What does the law about superposition tell you about the relative ages of rocks?
a. that the deeper you go into rock layers, the older the rocks are
b. that the deeper you go into rock layers, the younger the rocks are***
c. that the oldest rock layer is always on top
d. that the oldest rock layer is always undisturbed
I don't think that it is D. I'm stuck between B and C. I'm not sure about A.

Neither b nor d is correct.
Beware of any answer that says "always" or "never."
So is it A?
Yes, A.
You're welcome.
Thanks ms. Sue
NOO IT GOT TAGGED BRUH AGAHFGSAD
Okay, thanks!
I only have 12 questions
Thx
You guys realize you can check your answer, right?
This is for connexes at the end of the semester
yes, it's A, lmao. isn't that kind of obvious?
single but smart kid is partially right. i got a 10/11 . its okay though thanks! it was the 11th question that i got wrong btw
Nevermind, I found the answer and it is D. But can someone check and make sure?
@single but smart kid. Thank you I got 100% for Connexus!
Which describes the law of superposition used to find the relative age of fossils in rocks?(1 point)
Fossils were formed during a time when chemical processes operated differently.
correct answer: Fossils were formed during a time when chemical processes operated differently.
Fossils in bottom layers are older than fossils in top layers.
Fossils in bottom layers are older than fossils in top layers.
Fossils inside a layer of a rock are older than the surrounding rocks.
Fossils inside a layer of a rock are older than the surrounding rocks.
Fossils of the same organism found at different locations formed in similar climates.
Which statement correctly describes the relative dating of rocks?(1 point)
It requires the use of fossils to determine the ages of rocks.
It can only be used for rocks more than a million years old.
correct answer:It describes the age of rocks compared to other rocks.
It provides an exact numerical age for rocks.
Use this sentence: Scientists found a fossil in a layer of rock that is 10 million years old.
Which is correct about the fossil's relative age?
The fossil is exactly 10 million years old.
The fossil must be younger than 10 million years.
The fossil cannot be dated with the given information.
correct answer:The fossil must be older than 10 million years.
Which method can be used to find the absolute age of fossils? (1 point)
correct answer: carbon-14 dating
correlation
law of superposition
carbon-12 dating
What is the difference between relative dating and carbon dating?(1 point)
correct answer: Relative dating is used in rock formations and fossils while carbon dating is used in organisms.
Relative dating is used in fossils only while carbon dating is used in rock formations and fossils.
Relative dating is used in rock formations and fossils while carbon dating is used in rock formations only.
Relative dating is used in rock formations only while carbon dating is used in rock formations and fossils.
What explains the existence of Mesosaurus fossils in both Africa and South America?
correct answer: The Earth’s continents were once joined together.
Earth’s natural phenomena, like floods, moved the fossils around the world.
The , Mesosaurus, was a good swimmer.
The Mesosaurus evolved independently on both continents.
Which is evidence of a supercontinent?(1 point)
A kind of plant fossil was discovered in a single location.
The characteristics of rocks on opposite sides of an ocean are different.
correct answer: The coastlines fit together like a puzzle.
One kind of animal fossil can only be found in Africa.
Which is done to collect evidence of continental movement?(1 point)
classifying plant fossils in Asia according to age
identifying the age of rocks in the seafloor
correct answer:mapping the ocean floor
finding new species of animals on each continent
Which data supports the seafloor spreading hypothesis?(1 point)
evidence collected by deep sea fishers
correct answer: bands of magnetic reversals in ocean rocks
discovery of fossils in the Himalayas
evidence collected by ocean swimmers
Which is explained by Hess’ seafloor spreading hypothesis?(1 point)
The ocean floor has thick layers of sediments and debris.
Earthquakes occur at the rim of the Atlantic Ocean.
correct answer: Fossils found on the ocean floor are much younger than those on continents.
It is difficult to study marine life in the extreme depths of the ocean.
Which statement describes the creation and destruction of ocean rock as they undergo seafloor spreading?(1 point)
New rock is created in ocean trenches and then turns to sediment on the ocean floor.
New rock is created in ocean trenches and is then reabsorbed at mid-ocean ridges.
correct answer: New rock is created at mid-ocean ridges and is then reabsorbed in ocean trenches.
New rock is created at mid-ocean ridges and then turns to sediment on the ocean floor.
