Answer

Answer:

  1. d
  2. c
  3. a

Explanation:

Step1: Analyze question 7

In a physical - change, the number of atoms of each type remains the same. No new substances (new types of particles) are formed.

Step2: Analyze question 8

C and D are in the middle of tectonic plates where there is less volcanic activity compared to plate - boundaries.

Step3: Analyze question 9

A is likely a mid - ocean ridge. New oceanic crust is formed at mid - ocean ridges, so the rocks there are the youngest on the ocean floor.
