Answer:
They are youngest close to the ridges,
Explanation:
At the ocean ridges, there is divergence at their margins.
Therefore, new materials upwell from the mantle below to the surface.
- The basaltic materials cools and solidifies at the margin.
- This action forces the old lithosphere backwards as the plate pulls away.
- At the margin of the ridge, the rocks are younger.
- Away from the margin, the crust begins to grow older.
So, at the margin the age of the rocks are more younger than those away from the margin.
They weren't as accurate as they could be, in fact some were just based off of educated guesses.
One of the main reasons, I think, that they revolted was because the British had put a lot of taxes on the goods of the American colonists. One of the big things they taxed was tea. I think that if the British would have gone lighter on the taxes, especially the tea ones, the movement might have not happened.
Tea was a big thing at the time so obviously if they had to pay taxes for something they truly loved, it would make them upset.
I hope this helps, I’m not sure exactly when the question you’re asking is about but I tried :)
Because circumpolar constellations never rise or set, they provide reliable reference points for astronavigation. Knowing the circumpolar constellations in each hemisphere allows navigators to find their way using only the stars.
