Answer:
Atmospheric Pressure and Winds
The heating of the Earth's surface and atmosphere by the sun drives convection within the atmosphere and ocean. This convection produces winds and ocean currents. The greater the pressure differences between a low-pressure area and a high-pressure area, the stronger the winds.
Explanation:
They lived in Latin and South America
i cant find where they came from but this is where they lived
Answer:
B. atmosphere: because the ash blocked more radiation than normal, not allowing it to reach the surface
Explanation:
The volcanoes are one of the major factors that shape the climate on Earth. Their influence can be more moderate and gradual, or it can very big and abrupt. The large volcanic eruptions manage to cause changes in the global climate very quickly. The reason for this is that they have big influence on the atmosphere. By releasing lot of ashes and small particles into the atmosphere, a layer of them is formed around the Earth. This layer had greater albedo, thus it is reflecting the sunlight instead of letting it go through. This causes rapid drop in the global temperatures, and as was the case in 1815, it resulted in a year without summer. If the volcanic eruption is very big and comes from a super-volcano, than it can have much longer impact, lasting for decades or even centuries.
Answer: Water pollution can have disastrous effects on the environment.
Explanation:
- Pollution in the water can reach a point where there isn't enough oxygen in the water for the fish to breathe. The fish can suffocate and not have enough air.
- Pollution affects the entire food chain. Small fishes absorb pollutants, such as chemicals, into their bodies. Bigger fishes eat the smaller fishes and get the pollutants as well. Birds or other animals may eat the bigger fishes and be harmed by the pollutants. One example of this was the use of the insecticide (bug killer) DDT, which is when birds of prey ate fishes that were infected with it, they would lay eggs with thin shells. The population of birds of prey began to drop until DDT was banished.
- Sewage causes major problems in rivers. Bacteria in the water will use oxygen to break down the sewage. If there is too much sewage, the bacteria could use up oxygen until there won't be enough left for the fish.
- Water pollution from major events like acid rain or oil spills can completely destroy marine habitats.
- One of the most important commodities for life on planet Earth is clean water. For over 1 billion people on the planet, clean water is nearly impossible to get. Dirty, polluted water can make them sick enough to die.
