BJU Space/Earth 5
BJU - Space and Earth Science - Chapter 5 (4th edition)
| Question | Answer |
|---|---|
| Creationary theory of the continent's origin that suggests that the earth's crust was a single super-continent which broke into tectonic plates during the Genesis Flood and rapid subduction of oceanic plates push them to their current positions | catastrophic plate tectonics |
| A naturalist theory that accounts for the shape and arrangement of the present-day continents by the slow movement of plates of crust floating on a semi-liquid layer of rock through many millions of years | continental drift theory |
| The theory that the crust of the earth consists of a relatively few semi-rigid plates floating on a plastic or semi-fluid mantle. It is the fundamental naturalistic theory that accounts for most geologic processes that have supposedly taken place. | plate tectonics theory |
| The observation that the oceanic tectonic plates are spreading away from the mid-ocean ridges and seem to be carrying the continents with them | sea-floor spreading |
| A process that is believed to occur as the relatively thin and denser oceanic lithosphere slides under a more massive but less dense continental crust and is bent downward hundreds of kilometers into the mantle | subduction |
| One of some 15 semi-rigid pieces of the earth's lithosphere that make up the outer shell of the earth. Most show some movement relative to adjacent plates. | tectonic plate |
| Molten rock deep within the earth. When magma escapes at the earth’s surface, it becomes lava. | magma |
| The forces, energy, and processes that formed and reshaped the earth’s continents, mountains, and ocean basins. | tectonics |
| A creationary model of the earth’s geologic history that classifies and arranges rocks in the sequence of their formation relative to the biblical Flood. Divides the earth’s history into the Creation Event, the time before the Flood, the Flood Event... | diluvial geologic column |
| Basic assumption that, in any undisturbed sequence of rock strata, the oldest or first-laid stratum is at the bottom of the sequence & the younger layers were placed in order above it | principle of superposition |
| A secular model of the earth’s geologic history that classifies and arranges rocks in the time periods of their supposed formation from 4.5 billion years ago to the present | geologic column |
| A rock layer in a sequence of strata. Marine sedimentary strata are assumed to be laid down nearly horizontally. Tectonic processes can tilt, fold, or fault strata. | stratum |
| Standard accepted secular model for the origin of all stars and planetary throughout the universe. Suggests that a star system forms slowly from a cloud of gas and dust | nebular hypothesis |
