A sharp pyramid-shaped mountain peak, formed when several cirques surround a single high mountain, is called a pyramidal peak.

A pyramidal peak, (also called glacial horn) is a sharply, pointed, pyramid-shaped mountain peak which results from the cirque (bowl-shaped basins) erosion caused by many glaciers that are carved away from a central point. The pyramidal peak has a feature of a sharp-edged summit, and steep sloping sides. Examples of pyramidal peak include; Mount Aspiring in New Zealand, Pilot Peak in Wyoming, United States and Nevado Las Agujas in Los Ríos, Chile.

the two answers are a, the population of birds with large beaks will increase on the island, and c, the trait for large beaks will be passed on to future generations through natural selection. the reason for that is because if the birds that have beaks developed for eating small seeds lose all of their food, they will go hungry and eventually starve because they physically cannot eat the large seeds, therefore making the population of large beaked birds higher. also, if the trait of large beaks are dominant on the island over small beaks, then over time the large beaked birds will reproduce more and more, while the smaller beaked birds will reproduce less and less because they can't survive with the food provided. that leads to the trait of small beaks disappearing and the trait of large beaks taking over the island.
