Plate tectonics are important to geoloigists because they explain how the continents make up the earths crust.
Answer: See below
Explanation:
p-(p+20) = 4(p-5) + 3p
p-p-20 = 4p - 20 + 3p
-20 = 7p -20
40 = 7p
40/7 = p
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!
False, now good job to me and ya'll can really tell me thanks or helping yall out to the wrong answer.
Answer:
The day moon is a product of the sunlight reflected on the satellite. Sometimes, we can see the moon during the daytime, because depending on the moon´s position, sunlight is reflected on the satellite, allowing us to see from the Earth during the day.
Explanation:
The moon is a dull satellite that has no light by itself. The only way we can see it is through the reflection of the sunlight on this body. This effect also depends on the moon´s position concerning the Earth and to the sun. It is a natural product of the rotation and translation movement of the Earth and the moon.
This effect is related to the moon phases: new, first quarter, full and third quarter. During the daytime, we can see the waxing and waning gibbous phases because the moon is placed in a way that sunlight reaches it and reflects its shape. When this effect occurs, we can see that the star and the satellite get more separated each day. The moon gets to hide in the skyline later than the sun. This is why sometimes we can see the moon during the evening or the day.
