Answer:
Option (1)
False
Explanation:
The mid-oceanic ridge is one of the main features in the divergent plate boundary. Seafloor spreading takes place along this ridge, where the lithosphere becomes thin because of the uprising magma. The magma erupts at the surface forming a ridge which is commonly known as the mid-oceanic ridge.
As the magma melts at this ridge due to the decompression process, it solidifies and forms young basaltic igneous rocks. These are geologically the youngest rocks. With the increasing distance right from the mid-oceanic ridge, the age of the rocks increases.
Thus, the correct answer is option (1).
At this mid-oceanic ridge, when the magma erupts at the seafloor, it is comprised of magnetic minerals, which shows a specific pattern in the orientation of the earth's magnetic polarity. This forms alternate stripes, that starts from the mid-oceanic ridge and eventually expand outward. This pattern of earth's magnetic polarity is found in all the mid-oceanic ridges on earth.
Hence the given statement is false.
Sorry don’t know what that is

Answer:
The correct answer is "(D) Process in which water and water vapor emerge from deep layers within and below the Earth's crust."
Explanation:
Outgassing is the release of a substance (usually gas) that was initially trapped in some material. When water and water vapor which was initially trapped from deep layers within and below the Earth's crust emerges, this process is referred to as outgassing.
