True
Explanation
## Step 1This problem is about understanding a physical phenomenon that occurs when an external force impacts the surface of a glass. The impact creates stress lines on the surface. ## Step 2Initially, the part of the glass at the initial impact site fractures. This creates a series of ridges and valleys in concentric circles around the center of the glass. ## Step 3The primary fracture lines then radiate outward from the center of impact to the outer edge of these concentric lines. ## Step 4This process continues, creating secondary fracture lines that radiate out from the center of impact.
