Crumbling — Erosion by Water, Wind & Ice Flash Flood Narrows

Hi!

I'm Crumbling.

Welcome to Flash Flood Narrows!

Will you help me investigate erosion by water, wind & ice?

The Grumblies have mixed up our clues.

Let's check the evidence!

Water, wind and moving ice can transport sediment.

Erosion describes that movement, not simply the breaking of a rock.

Which agent can carry rock with ice?

  • A. A cloudless sky
  • B. A glacier
  • C. A stationary dry leaf

The answer is B: A glacier

Water, wind and moving ice can transport sediment.

Erosion describes that movement, not simply the breaking of a rock.

That clue helps us make sense of this place.

Faster moving water often carries more or larger particles than

slower water under comparable conditions.

Wind more easily moves loose small particles than large heavy stones.

What does the faster-water model show?

  • A. More sand carried in this test
  • B. All rivers carry exactly the same load
  • C. Water destroys the sand

The answer is A: More sand carried in this test

Our model carries more sand at the faster water setting.

Keep the channel and amount of sand the same to

compare the effect of water speed.

Hmm...

how does that connect to our first clue?

Our model carries more sand at the faster water setting.

Keep the channel and amount of sand the same to

compare the effect of water speed.

Which material is wind more likely to move?

  • A. A large embedded boulder
  • B. A mountain ridge
  • C. Loose fine sand

The answer is C: Loose fine sand

Faster moving water often carries more or larger particles than

slower water under comparable conditions.

Wind more easily moves loose small particles than large heavy stones.

Nice investigating!
