Answer:
Why the majority of species live on earth and not in the sea is one of the top questions of science. The following are some of the reasons some scientists quote:
- plants play a major role; plants need light for photosyntesis, there is little sun in the ocean except for shallow coastal areas; so, land is more productive than the cold, dark depths of the ocean;
- the co-evolution of plants and insects has also played a role in the birth of so many new species; the vast majority of plants on Earth are flowering plants and 80 percent of all species are insects.

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).
