Final Jeopardy
$100 Question from H1
the average weather conditions in
An area over a long period of
time
$100 Answer from H1
Climate (Temperature)
$200 Question from H1
The height (typically measured
in feet above sea level) to
which something is elevated or
to which it rises
$200 Answer from H1
Elevation
$300 Question from H1
The more _______ _____ of a
rock that is exposed to weathering,
the faster the rock will wear down.
$300 Answer from H1
Surface Area
$400 Question from H1
Rocks that are made of ______
minerals will weather faster than
rocks that are made of _______
minerals.
$400 Answer from H1
Softer, harder
$500 Question from H1
A process by which softer, lessweather resistant rock wear away
and leave harder, more weatherresistant rock is called…
$500 Answer from H1
Differential Weathering
$100 Question from H2
Rain, snow or sleet that contains a
high concentration of acids (an
agent of chemical weathering)
$100 Answer from H2
Acid Precipitation
$200 Question from H2
These are agents of chemical
weathering (name three)
$200 Answer from H2
Water, weak acids/plant
Acids, air
$300 Question from H2
What causes acid precipitation
$300 Answer from H2
The burning of fossil
fuels
$400 Question from H2
a chemical reaction in which an
element, such as iron, combines
with oxygen to form an oxide.
This form of chemical
weathering forms rust.
$400 Answer from H2
Oxidation
$500 Question from H2
Another name for living
things such as algae or
fungus (which live on rocks)
which produce acids that
slowly break down rock.
$500 Answer from H2
Lichens
$100 Question from H3
The grinding and wearing away
of rock surfaces through the
mechanical actions of other rocks
or sand particles
$100 Answer from H3
Abrasion
$200 Question from H3
These are agents of Mechanical
(Physical) Weathering (list at
least 4)
$200 Answer from H3
ice, wind, water, gravity,
plants and animals
$300 Question from H3
An agent of mechanical weathering
that causes rocks to fall (rock
slide/landslide) causing abrasion as
they hit each other
$300 Answer from H3
Gravity
$400 Question from H3
When water seeps into cracks during
warm weather, temperatures drop,
water freezes and expands pushing
against the sides of the crack
(pressure), widening the crack until
the rock breaks up/apart
$400 Answer from H3
Ice Wedging
$500 Question from H3
Describes how a rock changes
after it has been in a riverbed for
a long time
$500 Answer from H3
the edges of the rock are worn
away and its surface becomes
smoother
$100 Question from H4
The process by which wind, water,
ice or gravity transports soil and
sediment from one location to
another
$100 Answer from H4
Erosion
$200 Question from H4
The process in which
material/minerals are laid down
after being carried away
$200 Answer from H4
Deposition
$300 Question from H4
The process by which rock
materials are broken down by the
action of physical or chemical
processes
$300 Answer from H4
Weathering
$400 Question from H4
What agent of weathering can
weather rock mechanically and
chemically?
$400 Answer from H4
Water
$500 Question from H4
Name four factors that affect how
fast weathering happens
$500 Answer from H4
Temperature, moisture,
Elevation and slope
$100 Question from H5
The roots of plants can
Grow deep into cracks and cause
Mechanical weathering
$100 Answer from H5
True
$200 Question from H5
Elevation and slope can affect
How fast weathering occurs
$200 Answer from H5
True
$300 Question from H5
Rocks with very little surface
area weather faster than rocks
With a lot of surface area
$300 Answer from H5
False
$400 Question from H5
Temperature is a major factor
In both chemical and mechanical
weathering
$400 Answer from H5
True
$500 Question from H5
In chemical weathering, the
chemical composition of
A rock does NOT change.
$500 Answer from H5
False
Final Jeopardy
Briefly, how are caves/caverns
formed underground?
Final Jeopardy Answer
Acid precipitation seeps into ground
and dissolves Limestone
