At the convergent boundary, the plates collide when you press play.
According to the map, mountains are formed at the convergent boundary.
The highest elevation part of the continent contains continental sediments.
The green color with white markings represents metamorphic rock.
Once you clicked "start" at the divergent boundary, the original continent split into two continents and each continued to move away from the other.
At the divergent boundary, new rock is being formed from the magma.
The symbol that represents volcanoes is a red triangle.

10. Explain why convergent boundaries have more metamorphic rocks while divergent boundaries have more igneous rocks.
*
10. Convergent boundaries have more metamorphic rocks because these boundaries involve the collision or subduction of tectonic plates. When two plates collide, immense pressure and heat build up, causing the rocks to undergo chemical and structural changes. This process, known as metamorphism, leads to the formation of metamorphic rocks.
Divergent boundaries, on the other hand, have more igneous rocks because these boundaries involve the separation or divergence of tectonic plates. As the plates move apart, magma from the mantle rises to fill the gap and solidifies on the Earth's surface, forming igneous rocks. This process, known as volcanic activity, is common at divergent boundaries and results in the formation of igneous rocks.
