Answer:
150 million years old
Explanation:
If we have an isotope that has a half-life of 50 million years, we need just need to divide the numbers in order to get to one eight of the full number, than multiply it by 50 million in order to get the result.
If one half is 50 million years, than dividing one more half, which will gives one fourth of the total, will brings us to 100 million. Dividing the one fourth by two will leads to the one eight of the full number, and adding 50 million more years, we get 150 million years. So the rock in question has 150 million years of age.
Development that provides sufficient resources for MDCs while improving the economic conditions of LDCs
<span>The features that might allow
you to identify Upwarped Mountains is that the altitude is greater than the
land. It has a high elevation and also high relief compared to other mountains
and it was formed through sediments that continuously stretch or tear.</span>

B. Subduction
Explanation:
Subduction is one of such processes that causes thick sequences of sedimentary layers to accumulate along the boundaries of continental and oceanic plates.
- Continental and oceanic plates meets at a subduction zone which is a convergent margin.
- At this zone, the dense oceanic plate subducts or dives into the weak and less dense asthenosphere below.
- As it subducts, the ocean floor sediments on top is peeled off and the slab of lithosphere pulls down.
- This causes an accretionary wedge between the two zones.
- Most the sediments will eventually get metamorphosed into a metamorophic rock.
