(1) The spectrum of light used to determine direction is called redshift. Redshift occurs when electromagnetic radiation—usually visible light—emitted or reflected by an object is shifted towards the less energetic ("red") end of the electromagnetic spectrum due to the Doppler effect or other...

5. The greater the distance to a galaxy, the greater its redshift. That's what Hubble's Law is all about.

Magmatic fractionation/differentiation is known today as Bowen's Reaction Series. The progression in the series explains why the first lavas from a volcanic vent are rich in iron, magnesium, and calcium, are low in quartz (mafic), and are dark green to black and why the later lavas are lighter...

It's a 90-degree triangle, so the Pythagorean Theorum comes into play: c^2 = a^2 + b^2 Where C is the hypotenuse, A and B are the sides of the triangle (the 90-degree angle is between A and B). The shortest route is to go directly west, then directly north at 90-degrees, then the angled...

Okay, assuming that they aren't interacting... The local geology of the area affected by a seismic event changes the way that seismic energy is transmitted to a structure. For instance, if conditions are right, a phenomenon called "liquefaction" can occur. This makes loose sediments suddenly...

Hot, pressure environments of igneous rock (as opposed to hot, pressure metamorphic). Aquamarine gemstones belong to the prestigious beryl group of minerals. Beryl crystals are some of the precious gems that occur in nature. Igneous rocks facilitate the growth conditions for aquamarine...

I'm not sure that I can explain all eight, but I'll give you my best answers. A river valley is critical to early civilization because it provides direct food resources (fish, turtles, etc.), agriculture through diversion of river water (irrigation), faster, easier, and larger trade avenues...
