Which conclusion can be made when radial cracks from impact x on a glass stop at the radial cracks of impact b? a. impact x happened before impact b. b. impact b happened before impact x. c. the force of impact b caused the breaks in impact x. d. the force of impact x caused the breaks in impact b.

B. Impact B happened before impact X.

Explanation:

Radial fractures are the fractures which radiate out from the point of impact in the form of radiating lines. It originates on the opposite side of the impact. The original radial fracture will appear in a wavy line and the extensions of such fractures appear straight.

During the formation of fracture on the glass with multiple impacts. The fracture lines formed by the second impact stops where the line of fracture meet the fracture line caused by the first impact. These lines of fractures can be interpreted to determine that which impacted happened first.

In the given situation, radial cracks from impact X stops at the cracks of impact B. This indicates that impact B happened before impact X.

primary succession occurs in essentially lifeless areas regions in which the soil is incapable of sustaining life as a result of such factors as lava flows, newly formed sand dunes, or rocks left from a retreating glacier. secondary succession occurs

gold i'm pretty sure i might be wrong
