Weathering
The process of breaking down rocks into smaller pieces
What is Weathering?
The process that moves bits of rock or soil from one place to another.
What is Erosion?
This is a model that describes the formation, breakdown, and re-formation of a rock.
What is the The Rock Cycle?
This is a mixture of weathered rock, water, air, bacteria, and decayed plant and animal material (humus).
What is soil?
This sphere is affected by volcanic eruptions by affecting landforms.
What is the Geosphere/Lithosphere?
The breaking of rock through chemical reactions
What is Chemical Weathering?
These are the four agents of erosion.
Wind, Water, Ice/Glaciers, Gravity
This rock is formed through compaction and cementation.
What is a Sedimentary Rock?
These are the layers of soil in order.
Horizon O (organic material/humus), Horizon A (topsoil), Horizon B (subsoil), Horizon C (partly weathered rock), Horizon R (bedrock/solid rock)
This sphere is affected by volcanic eruptions by affecting bodies of water.
What is the Hydrosphere?
This is the process that creates potholes in sidewalks/roads.
What is Ice Wedging?
What is Deposition?
This rock is formed through immense heat and pressure.
What is a Metamorphic Rock?
This is how soil texture is determined. Percentages of sand, silt, and clay must equal to 100%.
What is the soil triangle?
This sphere is affected by volcanic eruptions by affecting plant and animal life.
What is the Biosphere?
These are the three types of Chemical Weathering.
What is Oxidation, Hydrolysis and Carbonation?
This is the primary agent of erosion.
What is Running Water?
This rock is formed through the cooling and hardening of lava or magma.
What is an Igneous Rock?
This is the soil texture with the given percentages: 35% clay, 30% silt, 35% sand.
(pull up a picture of the soil triangle)
What is Clay Loam?
This sphere is affected by volcanic eruptions by affecting the climate.
What is the Atmosphere?
The five ways physical weathering breaks down rocks.
What is Ice, Plant Roots, Burrowing, Temperature, Gravity?
This is an example from our notes of landforms created by deposition.
What are Deltas? OR
What are Flood plains? OR
What are Sandbars? OR
What are Sand Dunes?
This process is how rocks turn into sediments.
What is weathering and erosion?
This type of soil has the lowest permeability.
What is Clay?
This is one of the important gases and compounds.
What is:
CO2 (carbon dioxide)?
SO2 (sulfur dioxide)?
H2O (water vapor)?
HNO3 or H2SO4 (nitric acid or sulfuric acid)?
CO (carbon monoxide)?
