Answer and Explanation:
Although it is a recent technology, drones, or flying robots, are used in agriculture for a certain time, as they are able to do jobs with high precision providing benefits not only to the agricultural sector, but to the environmental sector as a whole. Drones can be great allies in the fight against climate change, through activities such as:
- Locate fire outbreaks: Whether in the fields or in the forest, when drones fly over areas, they can catch fire outbreaks, or areas that have great fire potential, allowing the fight against these fires to be carried out early, reducing the risks of deforestation and the emission of gases that stimulate climate change
- Decrease in the use of pesticides: Drones are able to spray agricultural areas with a smaller amount of pesticides. This, in addition to making production healthier and saving costs, allows the environment to have less impact and be less degraded.
- Check areas that need and go through a reforestation process: Deforestation is one of the major providers of climate change and to reverse this situation, drones can be used to identify areas that need reforestation quickly and accurately by quickly mapping the topography of the region to carry out analyzes that show the best way to reforest.
Answer:
Earth seismic waves creates vibrations and makes the plate move, it leads to splitting and breaking of the rocks.
Explanation:
- First, when the crust is broken due to forces of folding and faulting processes, the stress extends towards the rocks and which if prolonged can lead to snapping and breaking of the rocks in their new position.
- This process leads to vibration due to the release of the seismic waves. The fault created a fracture in the rocks and thus energy is released from within.
After the independence of many African countries (not all, for example, Ethiopia was never really colonized), the countries struggled both politically and economically - even more than before the independence.
A huge reason for that is that the countries were not formed along the ethnic lines, but instead they were divided by the Europeans among themselves, so when the independence was gained, there were many internal conflicts between the ethnicities and religions.
One example for this was the Rwandan Genocide - a result of the conflict between the Hutu and the Tutsi.
