Question: Thermally, a temperate glacier is at melting point throughout the year, from its surface to its base. The ice of a polar glacier is always below freezing point from the surface to its base, although the surface snowpack may experience seasonal melting. A sub-polar glacier includes both temperate and polar ice, depending on depth beneath the surface and position along the length of the glacier. In a similar way, the thermal regime of a glacier is often described by the temperature at its base alone. A cold-based glacier is below freezing at the ice-ground interface, and is thus frozen to the underlying substrate. A warm-based glacier is above or at freezing at the interface, and is able to slide at this contact. This contrast is thought to a large extent to govern the ability of a glacier to effectively erode its bed, as sliding ice promotes plucking at rock from the surface below. Glaciers which are partly cold-based and partly warm-based are known as polythermal.
Is there an answer to this question: What temperature makes a glacier polythermal?

Answer: partly cold-based and partly warm-based

Question: West was arrested again on November 14, 2008 at the Hilton hotel near Gateshead after another scuffle involving a photographer outside the famous Tup Tup Palace nightclub in Newcastle upon Tyne. He was later released "with no further action", according to a police spokesperson.
Is there an answer to this question: At what location did the incident leading to West's second arrest take place?

Answer: Tup Tup Palace nightclub

Question: While historically, symbiosis has received less attention than other interactions such as predation or competition, it is increasingly recognized as an important selective force behind evolution, with many species having a long history of interdependent co-evolution. In fact, the evolution of all eukaryotes (plants, animals, fungi, and protists) is believed under the endosymbiotic theory to have resulted from a symbiosis between various sorts of bacteria. This theory is supported by certain organelles dividing independently of the cell, and the observation that some organelles seem to have their own nucleic acid.
Is there an answer to this question: What far-reaching result do scientists think has come about from symbiosis with bacteria?

Answer: the evolution of all eukaryotes

Question: Temporal measurement, chronometry, takes two distinct period forms: the calendar, a mathematical tool for organizing intervals of time, and the clock, a physical mechanism that counts the passage of time. In day-to-day life, the clock is consulted for periods less than a day whereas the calendar is consulted for periods longer than a day. Increasingly, personal electronic devices display both calendars and clocks simultaneously. The number (as on a clock dial or calendar) that marks the occurrence of a specified event as to hour or date is obtained by counting from a fiducial epocha central reference point.
Is there an answer to this question: What physical mechanism is used to count periods longer than a day?

Answer:
unanswerable
