Answer:
A. True
Explanation:
Oceanic crust, while older than plateaus of rocks found far away from volcanic activity, it is much thinner, denser, younger, and of different chemical composition than continental crust. Continental crust is typically 30-50 km thick, whilst oceanic crust is only 5-10 km thick. On the other hand, plateaus of rocks are formed from volcanic activities and are of more recent occurrence than oceanic crust.
After viewing and researching the picture given above, the approximate age of the Redwall limestone in million years is from 318 to 359 million years.
Answer:
<u>submerging rift zone</u> due to slab pull
Explanation:
- It is a low lying area found on both land and seas of oceanic ridges subduction zones along the convergent plate boundaries which are sited for long-lived hot spots in volcanic ocean basins and transforms faults are a result of divergent boundaries.
- As the older and denser rocks sink deeper into the mantel and fall along the zone of hot spots. Grabens being an example of a rift valley on land is the center of mega-earthquake going deep down to the center of the mantel.
- Overplayed by the lighter and less dense material or the slabs made up of silicon layers. Impacted by slab push and pull. This process has its history with the isostatic movements of the earth as the earth keeps in balance the cycle of geomaterials.
<span>Deserts landscapes are jagged and rocky due to high erosion rates and chemical weathering. The chemcial weathering changes the physical character of the rocks which is the cause of it being jagged and rocky.
