The oceans are one of the most geologically active areas on the earth. Volcanoes, earthquakes and plate tectonics are part of this movement and activity Many volcanoes occur in the “ring of fire”, which is where the Pacific Ocean plate touches other plates.

Beachcombing Sea Glass

It’s fun to collect treasures from the beach. One of my favorites is collecting sea glass, sometimes called beach or ocean glass. Some define beach glass as clearer glass found in fresh water whereas,  ocean or sea class is from salt water and tends to be more frosted.

Beachcombing for sea glass can provide hours of educational fun.  Keeping a map of where you find your sea glass can give you clues about your treasures. Also, the glazing and roundness of the glass can give insight about the length of time the glass has been sanded and smoothed on the waves.

Sea or beach glass can be found in many waterways.  Fresh or salt water provide these glass treasures.
