"A pair of scissors consists of two pivoted blades. In lower-quality scissors, the cutting edges are not particularly sharp; it is primarily the shearing<span> action between the two blades that cuts the material. In high-quality scissors, the blades can be both extremely sharp, and tension sprung - to increase the cutting and shearing tension only at the exact point where the blades meet. The hand movement (pushing with the thumb, pulling with the fingers) can add to this tension. An ideal example is in high-quality tailor's scissors or shears, which need to be able to perfectly cut (and not simply tear apart) delicate clothes such as chiffon and silk."</span>
Answer:
It is the sense of "a nation as a cohesive whole, as represented by distinctive traditions, culture, and language." National identity may refer to the subjective feeling one shares with a group of people about a nation, regardless of one's legal citizenship status
the most common land use is for farm land
Answer:
See it in the explanation
Explanation:
1) Carbon moves from atmosphere to hydrosphere and biosphere in the process of photosynthesis and to lithosphere by deposition of dead bodies while from hydrosphere and biosphere, carbon can be move in the process of respiration by animals.
2) During respiration process which takes place in plants in which carbondioxide is released and by eating carbon containing food by animals. By decomposing the food, carbon is releases in the form of carbondioxide.
3) Carbon can be used by the marine plants in the process of photosynthesis and during the process of diffusion, carbon is also dissolve in water bodies.
4) When the plants and animals die, the carbon which is present inside their body is buried in the soil present at the bottom of the ocean and the shells and corels of some animals also contain carbon which is soon be the part of the lithosphere when they die.
5) After the decomposition of seashell, carbondioxide is produced because shells are made up of calcium carbonate.
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.
