil from blowing away by breaking force of wind.
Plant cover actually helps keep soil moist by blocking sunlight
What makes soil Loam?
It has equal parts of sand, silt, and clay
It is rich in clay
Has equal parts of bedrock, pebbles, and sand
Has equal parts of clay, rock, and gravel
Which horizon is not labeled or listed in this diagram?
A Horizon
B Horizon
C Horizon
D Horizon
What type of weathering is occurring due to the acids from the lichens growing on this rock?
Mechanical Weathering
Physical Weathering
Machine Weathering
Chemical Weathering
What type of chemical weathering is happening to these rocks in order to cause the iron to rust.
Rustification
Oxygenation
Oxidation
Acid Rain
What is the most obvious type of weathering occurring in the is picture?
Mechanical Weathering from Plant Growth
Chemical Weathering from Plant Roots
Mechanical Weathering from Animal Actions
Chemical Weathering from Carbonic Acid in Fog
Why is rich fertile soil so valuable?
Because it is dark and brown
Because it has poop in it
Because it is full of dead stuff
Because it is a limited natural resource
