Answer

Convergent boundaries are called "destructive" due to crust subduction, while divergent boundaries are "constructive" due to new crust formation. These labels can be misleading as they oversimplify complex geological processes. Explanation 1. Define Convergent Boundaries Convergent boundaries occur where tectonic plates move towards each other, often resulting in one plate being forced below another (subduction), leading to the destruction of crust. 2. Define Divergent Boundaries Divergent boundaries occur where tectonic plates move apart, allowing magma to rise and create new crust, thus constructing new land. 3. Explain "Destructive" Label At convergent boundaries, crust is destroyed as it is subducted into the mantle, hence the term "destructive." 4. Explain "Constructive" Label At divergent boundaries, new crust is formed from rising magma, hence the term "constructive." 5. Discuss Misleading Aspects These labels can be misleading because they oversimplify complex geological processes. For example, not all convergent boundaries result in crust destruction; some may form mountain ranges without subduction. Similarly, divergent boundaries can also lead to seismic activity and volcanic eruptions, which are not purely constructive.
