Transcript Chunky Weathering and Erosion

Chunky
Weathering and
Erosion
Earth’s surface breaks into chunks
and the chunks move.
The breakdown of rocks at or
near Earth’s surface is called?
weathering
What are the two types of
weathering?
Physical and chemical
Which type of weathering
actually changes a rock’s
composition?
chemical
What is it called when ice
expands in a crack in a rock?
Ice wedging or frost action
Abrasion is a form of which
type of weathering?
physical
When limestone bedrock
dissolves due to chemical
weathering it can form?
Sinkholes or caverns
An example of biological
weathering would be . . .
Plant root in rock
The weathering of bedrock
ultimately forms this important
material.
soil
The driving force of most
erosion is?
gravity
Which of the following are
considered mass movement?
soil creep
landslide
rock fall
They’re all mass movement
V-shaped valleys are carved by?
Rivers and streams
True or false – rivers produce
sharp edged sediments
False – they produce rounded
sediments
Draw the cross section from
x to y
At what letters will erosion take
place?
B&D
The area of land drained by a
stream is called a?
watershed
What type of erosion created
this formation?
wind
Glaciers carve what shape
valleys?
U
What arrangement of
sediments are left by glaciers?
Unsorted
What other evidence of
glaciation might be found in a
U-shaped valley?
Striations or erratics
This glacial formation is called
a?
drumlin
This long narrow island is
formed by?
Longshore current or wave
action
Which erosive force formed
these lakes?
Glaciers
Where on Earth is this process
the most dominant type of
erosion?
Beaches and deserts
Which erosive force moved this
boulder to its present location?
