Explanation:
waterfalls are temporary features of rivers because stream erosion is greatest at waterfalls and rapids. The water that falls at the base of the waterfall erodes rock there, leaving the rock at the tops of the waterfalls to overhang. Overall, undermining causes waterfalls to recede farther upstream.
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>
