Where slopes are steep, contour lines are closely spaced.
The slope is determined by the distance between contour lines; the greater the distance, the softer the slope.
<h3>What is contour line?</h3>
- A contour line of a two-variable function is a curve that connects points of equal value and along which the function has a constant value.
- It is a portion of the plane in the three-dimensional graph of the function f.
- On a map, you'll notice three different types of contour lines: supplemental, index, and intermediate. The thickest contour lines are called index lines, and they are typically numbered at some point along their length.
- There are numerous types of landforms on the surface of the earth, and they range greatly in height and elevation.
- The elevations of these surface features are depicted on contour maps, allowing you to view a two-dimensional map and imagine the Earth in three dimensions.

Agriculture and fisheries are highly dependent on the climate. Increases in temperature and carbon dioxide (CO2) can increase some crop yields in some places. But to realize these benefits, nutrient levels, soil moisture, water availability, and other conditions must also be met. Changes in the frequency and severity of droughts and floods could pose challenges for farmers and ranchers and threaten food safety.<span> Meanwhile, warmer water temperatures are likely to cause the habitat ranges of many fish and shellfish species to shift, which could disrupt </span>ecosystems<span>. Overall, climate change could make it more difficult to grow crops, raise animals, and catch fish in the same ways and same places as we have done in the past. The effects of climate change also need to be considered along with other evolving factors that affect agricultural production, such as changes in farming practices and technology.

Soil type will influence crop cultivation because different crops prefer different soils.Clay soils with their high water retention are well suited to rice whilst sandy soils with good drainage are good for root vegetables. Soil type can be influenced through the input of lime, clay or fertilizer but this can only make limited differences.
Every major advance in agriculture<span> has allowed global </span>population<span> to increase. Early farmers could settle down to a steady food supply. Irrigation, the ability to clear large swaths of land for farming efficiently, and the </span>development<span> of farm machines powered by </span>fossil<span> fuels allowed people to grow more food and transport it to where it was needed.</span>
The creation of the Salton sea was a result of an accidental diversion of the Colorado River.
