I’m pretty sure the answer is A because carbon dioxide causes a solution to turn yellow and a solution that indicates no carbon dioxide would be blue instead of green.
Deforestation speeds up the process of soil erosion because trees are vital in keeping soil intact. The roots of trees help prevent soil erosion because they absorb the water in soil. If there are no trees to absorb the water, flooding can happen more. In turn, flooding can cause the soil to weaken and this can cause landslides and other natural disasters.
Advanced technologies like remote sensing have modified the way by which maps are constructed. Remote sensing is the procedure of collecting information about Earth with the help of instruments mounted on airplanes, satellites, or ships.
Remote sensing helps in monitoring and detecting the physical features of a region by determining its emitted and reflected radiation at a distance from the targeted region. Unique or specialized camera gather remotely sensed pictures of the Earth that assists the researchers in sensing the things about the Earth.
