If all objects have some gravitational force then why don’t objects on earth move towards each other?
Mekhanik [1.2K]

<u>Answer:</u>

<em>The appropriate response is gravity: an undetectable power that pulls objects toward one another.</em>

<u>Explanation:</u>

Thus, the closer items are to one another, the more grounded their gravitational draw is. Earth's gravity originates from all its mass. <em>All its mass makes a consolidated gravitational draw on all the mass in your body.</em>

The power/mass proportion is the equivalent for each. A straightforward guideline to hold up under as a primary concern is that all items <em>(paying little heed to their mass)</em> experience a similar increasing speed when in a condition of free fall.

<em>At the point when the main power is gravity, the speeding up is a similar incentive for all articles. On Earth, this speeding up worth is 9.8 m/s.</em>

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!
