Question

Where would you be most likely to find the oldest rocks on Earth?

Answer 1

At the outer edges of ocean crust

Explanation:

The rocks found in continents are older and in some cases the oldest. The younger rocks are found in mid ridge of ocean. The oldest rocks can be found in ocean trenches that are very deep.

At the outer edges of ocean crust, oldest rocks can’t be found as relatively newer ones are formed continually and mostly found. So, different regions have different ages of rocks and needs to be explored properly.  

Answer 2

Answer:

at the outer edges of oceanic crust

Explanation:

• As the oceanic crust from the lava gets deposited in both the sides of the floor so this spreading of lava outward from the surroundings tends to accumulate and gets aligned with magnetic properties this basaltic layer of lava when solidifies gets converted into a rock mass and is deposited at the outer edges of the crust.

• As each year the earth repeats this cycle and recycles the old materials back to the origin and new rocks ar create from the deeps of the oceanic floor. And newer ones are found around the center of the mid-oceanic ridges.

• Thus places most likely to find the old rocks are near the shore of the continental crusts.
