The half-life of strontium-90 is 28.8 years. This means that if you have 60 strontium-90 atoms, in 28.8 years you will be left with 30 strontium-9

Answer 11

Trainman answered

Geologic Time Scale is the most relative time scale which records the time intervals on

Earth corresponding to each other in succession. It is used by geologists to
tell Earth’s history because it conforms to the order of Earth’s development
with respect to dividing time in terms of Earth’s biotic composition representing
various life forms.

Q16 Answer:
The half-life of strontium-90 is 28.8 years. This means that if you have 60 strontium-90 atoms, in 28.8 years you will be left with 30 stronium-90 atoms left.

Q17 Answer:
Because of how long the Earth has been alive, geologists use the geologic time scale to organize how far down the fossils or artifacts are. The geologic time scale shows the rocks and crust and how everything looked in the past times.

So I agree with you. It looks like 7 is wrong and ten is wrong. Work on those again ill be happy to check your answer. @100% answer, you shouldn't have gave him/her the answer. Kids need to learn how to do things by given help not the flat out answer. Please next time, dont do it. @Blue was the imposter, thank you for telling us but next time, try to figure it out, its like a videogame, you cant get the full answer, you just get hints. I know I know you alla re gonna say "but you're on this page, and, stop it your fake #faketeacher" but know, I'm on this page to help you all, and I'm not fake.

Layer D is older than layer B. If rock layers between B and D have eroded away, the boundary between B and D are called, an unconformity

QUESTION 15:

I believe that Layer D is older than layer B, even though it is shorter. Since the rock layers between B and D have deteriorated away, the dividing line between B and D would be called an unconformity. (I copy pasted so i changed it a bit, but change it yourself aswell just incase!!!)
