Crumbling — Gravity & Rapid Landscape Change Landslide Ledge

Hi!

I'm Crumbling.

Welcome to Landslide Ledge!

Will you help me investigate gravity & rapid landscape change?

The Grumblies have mixed up our clues.

Let's check the evidence!

Gravity pulls material downhill.

Landslides can move rock and soil rapidly,

while other downhill movements are slow.

What pulls material downhill?

  • A. A compass pointing north
  • B. Mineral color
  • C. Gravity

The answer is C: Gravity

Gravity pulls material downhill.

Landslides can move rock and soil rapidly,

while other downhill movements are slow.

That clue helps us make sense of this place.

Steeper slopes, water and loss of vegetation can affect how material moves.

No single classroom model predicts every real hillside.

Can landscape change happen rapidly?

  • A. Only when rock turns into lava
  • B. Yes, a landslide can be rapid
  • C. No, all movement takes millions of years

The answer is B: Yes, a landslide can be rapid

Gravity pulls material downhill.

Landslides can move rock and soil rapidly,

while other downhill movements are slow.

Hmm...

how does that connect to our first clue?

Our supplied slope tests lose more loose soil from the

bare steep tray than the planted gentler tray.

These are model results to compare,

not a reason to visit an unstable slope.

Which tray lost more soil in our record?

  • A. The bare steep tray
  • B. The planted gentler tray
  • C. Both lost no soil

The answer is A: The bare steep tray

Our supplied slope tests lose more loose soil from the

bare steep tray than the planted gentler tray.

These are model results to compare,

not a reason to visit an unstable slope.

Nice investigating!
