They were exposed to the same agents of weathering
The correct answer is A. the rocks are the same age.
Fossils can be defined as the preserved traces of animals or plants found inside rock.The importance of fossils is huge, because they can be involved in dating geological material. Fossils indicate which species were alive at the time the rock was formed. So, the same fossils can be found in rocks on different continents, representing the age of those rocks.
i think the answer is that the rocks have had been exposed to the same agents of weathering.
D. They were exposed to the same agents of weathering.
B) gravity, lichens and moss, tree roots
In this mountainous area of Canada, weathering of rocks occur due to the force of gravity which increases the speed of rolling rocks and causes weathering of rocks into small pieces. These rocks have hard surfaces so only moss and lichens grow on these surfaces. The reason behind the growth of moss and lichens is that they have not specialized root system like plants. Lichens also helps in the weathering of these rocks by secreting chemicals.
I guess it's Lowest
