I believe flowing water would create erosion because tectonic plate movement and earthquakes are almost the same thing, and liquid rock is basically lava, and that only heats rock, rather than breaking it into smaller pieces, which is what flowing water does.
Hey there!
The answer is B, Pangaea. This was the name for the large continent that supposedly existed before we had all of our separate continents today (all of which were part of Pangaea).
Hope this helps
There are three sources of genetic variation: mutation, gene flow, and sexual reproduction. A mutation is simply a change in the DNA.
Answer:
- Land management
- Resource depletion
- Climate change
- Political issues
Explanation:
There are many challenges for agriscientist. Some of them are listed above. Here is the brief explanation:
Land management would be an issue because the human's population would be increased if not managed well. Therefore, we would need more land to provide them shelter. However, we know that growth follows geomatric pattern and fertile land would not be much available for crops cultivation.
Resource depletion is another challenge for agriscientists. We are utilizing our resources very fast to grow crops and increase yield. For example, groundwater is being pumped at very fast rate in many places/countries where surface water is limited. Similar is the case with other resources. We need to use our resources in a sustainable manner so that our future generations would not have to suffer.
Continous changing in cliamte is also a potential threat to modern generations for almost everything including agricture. As the temperature is rising, the crops would not be able to thrive harsh environmental conditions. Therefore, a major challenge would be to produce crops that can survive in hot temperatures.
We know that agri-industry is a multi-billion industry that is heavily driven by consumer habbits. Therefore, governments acts between consumer and industry, sometimes in positive ways but sometimes in negatives ways too. Therefore, it is also a challenge to have best policy which is not in favor of either group alone.
