The primary force responsible for transporting rock material on Earth’s surface is _____________________
GRAVITY

11. EROSION Agents of Erosion: Page 9 Distinctive Marks left behind
Running Water- (major agent)
Causes V- shaped valleys
2. Wind – (mainly in arid areas)
Deflation and sandblasting
Mushroom RockS
3. Glaciers – (mainly in polar & mountainous areas)
Deposits unsorted sediments
and U-shaped valleys
4. Gravity- (major FORCE)
Deposits unsorted sediments
Angular sediments

WIND AS AN AGENT OF EROSION
Wind can move (erode!) sediments only if they are small, and dry.
Wind usually blows the clay and silt completely away, and then blows sand around for thousands of years.
Because it can’t lift the sand up very high, the bottoms of rocks are eroded more than the tops.
Desert landscapes often have these “mushroom rocks”.

Turns V-shaped valleys into U-shaped valleys

16. GLACIAL STRIATIONS Page 9
These parallel scratches in the bedrock were caused by a glacier dragging rocks across it.
The scratches or striations they tell us what direction the glacier moved in.
Scratched and grooved bedrock, unsorted and scratched deposits are characteristic of glaciers
