Answer:
Silicate-Oxygen tetrahedro
Explanation:
Silicate-Oxygen tetrahedro are the most abundant and basic structure of common minerals.
These are silicate minerals which formed to silicate rock forming mineral. These constitute about 90% of earth crust. Silica SiO2 consider as most common mineral on the surface of earth also known as Quartz. The the most andundant element in the earth crust is oxygen, mainly found in combine form.

<em><u>Answer:</u></em>
144 degrees
27 degrees
<em><u>Explanation:</u></em>
f) So angle EBD is angle 5, which is 36 degrees. Angle DBC is angle 1 and is 108 degrees. We need to find angle EBC or 5 + 1.
So we know that EBC is angle 5 + 1, we can do angle 5 plus angle 1 or:
36 degrees + 108 degrees = 144 degrees.
Angle EBC is 144 degrees.
g) So we know angle EBF or angle 4 + 3 is 117 degrees. We need to find angle ABE or angle 4. We know that angle 3 is 90 degrees because of BF is perpendicular to AC. So now we can find angle ABE or 4:
117 degrees minus 90 degrees = 27 degrees
Angle ABE is 27 degrees.
Along with the stars, Kristen shall also show effect of gas, dust and solar system in the galaxy.
<u>Explanation:</u>
Galaxy is a collection of various stars but these are bound to each other in a gravitational bound system. Along with the stars, the galaxy also consists of dust, gas and other kind of dark matter.
The solar systems are also consisted in the galaxy. According to the scientists, there are one hundred billion galaxies in the universe and all the galaxies consisting of a combination of all this.
