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.

Answer:
I dont know to much about Cali but here is what I know.
Explanation:
Will California eventually fall into the ocean?
No, California is not going to fall into the ocean. California is firmly planted on the top of the earth’s crust in a location where it spans two tectonic plates. The San Andreas Fault System, which crosses California from the Salton Sea in the south to Cape Mendocino in the north, is the boundary between the Pacific Plate (that includes the Pacific Ocean) and North American Plate (that includes North America). These two plates are moving horizontally, slowly sliding past one another. The Pacific Plate is moving northwest with respect to the North American Plate at approximately 46 millimeters per year (the rate your fingernails grow). The strike-slip earthquakes on the San Andreas Fault are a result of this plate motion. There is nowhere for California to fall, however, Los Angeles and San Francisco will one day be adjacent to one another!

Answer:
Kilimanjaro
Explanation:
The name of Africa's tallest peak (19,341 feet above sea level) comes from two local languages: Swahili and Chagga. When combined, the words translate to "Shining Mountain" or "White Mountain." Alternate names given to Kilimanjaro throughout history translate to "Mountain Where Birds Cannot Fly" and "Mountain of Silver Moons." The Chagga people believe that a spirit lives atop the peak and will cause sickness to some who climb. Anthropologists think this is likely their method for explaining altitude sickness, caused by attempting to climb Kilimanjaro too quickly.
Answer:
A
Explanation:
The physical environment has a massive effect on human activities. Throughout history the impact of the effect of the physical environment has changed, but the influence has always been there. Some ways in which the physical environment affect humans are:
- weather and climate
- natural disasters (volcanic eruptions, earthquakes, tsunamis)
- terrain
Human activities also have a significant impact on the physical environment. Some examples of ways that humans affect the physical environment are:
- deforestation
- extraction of resources
- anthropogenic climate change
- modification of topography
- contamination of the seas
