Landling — Rivers, Valleys & Canyons Arch Canyon

Hi!

I'm Landling.

Welcome to Arch Canyon!

Will you help me investigate rivers, valleys & canyons?

The Grumblies have mixed up our clues.

Let's check the evidence!

Flowing water can erode rock and carry sediment, helping cut channels, valleys

and canyons.

These changes often build up over long periods.

What helps a river cut a channel?

  • A. Only growing crystals in still air
  • B. Water changing into magma
  • C. Erosion

The answer is C: Erosion

Flowing water can erode rock and carry sediment, helping cut channels, valleys

and canyons.

These changes often build up over long periods.

That clue helps us make sense of this place.

When water loses the ability to carry sediment, some material settles.

That deposition can build bars or other deposits along a river.

Where does the model's sandbar grow?

  • A. The fastest section removing sand
  • B. The slower depositing section
  • C. Only where all sand is removed

The answer is B: The slower depositing section

Our model's fast section carries sand away;

its slower section gains a sandbar.

Removing and depositing material can happen at different places along one river.

Hmm...

how does that connect to our first clue?

Our model's fast section carries sand away;

its slower section gains a sandbar.

Removing and depositing material can happen at different places along one river.

Can one river erode and deposit?

  • A. Yes, in different places or times
  • B. No, a river can do only one forever
  • C. Only in oceans

The answer is A: Yes, in different places or times

Our model's fast section carries sand away;

its slower section gains a sandbar.

Removing and depositing material can happen at different places along one river.

Nice investigating!
