UPDATED QUESTIONS AND
ANSWERS/GRADE A+ ASSURE
Karst def'n - CORRECT REPLY>>>> -Topography underlain by limestone,
dolomite, gypsum, or other rocks which can be affected by dissolution
4 conditions/things necessary for Karst to form - CORRECT REPLY>>>> -1. A
soluble rock at or near surface
2. A dense rock, highly jointed and thin-bedded
3. Entrenched valleys below uplands underlain by soluble and well-jointed rock
4. A region of moderate to abundant rainfall
Karst term: Terra rossa - CORRECT REPLY>>>> -Karst feature- A red clayey
soil (CL - CH) found on the ground and extending into joints and cracks, usually
on moderate to gentle slopes.
Karst term:Lapies - CORRECT REPLY>>>> -Grooved or fluted surface
resulting from the solution or limestone at or near the surface in an area of
high relief. Grooves range from a few millimeters to more than a meter,
commonly result in knifelike ridges.
,Karst term: Sinkholes - CORRECT REPLY>>>> -Circular depression, commonly
funnel-shaped. Two origins- doline, or a collapse of the rock over an
underground cavity.
Karst term: Sinkhole pond or karst lake - CORRECT REPLY>>>> -pond or lake
resulting from the clogging by clay of a doline sinkhole that perches water
above the water table
Karst term: Swallow holes - CORRECT REPLY>>>> -a hole in the bottom of a
sinkhole
Karst term: Karst window - CORRECT REPLY>>>> -a hole in the ground in
which one can observe an underground stream. A hole in a cavern which
breaks the surface.
Karst term: Uvala - CORRECT REPLY>>>> -an elongated karst window
Karst term: Polje - CORRECT REPLY>>>> -a sinkhole formed by solutional
modification of the rock in a previously faulted or folded structure.
Karst term: Solution-subsidence trough - CORRECT REPLY>>>> -A non-
tectonic feature, resulting from concurrent subsidence and solution along
joints or faults.
Karst term: Sinkhole or karst plain - CORRECT REPLY>>>> -A limestone plain
exhibiting sieve-like characteristics resulting from numerous sinkholes
,Karst term: Sinking creeks - CORRECT REPLY>>>> -Any surface creek or
stream which disappears underground in karst terrain (may disappear in a
swallow hole)
Karst term: Sink - CORRECT REPLY>>>> -the point at which a sinking creek
ends, often a swallow hole
Karst term: Blind valley - CORRECT REPLY>>>> -A valley that ends at a
swallow hole due to a prolonged period of upstream erosion above the
sinkhole. Solution or karst valley is a special type.
Karst term: Hum - CORRECT REPLY>>>> -isolated hill remnants due to
erosion
Karst term: Travertine - CORRECT REPLY>>>> -A deposit of calcium
carbonate precipitate that can be found in limestone caverns
Karst term: Dripstone - CORRECT REPLY>>>> -Travertine deposits resulting
from dripping from the ceiling of a cave or cavern- eg. stalactites and
stalagmites.
Karst term: Helictite - CORRECT REPLY>>>> -An irregular twiglike deposit
that forms in caverns when there's not enough water to form drips but the
surface remains damp or the water comes from a tiny hole or tube within the
deposit
, Two categories of glacial features - CORRECT REPLY>>>> -Continental
glaciation and Alpine glaciation
5 conditions required to classify a snow or ice field as a glacier: - CORRECT
REPLY>>>> -1. A large accumulation or mass of ice and snow
2. Must be located on land (or principally on land)
3. It must be formed by compaction and recrystallization of snow
4. There must be evidence of past or present movement
5. The glacier remains from year to year
Continental Glacier term:
Roche moutonnée - CORRECT REPLY>>>> -An elongated bedrock knob
oriented parallel to the direction of glacial flow and has a smooth rounded
upstream end and a steep rough downstream end. Erosional Feature.
Continental Glacier term:
Mammillated surface (Streamlined topography) - CORRECT REPLY>>>> -A
series of smooth rounded erosional rock mounts alternating with parallel
valleys resulting from the smoothing off of a mountainous region by the ice
cap. Erosional Feature.
*Three erosional features of Continental glaciation (Ice Caps) - CORRECT
REPLY>>>> -1. Ice scoured plain
2. Roche moutonnée
