The answer is: <u>Land Use</u>
Answer:
C. A mass of air that is similar in temperature and humidity
Explanation:
An "air mass" refers to a big volume of air that is characterized by having similar or uniform "temperature" and "humidity"<em> (moisture).</em> They come from different source regions, thus they are classified accordingly.
The<em> "cold air masses"</em> come from the <u>polar area</u>s while the<em> "warm air masses"</em> come from the<u> tropical areas.</u> An air mass may cause a storm, for example, when an air mass moves to a new region and confronts another air mass there with a<em> different humidity and temperature</em>.
The map of the United States that is representing the soil erosion, shows us a trend that the soil erosion is the biggest in the areas where there is the most agricultural activity in the country, mostly the Midwest, the southern part, and the lowlands east of the Appalachians.
It is no wonder that the areas where there is the highest agricultural activity have the highest wind and water erosion. What is now agricultural land, in the past had a natural protection of wild plants, but now it doesn't.
The constant plowing of the soil results in making the soil much more loose several times in a year, sot he wind is able to pick up particles easily, and the water is able to easily move the top layers.
The heavy usage of pesticides, herbicides, fungicides, and artificial fertilizers are also making the soil very loos, so the erosion has big effect.
Depending on the irrigation method, it can have a big effect, especially if it is irrigation through ditches, as the water will be pushing from one side and moving toward the other side, moving the top soil with it.
The two types of map that can be used to measure change spatial change over time are:
- Spatialtemporal visualization
- Analysing Spatio-Temporal Data
Advantages of these map is that it posses an advantage which help in revealing overall tendencies as well as movement patterns and this makes it to be better than the traditional visual representations.
Disadvantages of this map is that the analysis can be challenging because of the unlimited directions by space which could involves North, South and the rest.
<h3>What is mapping?</h3>
Mapping can be regarded as the transformation which involves the taking of points of one space with respect to the other.
However, the maps that can be used to measure change spatial change over time are:
- Spatialtemporal visualization
- Analysing Spatio-Temporal Data
