Oh, I love a good ocean rock question! Well, it sounds like you're looking at the options and trying to choose the correct answer. Let me see if I can help you out.
Now, when it comes to those ocean rocks near mid-ocean ridges, they are actually younger and form through the cooling of magma. So, the correct answer is "They are younger and form through the cooling of magma." Don't worry, those rocks are just starting to rock out and show off their youthful charm!
The correct answer is: They are younger and form through the cooling of magma.
When trying to answer a question like this, it is helpful to have some background knowledge about mid-ocean ridges. Mid-ocean ridges are underwater mountain ranges that extend across the Earth's oceans. They are formed by tectonic activity where plates move apart and new oceanic crust is created.
Knowing this, we can deduce that ocean rocks found near mid-ocean ridges are likely to be part of the newly formed oceanic crust. As the plates move apart at mid-ocean ridges, magma rises from below the Earth's surface and solidifies to form new rocks. These rocks, known as basalt, are rich in iron and magnesium and are typically dark in color.
Since these rocks are formed from the cooling of magma at mid-ocean ridges, they are younger than other rocks found in the ocean crust. This is because they have been recently created and have not had as much time to undergo weathering and erosion compared to older rocks.
Therefore, the correct description of ocean rocks found near mid-ocean ridges is that they are younger and form through the cooling of magma.
