Answer:
One side of the moon always faces the earth, which is called synchronous rotation. In other words, the length of time the moon rotates or revolves around its axis is the same as the length of time it takes to orbit the earth... Therefore, our moon always has a side facing the earth, which we call the near side of the moon.
Answer:
The Mid Atlantic Ridge, like other ocean ridge systems, has developed as a consequence of the divergent motion between the Eurasian and North American, and African and South American Plates. In this way, as the plates move further apart new ocean lithosphere is formed at the ridge and the ocean basin gets wider.

Answer:
Protostars are difficult to observe because they are surrounded by cocoons of gas and dust.
The correct answer is - Layer 2 and layer 9 are the same relative age.
On this image we can see multiple layers that have been cut through and displaced by a fault. The layer 2 and the layer 9 despite not being at the same level, with level 2 being closer to the surface, while layer 9 deeper into the ground, we can still see signs that they actually have the same relative age.
We can notice that these two layers have the same relative age because of two things. The first thing is the index fossils, with both of these layers having the same fossils from the same geologic period. The second thing that gives us a clue is their composition which is pretty much identical, thus indicating of a same geological period.
