What will happen where two continental plates collide at a convergent boundary

Answer 1

When two continental plates collide at a convergent boundary, several things can happen depending on the specific circumstances:

1. Mountain formation: The collision between two continental plates often leads to the formation of large mountain ranges and the uplift of rock layers. As the plates collide, the crust is compressed and folded, causing the Earth's crust to buckle and form mountains. Famous examples of such mountain ranges include the Himalayas formed by the collision of the Indian and Eurasian plates.

2. Earthquakes: When two continental plates collide, massive amounts of energy are released in the form of earthquakes. The stress and pressure build up over time until the accumulated strain is released through a sudden release of energy in the form of seismic waves.

3. Earth's crust disruption: The collision between two continental plates can cause the crust to thicken and undergo deformation. The crust may fold, fracture, or break apart, forming faults and fractures, which can lead to the formation of rift valleys or fault zones.

4. Subduction initiation: In some cases, one continental plate may be forced beneath the other, initiating subduction. However, unlike oceanic plates, which are denser and often result in subduction beneath a continental plate, continental plates have similar densities, making subduction less likely.

5. Volcanic activity: Although less common at convergent boundaries between continental plates, volcanic activity can still occur. If one of the colliding plates has oceanic crust, subduction may occur and melt the subducted crust, leading to the formation of volcanoes. These volcanoes are usually characterized by explosive eruptions and the formation of volcanic arcs.

It is important to note that the collision between two continental plates is a slow and gradual process that happens over millions of years. The specific outcome of their collision depends on factors such as the angle and speed of the collision, the composition and thickness of the plates, and the presence of other geological features in the area.
