The answer is Up because <span>in a reverse fault, compression (plates crashing together) it causes the hanging wall to move up. </span>
Abrasion takes place when stones become embedded in the glacier, as the glacier moves these stones slowly scratch along the surface of the ground below. Abrasian acts similarly to sandpaper, leaving a fairly smooth surface to the rock it has worn down.
Plucking takes place when the glacier has been fairly stationary for a while, so patches of rock from the ground below have become frozen to the glacier. When the glacier then moves, this patch of ground is forced out of the ground as it is attached to the glacier itself. As you can probably imagine, this leaves behind a much more jagged, uneven surface.
An unprotected traveler's blood would boil at normal body temperatures because the pressure is so low. Temperatures in the mesophere decreases with altitude, because there are few gas molecules in the mesophere to absorb the sun's radiation, the heat source is the stratosphere below. The air in the mesophere has extremely low density and as a result the air pressure is very low.
