b) Costa Rica
c) Spain
d) Cuba
b. a low-lying region where Precambrian rocks are covered by Phanerozoic sedimentary strata
c. a region of compressed rock located behind a volcanic arc at a convergent continental margin
d. synonymous with craton
Answer:
The correct answer is D. Synonymous with craton
Explanation:
Craton is referred to as a large immobile block of earth crust composed of ancient crystalline basement rock and have deep lithosphere roots that extends deeply into the earth's mantle.
Cratons are often seen as shields because the basement rock crops out at the surface, and in platforms, the basement is overlaid by sedimentary rock.
Geographically, a shield and a surrounding platform together are synonymous with craton.
b. Humans build sea walls, which prevents seawater from entering aquifers.
c. Humans line and seal wells to prevent pollutants from entering an aquifer.
d. Humans prefer to use lake water as a source for drinking water rather than aquifers.
Answer:
a. Humans build roads, which prevents rainwater from replenishing aquifers.
Explanation:
This is because an aquifer is a body of rock that holds water or ground water and can readily transmit this water to Wells and springs. But human activities like building of roads has affected this. During road construction, rocks are broken down and ground water are depleted, as the roads are built, rain water will not be able to sink down to the ground rather will be on the tilled road which prevent it from getting to aquifer.

They are both necessary for organisms to survive.
To calculate the noon sun's angle above the horizon at Placerita Canyon, identify today's date and find the corresponding solar declination using the analemma. Next, calculate the arc distance (AD) by subtracting this declination from 34°N, and finally subtract the AD from 90° to get the solar altitude (SA). This gives you the sun's angle above the horizon at noon.
To calculate the angle of the noon sun above the horizon at a location of approximately 34°N latitude, given that the solar altitude (SA) is 90º minus the arc distance (AD). Start with the latitude of 34°N. Identify today's date and find the corresponding declination of the sun using the analemma. Subtract this value from 34°N (or vice versa depending on which is greater) for the AD. Finally, subtract the AD from 90° to get the SA.
For example, if today's declination of the sun was 23°N: AD = 34°N - 23°N = 11°, then SA = 90º - 11º = 79º. So, at noon the sun would be 79 degrees above the horizon at Placerita Canyon if today's date corresponds to a declination of 23°N.

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.

Geography lacks a distinct definition and agreement among geographers for the following reasons:
It is excessively extensive.
Geography is the study of everything on the surface of the world, which may be categorized as follows:
What is Physical Geography?
Therefore, the primary reason why it does not have a distinct description is that it is so wide and encompasses so many areas that a single word cannot possibly do it credit.
A region is an area of territory that has similar characteristics. An area may be characterized by natural or manmade characteristics. Language, governance, or religion, as well as woods, animals, or climate, may characterize an area. Large or small regions are the fundamental units of geography.
