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.

At the bottom of the food chain, green phytoplankton is eaten by krill and shrimp. The krill and shrimp are later eaten by squid, whales, and fish. Later, seals, penguins and birds eat the squid. Finally, killer whales/orca eat squid as well.

This is what I found. Raindrops form when microscopic water droplets bump into each other in clouds. the more turbulent the clouds the bigger the raindrops get
The length of daylight and nighttime are of equal length on an equinox because the center of the sun spends a roughly equal amount of time above and below the horizon at every location on the Earth.
Answer:Pastoral farming can be advantageous as land that may be unsuitable for crops can be utilized. However, a downside can occur (and has a number of times in the past) with the spread of disease from area to area just for 1 pro and cokn
