Crevasses can form in several different ways. Transverse crevasses are transverse to flow and form where steeper slopes cause a glacier to accelerate. Longitudinal crevasses form semi-parallel to flow where a glacier expands laterally. Marginal crevasses form from the edge of the glacier, due to the reduction in speed caused by friction of the valley walls. Marginal crevasses are usually largely transverse to flow. Moving glacier ice can sometimes separate from stagnant ice above, forming a bergschrund. Bergschrunds resemble crevasses but are singular features at a glacier's margins.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What kind of crevasses form where glaciers contract laterally?
Ah, so.. unanswerable

If a state party's withdrawal is successful, its obligations under that treaty are considered terminated, and withdrawal by one party from a bilateral treaty of course terminates the treaty. When a state withdraws from a multi-lateral treaty, that treaty will still otherwise remain in force among the other parties, unless, of course, otherwise should or could be interpreted as agreed upon between the remaining states parties to the treaty.[citation needed]

Ah, so.. terminated

At the time of the Roman Empire, about two thousand years ago, various tribes, which spoke Celtic dialects of the Insular Celtic group, were inhabiting the islands. The Romans expanded their civilisation to control southern Great Britain but were impeded in advancing any further, building Hadrian's Wall to mark the northern frontier of their empire in 122 AD. At that time, Ireland was populated by a people known as Hiberni, the northern third or so of Great Britain by a people known as Picts and the southern two thirds by Britons.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What year did the British build Hadrian's Wall?
Ah, so..
unanswerable
