Snow avalanches can be compared to landslides. Loose-powder avalanches move like a flow and slab avalanches move like a slide.

<h3>What is Avalanches?</h3>

Avalanches can start spontaneously, as a result of causes like increasing precipitation or decreasing snowpack, or by outside forces like people, animals, and earthquakes. Large avalanches can catch and move ice, rocks, and trees. They are mostly made of rushing snow and air.

The two main types of avalanches are slab avalanches, which are built of tightly packed snow and are caused by the collapse of a weak snow layer beneath them, and loose snow avalanches, which are made of looser snow. Avalanches typically accelerate quickly after being triggered and increase in bulk and volume as more snow is gathered. A powder snow avalanche could emerge if an avalanche moves quickly enough to mix part of the snow with the air.

Describe the formation, characteristics, and minerals present of the following rocks:
SOVA2 [1]

Explanation:

Serpentine

  • Formation: it forms through serpentinization, a geological low-temperature metamorphic process where low-silica mafic and ultramafic rocks are oxidized and hydrolyzed with water into serpentinite.
  • Characteristics: rich in magnesium and water, light to dark green, greasy-looking and slippery feeling. It can resist the transfer of heat. A source of asbestos, architectural stone, ornamental stone, gem material
  • Minerals present: it follows the formula (X)2-3(Y)2O5(OH)4 where X  can be magnesium, iron, nickel, aluminum, zinc, or manganese; and, Y will be silicon, aluminum, or iron.

Green Schist

  • Formation: they form by regional metamorphism of mafic igneous rocks through depth of burial, and proximity to batholiths.
  • Characteristics: The green is due to abundant green chlorite
  • Minerals present: actinolite and epidote mainly, but they can also include quartz, orthoclase, talc, carbonate minerals, and amphibole.

Basalt Pillow

  • Formation: it forms when lava of basaltic compositions erupted underwater. The rapid cooling of the lava forms the pillow-shaped bodies.
  • Characteristics: they are volcanic igneous rocks, very dark, almost black color.
  • Minerals present: Basalt has a lower percentage of silica and a higher percentage of iron and magnesium than other volcanic rocks.

Umber

  • Formation: it develops in Cyprus massive sulfide deposits.
  • Characteristics: is not one precise color, but a range of different colors, from medium to dark, from yellowish to reddish to grayish depending on the iron oxide and manganese in the clay
  • Minerals present: contains iron oxide and manganese oxide and sulfide precipitates like pyrite.

I hope you find this information useful and interesting! Good luck!
