weathering & soil

QuestionAnswer
the soil horizon that contains humus A HORIZON
a soil mixture of equal parts of sand, silt & clay LOAM
the type of weathering that changes the size & shape of the rock MECHANICAL (PHYSICAL)
a mixture of particles of weathered rock & organic matter SOIL
the process that results in the breaking down of rock WEATHERING
the basic material (ingredient) for soil formation BEDROCK (or PARENT ROCK) (or R HORIZON)
the agent(s) that can weather rock BOTH chemically & physically PLANTS & WATER
the two main features of climate TEMPERATURE & MOISTURE (HUMIDITY/PRECIPITATION)
the climate in which chemical weathering is the most rapid (fastest) HOT, WET CLIMATE
a ___ rock has many tiny, connected spaces (pores) PERMEABLE
these two agents of physical weathering are the primary causes of mechanical weathering due to their prevalence (prevalence means they are active all over the world) WATER & WIND
the breaking down of rock due to the scratching & grinding action of rock particles carried by water, wind & ice ABRASION
animals that move rock & soil underground (burrowing) are agents of ___ weathering MECHANICAL (PHYSICAL)
the property of soil that describes the ability of soil to support plant growth SOIL FERTILITY
without a layer of topsoil, this horizon cannot form B HORIZON (SUBSOIL)
does every soil profile contain every soil horizon? NO
the type of weathering that results in changes to the mineral composition of the rock CHEMICAL
water, warm daytime temperatures & freezing nighttime temperatures produce which agent of weathering? ICE WEDGING
the best protection against soil loss due to erosion is ___ VEGETATION
T/F: A ROCK THAT IS PERMEABLE WEATHERS FASTER THAN AN IMPERMEABLE ROCK TRUE
T/F: A ROCK AT THE BASE OF A MOUNTAIN WEATHERS SLOWER THAN A ROCK AT THE TOP OF A HIGH ELEVATION MOUNTAIN FALSE
T/F: A ROCK IN A COLD, DRY CLIMATE WEATHERS FASTER THAN A ROCK IN A COLD, WET CLIMATE FALSE
T/F: A SOFT ROCK WEATHERS FASTER THAN A HARD ROCK TRUE
T/F: A ROCK IN A WARM, WET CLIMATE WEATHERS FASTER THAN A ROCK IN A COLD, WET CLIMATE TRUE
MECHANICAL/CHEMICAL: OXYGEN IS AN AGENT OF ___ WEATHERING CHEMICAL
MECHANICAL/CHEMICAL: WIND IS AN AGENT OF ___ WEATHERING MECHANICAL
MECHANICAL/CHEMICAL: CARBON DIOXIDE IS AN AGENT OF ___ WEATHERING CHEMICAL
MECHANICAL/CHEMICAL: ACIDS IN PLANT ROOTS ARE AGENTS OF ___ WEATHERING CHEMICAL
MECHANICAL/CHEMICAL: FREEZING & THAWING IS AN AGENT OF ___ WEATHERING MECHANICAL
MECHANICAL/CHEMICAL: ICE WEDGING IS AN AGENT OF ___ WEATHERING MECHANICAL
MECHANICAL/CHEMICAL: BURNING FOSSIL FUELS PRODUCES AN AGENT OF ___ WEATHERING CHEMICAL
MECHANICAL/CHEMICAL: ABRASION IS AN AGENT OF ___ WEATHERING MECHANICAL
MECHANICAL/CHEMICAL: WHEN WATER DISSOLVES ROCK, ___ WEATHERING OCCURS CHEMICAL
MECHANICAL/CHEMICAL: WHEN THE IRON IN ROCK REACTS WITH WATER & OXYGEN, ___ WEATHERING OCCURS CHEMICAL
MECHANICAL/CHEMICAL: WHEN TREE ROOTS GROW INTO ROCK, ___ WEATHERING OCCURS MECHANICAL
COMPLETE THE ANALOGY: MUDSLIDE IS TO LANDSLIDE AS ___ IS TO FREEZING & THAWING ICE WEDGING
the dark brown, nutrient-rich component of soil produced by decayed organic matter HUMUS
the horizon composed only of partly weathered rock C HORIZON
the first step in soil formation WEATHERING ROCK
the last horizon to form B HORIZON
the soil horizon that supports plant life/growth A HORIZON
the horizon containing both inorganic & organic soil components A HORIZON
because they break down organic matter, fungi, bacteria, insects & worms are called ___ DECOMPOSERS
increasing the amount of humus in soil will increase this property of soil FERTILITY
the process in which natural forces move rock and sediment EROSION
the process that results in the formation of soil WEATHERING
the agent of chemical weathering produced by the burning of fossil fuels ACID RAIN
without ___, soil cannot form BEDROCK (or PARENT ROCK) (or the R HORIZON)
___ is the smallest-sized soil particle CLAY
the soil particle size that is smaller than gravel but larger than silt SAND
the soil particle size that is larger than clay but smaller than sand SILT
the process that results when the moving water, wind or glacier that is carrying sediment slows down DEPOSITION
ORGANIC or INORGANIC: humus ORGANIC
ORGANIC or INORGANIC: minerals INORGANIC
ORGANIC or INORGANIC: water INORGANIC
ORGANIC or INORGANIC: coal ORGANIC
ORGANIC or INORGANIC: rock ROCKS ARE MIXTURES - THEY CAN CONTAIN ORGANIC MATERIAL OR THEY CAN BE INORGANIC! (mostly, they're inorganic)
ORGANIC or INORGANIC: soil SOILS ARE MIXTURES - THEY CAN CONTAIN ORGANIC MATERIAL OR THEY CAN BE COMPLETELY INORGANIC!
property the describes the amount of different-sized particles a soil contains SOIL TEXTURE
in addition to weathered rock & humus, healthy soil contains ___ and ___ AIR & WATER
