Question

question 16
fossils help scientists construct earths geological timescale.
true
false

question 17
a principle that states that a fault or intrusion is younger than the rocks that it cuts through
the law of gravity
the law of conservation of mass
the law of cross - cutting
the law of waste

Explanation:

• For Question 16: Fossils are crucial for constructing the Geological Timescale. They provide evidence of past life forms and help in dating rock layers.
• For Question 17: The Law of Cross - cutting states that a fault or intrusion is younger than the rocks it cuts through. The Law of Gravity is about gravitational force, the Law of Conservation of mass is about mass in a closed system, and the Law of Waste is not a relevant geological principle here.

Answer:

• Question 16: True
• Question 17: The Law of Cross - cutting
