Answer: D) None of the above

Explanation: The subschema differs from the schema in that one denotes the appearance of data in the Database Base Management System (DBMS) while the subschema which is also referred to as the external schema is that subset of the schema is visible or relevant to the user. Thus, It is the view of the database which is visible to an application program. Virtual tables in a database usually represents an object structures like a table which is the result of running certain database commands or functions such as the create table, view, select and so on. Virtual tables are not stored directly in database files.

Which observation about the Mid-Atlantic Ridge region provides the best evidence that the seafloor has been spreading for millio
SSSSS [86.1K]

Answer:

D. Seafloor bedrock is younger near the ridge and older farther away.

Explanation:

In a divergence boundary oceanic plates or continental plates move apart. The plates moves apart causing an uprising of molten magma to form a new crust. The divergent movement of plate is very prevalent in the oceanic plates.

The plates in the oceanic crust moves apart due to the up welling of aesthenosphere materials . These aesthenosphere materials(molten magma) are introduce to the ocean floor through the mid oceanic ridge . As this materials are introduced through cracks and fissures, the plates continue to drift apart. The molten magma later solidified to form a new crust closer to the oceanic ridge.  This is why sea floor bedrock closer to the ridge is younger as new rocks are formed here. But as one move farther away from the ridge the rocks become older. This phenomenon provide ample evidence that the seafloor is spreading. The older rocks found father away from the ridge proves the seafloor has been spreading given way for new rocks closer to the ridge.
