Aqualing — Waves, Tides & Currents Shipwreck Canyon

Hi!

I'm Aqualing.

Welcome to Shipwreck Canyon!

Will you help me investigate waves, tides & currents?

The Grumblies have mixed up our clues.

Let's check the evidence!

Wind commonly makes surface waves.

Waves carry energy;

water near the surface often moves back and forth

rather than traveling the whole ocean with one wave.

Which observation is a tide clue?

  • A. A marker simply moving east
  • B. A drawing of a fish
  • C. Repeated sea-level rise and fall

The answer is C: Repeated sea-level rise and fall

Our record has sea level rising and falling through the day,

while a floating marker moves east with a current.

Those are different observations.

That clue helps us make sense of this place.

Tides are repeating rises and falls in sea level influenced

mainly by the Moon and also the Sun.

Currents are directed flows of water.

What commonly generates surface waves?

  • A. Only dissolved salt
  • B. Wind
  • C. Only fish swimming

The answer is B: Wind

Wind commonly makes surface waves.

Waves carry energy;

water near the surface often moves back and forth

rather than traveling the whole ocean with one wave.

Hmm...

how does that connect to our first clue?

Our record has sea level rising and falling through the day,

while a floating marker moves east with a current.

Those are different observations.

Which process carries the marker east?

  • A. A current
  • B. A map's north arrow
  • C. An earthquake every hour

The answer is A: A current

Our record has sea level rising and falling through the day,

while a floating marker moves east with a current.

Those are different observations.

Nice investigating!
