Continent-continent convergence
The ice age and the subsequent sliding and melting of glaciers account for the mountain belt bounded on either side by craters
A mountain belt bounded by cratons typically forms as a result of the collision of tectonic plates. The initial collision leads to the formation of a convergent plate boundary, where intense compression causes the crust to thicken and form mountain ranges. Over time, erosion and other geological processes continue to shape the landscape and maintain the mountain belt.
The sequences of sedimentary rocks in cratons are typically thin and are relatively undeformed or gently warped. The sequences in mountain belts, meanwhile, are thick and extensively folded and faulted.

Cratons contain the ancient crust of igneous rocks.
cratons
Cratons are the stable interior parts of continents that have not been affected by significant tectonic activity for prolonged periods. They are typically composed of ancient and hard rocks, providing a stable foundation for the continent. Cratons are important for understanding the geological history and evolution of continents.
Cratons are stable, rigid blocks of the Earth's crust that are not typically prone to rift or shifting apart. However, under certain tectonic forces or geological processes, cratons can experience minor deformation or fragmentation, resulting in rifts or shifts along their edges. Overall, cratons are known for their stability and strength in the Earth's crust.

Areas of ancient continental interiors are called cratons.
cratons. These cratons are stable, ancient regions of the Earth's crust that hold some of the oldest rocks on the planet. They are often found in the interiors of continents like in Africa, Australia, and North America.
The stable core of a continent is the old, interior portion that has not experienced significant tectonic activity such as mountain-building or rifting for a long time. It consists of ancient, stable landmasses with low seismic activity and often includes cratons - the oldest and most rigid parts of a continent's lithosphere.
