Aseamount chain is choose one:
a. an elongate, relatively narrow series of basaltic volcanoes that traverse the ocean floor, rising to a relief of 2 to 2.5 km above the surrounding abyssal plain.
b. an elongate arc where ocean depths reach as much as 12 km, bordering chains of volcanoes at subduction zones.
c. a region of oceanic crust where earth's magnetic field appears to be either slightly stronger or weaker than expected.
d. an elongate series of former volcanic islands that poke up from the ocean floor. esc

elongate series of former volcanic islands that poke up from the ocean floor

Explanation:

Option (D)

Explanation:

Sea mount chains are usually defined as a large and elongated, distinct geological landforms that are formed below the ocean surface. These are typically formed from the ancient extinct underwater volcanoes, that are basaltic in origin. They rise up from the ocean floor upto various heights but the waves in the oceans continuously weathers, erodes and configures them. These are basically formed in the spreading zones and the mid oceanic ridges.

Thus, the correct answer is option (D).

the following sets of characteristics describe what we know about the outer plants is c. rocky surface, closet to the sun and larger in size
