Waves, Tides and Coasts Word Search

About this puzzle

This list is about the edge of the sea and the forces that shape it. Tides rise and fall; currents and swells carry energy across open water until it arrives as breakers and surf; and the shoreline answers with coves, cliffs, dunes, sandbars and inlets. JETTY names one of the structures people build to manage the coast. The list suits a geography lesson or a beach holiday equally well.

The default layout is Medium on a 13×13 grid. Easy, Medium and Hard each use their own checked layout of the same words, and every one can be printed in standard or large print on US Letter or A4.

Word notes

Tide

The regular rise and fall of the sea, caused mainly by the pull of the Moon; most coasts have two high tides a day.

Estuary

Where a river meets the sea and fresh water mixes with salt water.

Sandbar

A ridge of sand built up by waves and currents, often lying just below the surface.

Dune

A hill of sand piled up by the wind; dune grasses help hold coastal sand in place.

Swell

Long, rolling waves that have travelled far from the storm or wind that created them.

Undertow

Water flowing back out to sea beneath breaking waves.

Jetty

A structure built out into the water to protect a harbor or shoreline.

Try this after the puzzle

On a simple coastline sketch, ask solvers to label six of the words in the right places: cliff, cove, dune, sandbar, estuary and jetty. Then talk through one safety word — UNDERTOW or CURRENT — and why lifeguards put up warning flags. Older students can connect TIDE to the phases of the Moon.
