B) Around 300 million years ago, the regions where coal formed were located in tropical climates that were partially submerged on the coasts
Explanation:
The distribution of the world's major coal reserves supports the the theory of plate tectonics because the regions where they formed were in tropical climates around 300 million years ago.
Coal is a fossil fuel used to produce energy when burnt.
They are formed in tropical swamps where there is luxuriant plants life.
To form a coal, a terrain such as swamp must have rich plant life. The plant is rapidly buried and cut off from the oxic environment. Further burial under heat and pressure transforms the plant matter into coal.
- The major reserves of coal in the world today is found in Europe and North America
- These are temperate regions whose conditions do not favor the formation of coal.
- Those regions must have moved from around the equator to their present day position.
- The coal formed when they were much closer to the equator around 300 million years ago.

False
“The color of a mineral's streak is NOT always the same (as the) color of the mineral sample.”
Answer:
Chemical Fertilizers
C. Algal blooms followed by eutrophication is the correct one
Stockyard Runoff
Correct D. Increased biological oxygen demand/decreased dissolved oxygen
Soil disturbance
Correct A. Erosion, flooding; clogged shipping channels and harbors
Pesticides
Correct B. Reproductive failure, poisoning, and/or death (pollinators, pets, livestock, predators, children)
Explanation:
For industrial agriculture to be effective and productive today, we have to take into account many factors so our practices function in a good way. When it comes to chemical fertilizers, it is NOT a risk the Increased biological oxygen demand/decreased dissolved oxygen
, the correct risk is algal blooms followed by eutrophication. Regarding Stockyard Runoff it is wrong to think the algal blooms followed by eutrophication as risk, the actual risk is the increased biological oxygen demand/decreased dissolved oxygen. The risk in soil disturbance
is the erosion, flooding; clogged shipping channels and harbors and thinking about pesticides
, they are in risk for reproductive failure, poisoning, and/or death (pollinators, pets, livestock, predators, children)
.
