New Zealand,s varied topography and it's Sharp mountain peaks were created by two main forces.what are they

The two main forces that created New Zealand's varied topography, including its sharp mountain peaks, are tectonic activity and glaciation. Tectonic activity, including the collision of tectonic plates and earthquakes, has uplifted and folded the Earth's crust, creating mountain ranges and valleys. Glaciation, during the ice ages, sculpted the landscape by carving out deep valleys and shaping the sharp peaks we see today.
