Question

true/false questions

1. the principle of original horizontality suggests that sedimentary layers are usually deposited at an angle.

a. true b. false

1. geologists can determine the relative ages of rocks by examining their vertical arrangement.

a. true b. false

1. the principles of relative dating only apply to sedimentary rocks.

a. true b. false

1. paleontologists rely on relative dating to understand the evolution of life on earth.

a. true b. false

1. erosion can enhance the clarity of the rock record.

a. true b. false

Explanation:

1. The principle of original horizontality states sedimentary layers form horizontally, not at an angle.
2. Geologists use vertical rock arrangements (superposition) for relative age dating.
3. Relative dating principles apply to igneous/metamorphic rocks too (e.g., cross-cutting relationships).
4. Paleontologists use relative dating to order fossil life forms.
5. Erosion removes rock layers, reducing rock record clarity.

Answer:

1. b. False

3. b. False
4. a. True
5. b. False
