How much do glaciers move in a year?
GeologyGlacial motion can be fast (up to 30 metres per day (98 ft/d), observed on Jakobshavn Isbræ in Greenland) or slow (0.5 metres per year (20 in/year) on small glaciers or in the center of ice sheets), but is typically around 25 centimetres per day (9.8 in/d). Do glaciers constantly move? Glaciers periodically retreat or

What roles did abiotic factors play in succession after the eruption?
GeologyAbiotic factors were critical to plant and animal survival and colonization. Wind played an important role in transporting spiders, insects, and seeds into the blast zone. Plant survivors, rocks, and landscape features acted as “nets” that caught windblown seeds. What roles did factors such as moisture and landforms play in succession after the eruption? What

What causes continental rise?
GeologyContinental rises form as a result of three sedimentary processes: mass wasting, the deposition from contour currents, and the vertical settling of clastic and biogenic particles. Where is the continental rise and how is it formed? Alluvial or sedimentary fans are shallow cone-shaped reliefs at the base of the continental slope that merge together, forming

How is Yule marble formed?
GeologyThe forces that created Yule Marble make it distinct from all other American marbles. It was formed by contact metamorphism, unlike Vermont marble and Georgia marble, which are the result of regional metamorphism, a process more associated with the orogeny and erosion of mountain ranges on a regional scale. Why Does Colorado have a lot
