The following is true about Earth's history EXCEPT
Over the past three decades, earth scientists have made great strides in understanding the Earth’s workings. Scientists also used the concept of uniformitarianism to link what we know about current processes to past events; the present is the key to the past.
Earth’s history is recorded in the rocks of the crust. Earthquakes rip along plate boundaries; volcanoes spew fountains of molten lava; mountain ranges and seabed are constantly created and destroyed.
Earth scientists have long been concerned with deciphering the history and predicting the future of this active planet
Uniformitarianism states that the natural laws we know today have been constant over the geologic past.
