A geologist was exploring a deep cave in the desert, and discovered a fossilized school of fish. Which option below most likely explains why the geologist would find fish fossils in a desert cave?
Local wildlife went into the cave and had brought the fish to eat and then left, the fish scraps left behind in the cave became fossilized.
A few hundred years ago the lake that was there was used to irrigate the local farm lands and the lake was drained leaving the fish in the lake to be fossilized in the rock.
During the recent rainy season fish were able to swim in the flood waters to the cave, once trapped, they died and were fossilized in the rock.
Millions of years ago the desert was a lake that had fish, over time the Earth changed, the lake became a desert, and the fish in the lake were fossilized.
