Answer:
There is a big public park near a manufacturing factory that emits harmful gases, where his children can play.
Explanation:
It's pretty self explanatory. Harmful gases are harmful. The children are in serious danger by playing in that park and inhaling these gases from the factory.
The correct answers are:
- Polar ice caps would melt, increasing sea levels;
Because of the rise of the temperatures, the permafrost, glaciers, and polar ice caps would mostly melt. As they melt, they will increase the sea levels significantly because they will introduce much more water into the the seas and oceans.
- Wildlife would have to migrate or die;
With increasing sea levels, as well as change of habitats, lot of animals would find themselves in situation where they will have to migrate, because if they don't, they will find themselves in water and drown, or starve to death.
- Hurricanes and typhoons could increase in intensity;
Because the water in the sea levels will increase, and the water bodies will become even bigger, the hurricanes and typhoons will be able to become stronger and more intense, thus be more destructive as well.
Answer:
Catastrophism.
Explanation:
According to Geology, there's a theory which held that surface, mountains, lakes, were created by suddenly because of great catastrophes like earthquakes and floods.
I believe that the perpendicular equation would be the opposite sign and the reciprocal of the original slope. Then you just plug in the x and y coordinate to y=mx+b and solve for b.
y=4x+b
3=4(-4)+b
3=-16+b
b=19
y=4x+19
