In the past century or so, astronomy has been broadly split into two camps — observational astronomy (using telescopes and cameras to collect data about the night sky) and theoretical astronomy (using that data to analyze, model and theorize about how objects and phenomena work)

Well observational and theoretical astronomy are the two fields of professional astronomy. Observational astronomy is concerned with gathering information from observations of celestial objects. The data is then examined using fundamental physics principles.

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.

do you think Churchill's quote accurately describes the relationship between Hitler and Chamberlain? why why not.
salantis [7]

The correct answer to this open question is the following.

Churchill’s quote that accurately describes the relationship between Hitler and Chamberlain is the following: "You were given the choice between war and dishonor. You chose dishonor and you will have war."

Neville Chamberlain had been the British Prime Minister at the beginning of the war. Winston Churchill seriously opposed Chamberlain's policy of appeasement that grated Nazi leader, Adolph Hitler, many concessions to avoid another war. Chamberlain had accepted to grant Hitler some territories to appease Hitler's ambition and Winston Churchill found this intolerable and in the end, he was right. Hitler's troops invaded Poland on September 1m 1939, and this represented the beginning of World War II.
