Which environmental concern is most associated with burning fossil?
When fossil fuels are burned, they release nitrogen oxides into the atmosphere, which contribute to the formation of smog and acid rain. The most common nitrogen-related compounds emitted into the air by human activities are collectively referred to as nitrogen oxides.
Which of the following would cause the greatest decrease in the number of species of plants and animals living in some of the lakes & streams?
Which of the following would cause the greatest decrease in the number of species of plants and animals living in some of the lakes & streams? reduce the use of nonrenewable resources.
What has been the greatest effect on natural selection through the use of pesticides on certain insect populations?
What has been the greatest effect of natural selection through the use of pesticides on certain insect populations? Natural selection has been altered because the insects and their predators are killed. The rate of selection is increased because the pesticides do not kill the insects that are naturally resistant to it.
What is a major drawback of using fossil fuels?
Pollution is a major disadvantage of fossil fuels. This is because they give off carbon dioxide when burned thereby causing a greenhouse effect. This is also the main contributory factor to the global warming experienced by the earth today.
Are all lakes connected to rivers?
Most lakes have at least one natural outflow in the form of a river or stream, which maintain a lake’s average level by allowing the drainage of excess water. Some lakes do not have a natural outflow and lose water solely by evaporation or underground seepage or both. They are termed endorheic lakes.
What will most likely happen if the human population continues to grow at a current rate?
What will most likely happen if the human population continues to grow at current rates? There will be fewer natural resources available for future generations. There will be fewer natural resources available for future generations. There will be an increase in nitrogen levels in the atmosphere.
Which of the following is a result of disruptive selection?
Individuals with extreme phenotypes have a higher fitness. Individuals with extreme phenotypes have a higher fitness. (Individuals with extreme phenotypes have a higher fitness is a result of disruptive selection. Disruptive selection eliminates phenotypes near the average value and favors extreme phenotypes.
What will most likely happen if the human population continues to grow at current rates?
Why can’t we depend on fossil fuels forever?
Fossil fuels are a nonrenewable resource Even if fossil fuels didn’t pollute and contribute to global warming, we won’t be able to rely on them forever. This is because fossil fuels are nonrenewable, meaning they don’t naturally replenish fast enough for humans to use forever.
Which fuel is not a fossil fuel?
Complete answer: ‘Wood’ is not a fossil fuel. – Fossil fuels consist of carbon in a very large amount. They include petroleum, coal, and natural gas.
What are the similarities and differences among a lake and river?
Comparison Chart
| Lake | River |
|---|---|
| Immobile body of water | Flowing body of water |
| Looks like a huge pond | Looks like a snake |
| Inland, does not communicate with other water bodies | Moves along its water banks and communicates with other water bodies |
| A freshwater source | A freshwater source |
Why do lakes not dry up?
So why don’t lakes just dry up? Some do. For a lake to keep its water over time, it has to be replenished. So these sorts of lakes may also get underground water that flows in from underneath the lake – the lake floor may be an area of water input, rather than a drain for the lake.
What happens if the population increases?
The human population is predicted to reach around 10 billion by 2050. As the population increases, the yield of food from farming will also have to increase or malnutrition and starvation will occur.
What will happen if there is overpopulation?
There are some benefits of overpopulation, more people means more labor force, it can product more things, and more people will buy the products, However, the growth of population should be similar to the food supply, so overpopulation will cause lack of food, and as the rate of growth of population exceeds the rate of …
