Question

1. choose the correct answer. this technique measures carbon 14 in dead organisms.

• radiocarbon dating
• potassium-argon dating
• date markers
• stratigraphy

1. choose the correct answer. what technique is used in the dating of certain types of rocks?

• radiocarbon dating
• dendrochronology
• potassium-argon dating
• stratigraphy

Explanation:

Question 7

Radiocarbon dating measures the amount of carbon - 14 in dead organisms to determine their age. Potassium - Argon dating is used for dating rocks (not organisms), date markers are not a dating technique in this context, and stratigraphy is about rock layers' study for relative dating. So the correct option is Radiocarbon dating.

Potassium - Argon dating is a technique used for dating certain types of rocks. Radiocarbon dating is for organic materials, dendrochronology is for tree - ring dating, and stratigraphy is for relative dating of rock layers (not absolute dating of rocks in the way Potassium - Argon does). So the correct option is Potassium - Argon dating.

Answer:

A. Radiocarbon dating
