Classify the hypotheses about fluids on Earth as falsifiable or non-falsifiable. Floating in the Great Salt Lake
in Utah is a lot of fun.

The Great Salt Lake is salty due
to a high rate of water evaporation
in the desert climate.

Magma erupting from the mantle
below Earth’s surface is hot and
fluid in nature.

Magma leaks up from the mantle
below Earth’s surface and spreads
out, forming a new ocean floor,
thereby causing land forms above
to move.
