Answer:
Option (C)
Explanation:
Sea-floor spreading refers to the splitting of the ocean floor thereby leading to the expansion of the seas and oceans. This process adds new materials to the ocean floor along the mid-oceanic ridge. This idea of sea floor spreading allowed the scientists to demarcate that the rocks that are present along the mid oceanic ridge are the younger and the rocks that are present away from the rocks are the older rocks.
Along the mid-oceanic ridge, the rocks are comprised of magnetic strips that shifts their orientation every time it erupts. This separation of sea floor takes place due to the plate tectonic movement. It generates earthquakes of various intensities in the subduction zone. The rocks of the oceanic crust are basaltic in nature and are very dense compared to the continental crust.
Thus, the correct answer is option (C).

The statements about the Rocky Mountains are true
The Rocky Mountains are known for their tall peaks that are surrounded by valleys, glaciers, and dense forests. More than just hills and mountains can be found there. Wide-open grasslands and running rivers are surrounded by hilly slopes.
The Appalachians are considerably older than the Rocky Mountains. The Appalachian Mountains were formed over the last 480 million years whereas the Rocky mountains began forming 60 million years ago.
The Cordillarians' eastern edge mountain range is the Rocky Mountains. National parks of great significance can be found in the mountain range.
