Answer:
Sea floor spreading theory is given Harry Hess the line of evidence that support this are given as under.
Explanation:
Evidence from Molten Matter
In the 1960s scientists found that there is a presence of new materials from below that need the lava to be uplifted and spread along the boundaries of mid-oceanic ridges i.e the lava or magma spreads through the active plate margins of both plates. The red sea is newly formed is an example of spreading, <u>(a process of oceanic basin creation)</u>.
Evidence from Magnetic strips
The magnetism of the earth helped the scientists study the process of seafloor spreading as the newly formed lava gets deposited on either side of the ridges it takes the magnetic properties of the earth. The ocean floor is divided into strips of north and south after cooling.
Active and passive plate margins.
The tri-junction of plates and newly discovered plate like that od red sea and splitting of the rift valley and transform faults. Movement of continents away from each other. Examples include Eastern pacific rise and Mid Atlantic ridge.

Information about the distribution of mineral deposits would likely be found on an economic activity map.
Answer: Option A
<u>Explanation:</u>
Economic activity map is the map which deals with the activities which are economic in nature. Since the major idea of the subject of Economics is to distribute the resources which are scarce in nature and needed to be distributed for the purposes which need resources.
This map will talk abut the distribution of the deposits of the minerals to the activities which would require minerals for working because they are scarce but have multiple purposes that can be fulfilled.
