1. Which is a sustainable practice?

Question

operating wind farms
clear cutting
flood irrigation
overfishing

2. Why are invasive species dangerous to the environment?
They pollute the environment.
They are all voracious predators.
They threaten biodiversity.
They are nonrenewable.

3. Freshwater can be renewed, but environmentalists consider it nonrenewable. Why is there a contradiction in classification?
Freshwater is recycled through the use of irrigation, bathing, and everyday use.
Freshwater is easily polluted or depleted before it can be replaced.
Freshwater evaporates and condenses, and then precipitation returns it to the lakes.
Freshwater is highly affected by global warming, and is quickly evaporating.

5. Which results from an increase in the greenhouse effect?
continental shifts
wildfires
volcanic eruptions
global warming

6. Which of the following substitutions can help reduce air pollution?
using a bike instead of a car
using dumps instead of landfills
using coal instead of oil
using fireplaces instead of a wind farms

7. Which water source may become polluted as it travels over land?
ponds
groundwater
oceans
runoff

8. Which type of pollution includes CFCs and smog?

land air water or volcanic

9. Which is a consequence of global warming?
cooling oceans
growing glaciers
less frequent hurricanes
rising sea levels

10. A new highly nutritious crop is going to be planted in an area where it has never been planted before. Which is the most likely outcome of such an event?
positive as it malnourishes the local population
positive as it changes local biodiversity
negative as it threatens local biodiversity
negative as it malnourishes the local population

Use the drop-down menus to identify how energy is transformed.

Someone claps his or her hands.

A solar panel is used to power a house.

Answer 3

Here are the energy transformations for each scenario:

1. Someone claps his or her hands.

   • Kinetic energy → Sound energy

2. A solar panel is used to power a house.

   • Solar energy → Electrical energy

Let me know if you need any more assistance!

Answer 4

for A solar panel is used to power a house. the options could be Motion energy to potential energy and
Radiant energy to electrical energy

for Someone claps his or her hands it can be Motion energy to sound energy or
Motion energy to radiant energy

Answer 5

Thank you for providing the options! Here’s the correct energy transformation for each scenario based on the options you mentioned:

1. Someone claps his or her hands.

   • Motion energy to sound energy

2. A solar panel is used to power a house.

   • Radiant energy to electrical energy

These transformations accurately describe the processes occurring in both scenarios. If you have any more questions or need further clarification, feel free to ask!

Answer 6

Renewable resources include wind energy, solar energy, wood, and plant materials. Which statement best describes renewable resources?

man-made materials that replenish over time
natural resources that replenish themselves over time
natural resources that have a limited supply
man-made materials that have a limited supply

Answer 7

The statement that best describes renewable resources is:

natural resources that replenish themselves over time.

Renewable resources are naturally occurring materials that can be replenished naturally at a rate that allows for sustainable use. If you have any other questions or need further assistance, feel free to ask!

Answer 8

Which statements describe advantages of using renewable resources? Check all that apply.

lower environmental impact
lower cost of production
replenish faster than they are used
more reliable than other resources
produce cleaner energy

Answer 9

The statements that describe advantages of using renewable resources include:

1. lower environmental impact
2. replenish faster than they are used
3. produce cleaner energy

While "lower cost of production" and "more reliable than other resources" may be true in some contexts, they can vary based on specific circumstances, technologies, and locations. Therefore, the three listed above are more universally recognized advantages of renewable resources. If you have more questions or need further clarification, feel free to ask!

Answer 10

Which words or phrases describe some advantages of nonrenewable resources? Check all that apply.

easy to produce
habit-forming
finite
affordable
abundant

Answer 11

The words or phrases that describe some advantages of nonrenewable resources include:

1. easy to produce
2. affordable
3. abundant

While "finite" refers to the limited supply of nonrenewable resources, it does not represent an advantage. "Habit-forming" is not typically used to describe the advantages of nonrenewable resources in the context of energy or materials.
