Explanation:
There are several mountain building processes that are not associated with plate boundaries.
Block mountains for example does not require any of the condition at a plate margin to form. So far the crust begins to elongate by extensional forces, rock blocks drop and some other rise to form series of horsts and grabens.
The most prominent mountains that forms outside non-plate margins involves sedimentary rock formations.
Here, sediments accumulates within a basin where they get compacted and lithified. During episodes of regional uplift, the crust might rise to new levels and the basins would become elevated to towering peaks.
Halley — the traditional pronunciation of the name usually rhymes with valley — was born Nov. 8, 1656, in Haggerston, Shoreditch, London, England. His father was a prosperous soapmaker and property owner. Halley was tutored privately at home before entering St. Paul's School, where he excelled in mathematics and astronomy.
Halley entered Queen's College, Oxford, in 1673, when he was 17 years old. He brought with him a fine collection of astronomical instruments purchased by his father. While still an undergrad, he became a protégée of John Flamsteed, the Astronomer Royal.
