Antarctica, because it is nearest to the south pole, where least of the sun's light energy will concentrate, allowing most of the ice to freeze.
The Milky Way, so far, hasn’t gobbled up with any other
galaxies but scientists have found out that in the future, the Milky Way is
destined to be gobbled up or to be collided with its neighbor which is also
known as the Andromeda Galaxy.
The geometry term is actually "scale factor", which means the ratio of any 2 corresponding lengths in 2 similar geometric figures.
Answer:
In order to deposit 100 meters of limestone layer, it will take 6,451,600 years
Explanation:
Given that,
The rate of deposition carbonate sediments is 1.55 cm in 1,000 years
⇒ 1.55 cm = 1,000 years
⇒ 1 cm = 
⇒ 1 cm = 645.16 years
∵ 1 m = 100 cm
∴ 100 m = 100 × 100 cm
⇒ 100 m = 10,000 cm
So, the time it will take for carbonate to deposit 100 m thick layer of limestone will be-
⇒ 10,000 cm (100 meter) = 645.16 × 10,000 years
⇒ 100 meters = 6,451,600 years
Because the index fossils help with approximate yearing and rock layers tell which is older and ypunger
