Answer:
Option (2)
Explanation:
The mid oceanic ridge is the region along which two plates moves away from one another. This occurs in the divergent plate boundary. The magma, during this type of plate motion, comes out to the surface of the ocean floor and solidifies immediately due to the lowering temperature, giving rise to the formation of basaltic rocks.
The solidification age refers to the time when the magma last crystallized as it ejected at the ocean floor.
According to the given condition, the magma last solidified nearly 10,000 years back in the mid oceanic ridge, which are considered to be the youngest rocks found along the mid oceanic ridge.
Thus, the correct answer is option (2).
The slopes of most cinder cones are usually about 30 degrees because that is the angle of repose, which is the slope at which the loose cinder can stand in equilibrium.
The cinder cones vary significantly in height, from just a few meters of height to few hundred meters.
They are numerous around any volcano, and lava can come out of them or may flow below them.
Seven continents are in this world
The first evidence was presented by Wegner when he hypothesized that all the continents once formed a single land mass called the Pangea before drifting apart. So, to fill in the blank, it would be that '<em /><em>neighboring continents [are] like jigsaw puzzle pieces</em>'
