Rate of subduction is one factor that distinguishes the three phases of the Cordilleran Orogeny True False
katrin2010 [14]

Answer:

True

Explanation:

The Cordilleras have one major factor that distinguishes them from the other mountain ranges, the three phases of its orogeny. Unlike most of the mountains in the world that have been created by a single orogenic process, that is not the case with the Cordilleras. There have been three consecutive orogenies, the Nevadan, Sevier, and  Laramide orogenic process that created the Cordilleras, thus making them a unique mountain range.

Which statements describe gridlines on a map? Check all that apply.
sergij07 [2.7K]

<u>From the given options which may suitably apply to the description of grid-lines of the map are </u>

  • They are measured in degrees
  • They set up a reference system
  • They divide Earth into four equal parts

Answers: Options A, B and E

<u>Explanation: </u>

Option A describes that the grid-lines of the map are measure in degrees, which are very true as the grid are lined with angular measurement which thus be done in unit of angles and is in degrees only.

Option B says it develops the reference system which specifies about the area being plotted are grid depending upon the size which sets up the referential system of enumeration.

Option E is true as the world or the Earth has been divided into 4 equal parts through the Prime Meridian as the longitudinal line and Equator as the latitudinal line.

1. Calculate the angle of the noon sun above the horizon right here at Placerita Canyon, which is at ~34N. Use the analemma on
vovikov84 [41]

Answer:

The latitude at which the noon sun is directly overhead is defined as the sun's declination. For example, if the sun appears directly overhead at 20°N latitude, the sun's declination is thus 20°N. Figure 7-3, known as analemma, shows the declination of the sun throughout the year. Thus, if you would like to know where the sun will be directly overhead on September 20, you can look on the analemma and find that it will be at 1°N. Given the declination, the noon sun angle at a particular latitude on any given day can be calculated.

Figure 7-3. The analemma, a graph illustrating the latitude of the overhead noon sun throughout the year.

Figure 7-4 shows that for each degree of latitude that the place is away from the latitude where the noon sun is overhead (declination), the angle of noon sun becomes one degree lower from being vertical (or 90°) above the horizon. Noon sun angle for any given latitude on any given day can be calculated using the following equation:

Noon Sun Angle = 90° - (Latitude +/- Declination)

In this equation, use " - " when the latitude and declination are on the same hemisphere and use " + " when they are on the opposite hemispheres. For example, on April 11, the declination is 8°N, the noon sun angle at Springfield, Illinois (40N) on April 11, therefore, should be 58° (90° - (40°N - 8°N).

Figure 7-4. Noon sun angle calculation. The example in this figure illustrates how to calculate the noon sun angle for a city 40° north of the equator (like Springfield, Illinois) on December 22.
