Answer:
Option (C)
Explanation:
The sea floor refers to the oceanic crust that are comprised of basaltic rocks. The basaltic rocks contains olivine, feldspar and some pyroxenes that are usually denser than the minerals that are found in the continental crust.
On the other hand, continental crust refers to the rocks that are found in the continental landmasses, often comprised of rocks that are granitic in nature. The minerals such as silicates, feldspars are less dense.
When continental plate are subducted under the oceanic crust, the rocks at greater depths undergoes partial melting as a result of which the rocks melts and forms magma. These magma becomes less dense due to the high temperature and rises up towards the the surface in the over-riding plate.
Thus, as the plate subducts, the rock chemistry changes , thereby making it less dense.
Hence, the correct answer is option (C).
The types of erosion is matched with their effects.
Explanation:
- wind -On a calm, sunny day, a weathered boulder rolls down from a steep cliff and falls into the sea.
- glaciers - Frozen water displaces a rock from its current location.
- gravity -A desert grows larger as sand particles are transported to farther regions.
- waves - Weathered particles from oceanic rocks and reefs are deposited on low-lying land by water.
