Match each statement based on the type of dating it is describing, either Relative Age or Absolute Age. (1 point per match)(4 points)
The cake layer on the bottom of the cake is older than the cake layer on the top of the cake.
Today, my dog Max turned 5 years old.
In a rock, a Carbon-14 isotope underwent one half-life therefore the rock is 5,730 years old.
The highest/top sedimentary rock layer at The Grand Canyon is younger than the rock layers below it.
Relative Age:
- The cake layer on the bottom of the cake is older than the cake layer on the top of the cake.
- The highest/top sedimentary rock layer at The Grand Canyon is younger than the rock layers below it.
Absolute Age:
- Today, my dog Max turned 5 years old.
- In a rock, a Carbon-14 isotope underwent one half-life, therefore the rock is 5,730 years old.
Statement 1: Relative Age
Statement 2: Absolute Age
Statement 3: Absolute Age
Statement 4: Relative Age
To determine which statements correspond to Relative Age or Absolute Age dating, we need to understand the concepts.
Relative Age Dating: This method determines the age of an object or event in relation to other objects or events. It relies on principles such as the Law of Superposition, which states that in a sequence of undisturbed rock layers, the younger rocks are on top of older rocks.
Absolute Age Dating: This method provides an actual age in years for an object or event. It often involves the use of radiometric dating techniques, such as measuring the decay of isotopes within rocks or organic materials.
Now let's match each statement to the type of dating:
1. "The cake layer on the bottom of the cake is older than the cake layer on the top of the cake."
This statement refers to the Law of Superposition, which is a principle of Relative Age Dating. It indicates that the older layer is at the bottom.
2. "Today, my dog Max turned 5 years old."
This statement provides an actual age in years, making it an example of Absolute Age Dating.
3. "In a rock, a Carbon-14 isotope underwent one half-life, therefore the rock is 5,730 years old."
This statement involves radiometric dating using Carbon-14 isotopes and measuring half-life. So, it represents Absolute Age Dating.
4. "The highest/top sedimentary rock layer at The Grand Canyon is younger than the rock layers below it."
This statement again refers to the Law of Superposition, indicating Relative Age Dating. The higher rock layers are younger than the lower layers.
Now, let's match the statements:
- Statement 1: Relative Age Dating
- Statement 2: Absolute Age Dating
- Statement 3: Absolute Age Dating
- Statement 4: Relative Age Dating
Therefore, the matches would be as follows:
Statement 1: Relative Age Dating
Statement 2: Absolute Age Dating
Statement 3: Absolute Age Dating
Statement 4: Relative Age Dating
