Earth’s Surface JEOPARDY REVIEW
Vocab
Soil
Weathering
Random Stuff
Erosion
100 – What is a
floodplain? Deposition
on a river bank (sides
of a river) after the river
floods
100- What’s the
difference between a soil
profile and a soil horizon?
Profile is the side view
of the layers and the
horizon is a layer
200 – What is humus?
What causes humus to
form? Humus is organic
material in soil; formed
from decayed remains
of plants/animals
300 – What factors affect
soil formation?
Temperature, climate –
how much rain, slope of
land, how much life is
in the area
100 – Give an example of
chemical weathering. Acid
precipitation – rain has a
high level of acid &
wears away rock faster;
oxidation- rust forming
200 – Imagine that over a
long time, wind blows.
After many years, the
rock’s shape changes.
What is this an example
of? abrasion
300 – Explain difference
between chemical and
physical weathering.
Physical – looks diff. but
is the same substance.
Chemical - looks
different because it is a
new substance.
400 – Give examples of
how plants and animals
cause weathering. Plant
roots break apart rocks
as they grow; animals
burrow and dig
500 – State if each is
weathering, erosion, or
deposition: 1) rain washing
away soil 2) waves
dropping sand on the
beach 3) glaciers scraping
rocks across earth’s
surface. 1-erosion, 2deposition, 3- weathering
100 – What are the
layers of the earth,
starting in the center
and working out? Core,
mantle, crust
100 – What is loess?
Very fine, baby powderlike sediment easily
eroded (blown) by wind
200 – What do
weathering and erosion
have in common?
Breaking down rocks
and minerals
200 – What force causes
mass movement, like a
landslide? gravity
200 – What is oxidation?
chemical weathering
caused by a substance
mixing with oxygen –
like rust forming
300 – What is included in
the Earth system? Living
things, nonliving
things, and all 5
spheres
400 – Does water cause
physical or chemical
weathering? Give
examples. Both –
abrasion and acid rain
400 – What is leaching?
When it rains, water
seeps down through
the soil layers & can
carry things from top
layers into lower layers
500 – Name all 5 spheres 500 – What would
and what they are.
happen if leaching never
Biosphere (living
happened? Humus from
things); atmosphere
top layers wouldn’t be
(layer above crust-air);
carried down into the
cryosphere (frozen
lower layers
water); hydrosphere
(water); geosphere
(layers of the earth)
300 – What is
vegetation? How can it
affect erosion? It is
plants. The roots help
hold the soil in place
and can slow the
wind.
300 – What’s the
difference between an
alluvial fan and a delta?
Alluvial fans formed
from deposition on land
while deltas are from
deposition in water, like
at mouth of a river.
400 – How does a
400 – How does a cave
sinkhole form? Roof of form? Groundwater can
a cave collapses
weather away
underground rock. You
are then left with an
empty space.
500 – How could a

cause erosion as it
go downhill; mudflowcarries sediment.
heavy rains cause mud
to flow downhill
