<h3>Questions:</h3>
Brief discussion on the annual rainfall graph?
<h3>Answer: </h3>
Climate graphs depict the typical rainfall and temperature for a certain place. A line graph depicts the temperature, while a bar graph depicts rainfall. They're frequently depicted on the same axes, with the months of the year running parallel to the base.
Answer:
Non point sources
Explanation:
A point source is usually a single known source of a pollution such as emission of toxic fluids from a company directly into water bodies.
Runoff of eroded soil and chemicals such as fertilizers and pesticides from cropland, feedlots, logged forests, urban streets, parking lots, lawns, and golf courses are examples of non point sources as there is no main known source of the pollution.
Reddishness is due to iron content in the rock, simply the ferrous oxides.. mostly found on earth
Desertification occurs<span> due to a decrease in vegetation. This can </span>happen<span> naturally due to a drought or can be caused by human activities. The lack of plants can cause changes to the land. Plants help shade the soil, so when plants are removed, the soil will be exposed to the sun and will dry out more quickly. So, I would say C. An area of forest is clear cut.

On the geological maps in question, the cratonic basins that contain thick sequences of sedimentary rocks which overly the Precambrian basement, show the <em><u>youngest rocks</u></em> toward the center of the basin.
Geological maps are tools created and used by scientists to show the arrangement of the geological elements of a specific area. This can include:
- Rock types
- Cracks and faults
- Minerals
- Groundwater
- Ages
and much more, depending on the area and detail of the map created.
On a detailed geo-map, we can understand not only the area we are initially standing on but also where to find geological areas with similar sediment compositions and information on the age of the rocks. This is done due to the way the map stacks the units in terms of age, from the <u>youngest </u>at the <em><u>top </u></em>to the <u>oldest </u>at the <em><u>bottom</u></em>.
Cratonic basins are areas where geological elements are widely distributed and often filled with <u>shallow water </u>as well as <u>sedimentary rocks</u>. The rocks at the center of these basins show the <em><u>youngest</u></em> <em><u>rocks </u></em>at the center due to the previously mentioned <u>aging sequence </u>used by the <u>maps</u>.
