C - A typical star i just took the test and it was correct
Answer:
Dentistry of gases and mass and distance from sun.
Explanation:
- Out of the 8 planets the earth is an only habitable planet in the solar system till date and thus is called as the blue planet as it has water as the source of life form.
- Other planets like the mars and Venus are likely that of the earth but have a certain amount of variation in their atmospheric composition and characteristics and thus they have different cycles.
- Thus like the variation of the sunlight in the earth equator and the poles, due to the more bulges to the equator areas and less of above.
- Similar is the variation in the gases and the density of the mass of the planets and other four-planet are gas giants and have there own atmosphere surrounded in thick layers.
C) The number of Bears with decrease.
The contaminated fish with cause the bears to be contaminated and die.
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.
