Mission 1
By Tiffany West
Your
Task:
To investigate Earth’s
landforms and discover
how they are made! You
must proceed with caution!
All around you things will
be destroyed and built up!
Rocks change shape, size and/or form due to water or ice
movement, freeze and thaw, wind, plant growth, gases in the
air, pollution and catastrophic events such as earthquakes,
mass wasting, flooding and volcanic activity
•

Destructive
Processes =
Destroy
Constructive
Processes =
Build Up
Process 1:
Weathering
Weathering is a group of
processes that break down rocks
and sediment into smaller particles.
•
Some weathering processes take a
long time to occur, while some
weathering processes occur
quickly.
•
Weathering can be caused by
water, wind, ice, or plant roots.
•
•It
is a “destructive” process.
Watch how weathering and erosion work
together to wear away rock!

Process 2:
Erosion
Erosion is a process that
transports rock, soil or
sediment to a different
location.
•
•Water,
wind and ice
physically remove and
carry (erosion) rock, soil
and sediment and deposit
the material in a new
location.
•Erosion
process”
is a “destructive
Take a look at he link below to watch erosion in action!

Process 3:
Deposition
Deposition happens when
erosion deposits the
material in a new location.
•
•The
material builds up to
make new landforms.
Deposition is a
“constructive” process
•
Watch as the sediment is deposited.

Process 4
: Flooding
Flooding is when water rises and
overflows onto dry land.
•
•Water
saturates the ground and
washes away eroded rocks, soil and
sediment. The water expands to
cover more land and recedes back
to its normal banks.
•Flooding
is a “constructive” and
“destructive” process

•What
does flooding do to the
rocks, soil, and sediment?

•How
does flooding construct and
destruct the land around it?
Watch how scientists monitor streams
and rivers to determine when a flood
will occur.

Process 5:
Glacial Movement
The very slow movement of
glaciers
•
•Glaciers
are a large body of ice
moving slowly down a slope or
valley or spreading outward on a
land surface
•Glaciers
erode the land and
deposit the land in new places.
•Glaciers
are a “destructive” and
“constructive” processes.
•What
would the movement of
a glacier
do to a mountain?
•
LOOK at the pictures!
Watch the incredible glaciers as they move
massive amounts of rocks and sediment!

Process 6:
Earthquakes
A shaking or trembling of the
earth that is caused by volcanic or
tectonic activity
•
•As
plates in the earth move past
each other and cause friction, they
create a vibration that makes the
earth shake and move.
•Earthquakes
process
•What
are a “destructive”
causes an earthquake?

Read about earthquakes and learn
about their causes!

Process 7:
Volcanic
Activity
•
Molten or hot rock and steam
coming out of a vent in the crust of
the earth
•
A hill or mountain made up of
material that comes out of a whole
or crack in the earth
•
Something of explosively violent
potential
•
Volcanic activity is a “destructive”
and “constructive” process.
- Watch the videos and explain:
•
How is it destructive?
•
How is it constructive?
Watch the destructive and constructive force of volcanoes!
