Explanation / Answer

18) Answer: the oceanic plate subducts in oceanic-continental plate boundaries.

Explanation: This is because the rocks that form the oceanic crust are denser and thinner than the rocks that form the continental crust. The process by which the oceanic crust is pulled under the continental crust is called subduction and the zone at which this occurs at the plate boundaries is called the subduction zone.

19) Answer: Elastic materials

Explanation: elastic materials deforms under the applied pressure or load upto the elastic limit and returns to their original or initial position or state upon release of pressure or load. But plastic materials will not come back to their original state upon relesase of pressure.

20) Answer: in eroded anticline, rocks increase in age toward center of the structure.

Explanation: An anticline is a fold shaped like an arch the oldest rocks in the center of the fold. Usually the rock layers dip away from the contre of the fold.

The counterpart of an anticline is a syncline, a fold shaped like a trough with the youngest rocks in the center of the fold. The layered rock usually dips toward the synclines hinge line.

In places where folded rock has been eroded to a plane, an anticline can usually be distinguished from a syncline by whether the beds dip toward the center(syncline) or away from the center(anticline). Also the older rocks are found in the center of an eroded anticline, whereas the youngest rocks are found in the center or core of syncline.

21) Answer: the youngest rocks found on the seafloor at mid-ocean ridges.

Explanation: The youngest rocks on the ocean floor are found near underwater mountain chains known as mid-ocean ridges. These ridges are formed as continental plates move apart and mantle material moves in to fill the space

22) Answer: Hawaii is located on a convergent boundary

Explanation: Two plates move towards one another and one is dragged down (or "subducted") beneath the other. Convergent plate boundaries are also called "subduction zones" and are typified by the Aleutian Trench, where the Pacific Plate is being subducted under the North America Plate. in this process Howaii island was formed.
