I. Identification/ Enumeration
Write the term or scientists being defined or described by the following on your answer sheets.
Choose among the words below.
Plate Tectonics Slab Pull Ridge Push Convection current
Slab Pull Theory Tectonic Plate Movement Subduction process mantle-drag
1. A scientific theory that describes the large-scale motion of seven large plates and movements of a larger
number of smaller plates of the earth's lithosphere since tectonic processes began on earth between 3.3 –
3.5 billion years ago.
2-4. Three forces that drive the plate tectonics.
5. It flows within the mantle that causes plates to move due to difference in density.
6. It states that gravity and the plate are responsible for the plate tectonics through the subduction
process.
7. The _________________ is caused by the slab being dragged down into the mantle, dragging the
remainder of the plate with it.
8. It is considered as the major driving force of plate motion.
9. Beneath plates, convective flow in the mantle exerts a force, perhaps best described as
"____________."
10. This gravity-driven mechanism results from the elevated position of the mid-oceanic ridge, which
causes slabs of the lithosphere to "slide" down the ridge's flanks.
