← GeographyWhich consequence results when heavy tephra accumulation exceeds tree's limits?
A)Crown breakage via gravitational stress✓
B)Reduced photosynthesis limits carbon
C)Elevated thermal plant cellular damage
D)Accelerated stem vascular cambium disruption
💡 Explanation
Heavy tephra accumulation causes crown breakage because gravitational stress from the additional weight overcomes the branch's structural integrity. Therefore, branches break rather than experiencing thermal or vascular damage, due to direct weight.
