Show Answer Key & Explanations
Step-by-step solution for: 740 Environment English ESL worksheets pdf & doc
Let’s go through each question one by one and find the correct answer. I’ll explain simply so it’s easy to understand.
---
1. What do you call the area that is affected by pollution?
→ Pollution affects the environment — that’s the air, water, land, and living things around us.
✔ Answer: c) Environment
---
2. Which of these is a renewable energy source?
→ Renewable means it won’t run out. Wind keeps blowing! Coal, oil, and gas are fossil fuels — they take millions of years to form and will run out.
✔ Answer: b) Wind power
---
3. What happens when Earth’s temperature increases?
→ When Earth gets hotter, ice melts → sea levels rise. Also, weather gets wilder (extreme effects). But “increase in temperature” itself is called global warming. The best fit here is the effect on nature.
Wait — let’s check options again:
a) Increase in temperature → that’s the cause, not what happens *because* of it.
b) Environmental effect → too vague.
c) Global warming → this IS the increase in temperature.
d) Climate change → broader term, includes long-term changes.
Actually, if temperature increases, we say “global warming” is happening.
✔ Answer: c) Global warming
*(Note: Sometimes people mix up global warming and climate change — but for this level, global warming = rising temps)*
---
4. What does recycling mean?
→ Recycling = turning old stuff into new things. Like making paper from old newspapers.
✔ Answer: b) Turning waste into something useful
---
5. Which type of energy comes from moving water?
→ Moving water = hydroelectric power. Dams use rivers to make electricity.
✔ Answer: c) Hydroelectric
---
6. What kind of plant can clean polluted soil?
→ Some plants absorb toxins — called phytoremediation. Sunflowers are known for this!
✔ Answer: d) Sunflower
---
7. Alternative energies include:
→ Alternatives to coal/oil/gas = solar, wind, geothermal, etc. Fossil fuels are NOT alternative.
Options:
a) Solar energy ✔
b) Natural gas ✘ (fossil fuel)
c) Nuclear energy ⚠️ (some consider it alternative, but not renewable)
d) Both a and c → Hmm… nuclear isn’t always grouped with renewables. But in some curricula, it’s included as low-carbon. Let’s see context.
Looking at Q9 later — they list nuclear separately. Probably safest to pick only solar. Wait — option d says “both a and c”. If the test considers nuclear as alternative, then yes. But strictly speaking, alternative energy usually means renewable.
Check Q9: “Which is NOT renewable?” → lists nuclear as non-renewable. So probably not counted as alternative here.
But wait — Q7 says “alternative energies include” — and solar definitely is. Nuclear is debatable.
Look at answer choices — maybe they expect both? Actually, many textbooks include nuclear under “alternative” because it doesn’t burn fossil fuels.
I think for this level, they might accept d) Both a and c
✔ Final choice: d) Both a and c
---
8. Which part of your body is responsible for breathing?
→ Lungs! They take in oxygen and release carbon dioxide.
✔ Answer: c) Lungs
---
9. Which of the following is NOT a renewable resource?
→ Renewable = replenished naturally in short time.
a) Water cycle → yes, renewable
b) Solar energy → yes
c) Wind energy → yes
d) Nuclear energy → NO! Uranium is finite. Takes millions of years to form. Not renewable.
✔ Answer: d) Nuclear energy
---
10. What helps reduce greenhouse gases?
→ Greenhouse gases trap heat. Trees absorb CO₂ → planting trees helps! Burning trash or using more cars makes it worse.
✔ Answer: a) Planting trees
---
11. What is the most used natural resource worldwide?
→ Water! We drink it, grow food with it, make products with it. Even though air is everywhere, water is the most *used* resource.
✔ Answer: a) Water
---
12. Which animal is endangered due to habitat loss?
→ Polar bears lose ice homes. Tigers lose forests. Pandas lose bamboo forests. All three are endangered. Option d says “All of the above” — which matches.
✔ Answer: d) All of the above
---
13. What type of shopping bag is eco-friendly?
→ Reusable bags! Cloth or canvas bags you use over and over. Plastic bags pollute. Paper uses trees. Metal is heavy. Best is reusable cloth.
✔ Answer: c) Reusable cloth bag
---
14. What causes acid rain?
→ Acid rain comes from sulfur dioxide and nitrogen oxides — mostly from burning coal and oil in factories and cars.
✔ Answer: b) Air pollution from factories and vehicles
---
15. What are layers of the atmosphere?
→ From bottom to top: Troposphere, Stratosphere, Mesosphere, Thermosphere, Exosphere.
Option b lists them correctly.
✔ Answer: b) Troposphere, stratosphere, mesosphere, thermosphere, exosphere
---
16. Loss of biodiversity means:
→ Biodiversity = variety of life. Losing species = extinction.
✔ Answer: a) Extinction of species
---
17. Which of the following is biodegradable?
→ Biodegradable = breaks down naturally. Banana peel rots. Plastic bottle doesn’t. Glass jar doesn’t. Aluminum can takes centuries.
✔ Answer: c) Banana peel
---
18. Carbon dioxide contributes to:
→ CO₂ traps heat → causes global warming → leads to climate change.
✔ Answer: a) Global warming
---
19. Which of the following can be recycled?
→ Paper, glass, metal cans — all recyclable. Food scraps compost, not recycle.
✔ Answer: d) All of the above *(assuming “above” refers to paper, glass, metal — even though listed as separate items)*
Wait — looking back:
Question 19: “Which of the following can be recycled?”
Options:
a) Milk cartons ✔ (often recyclable)
b) Batteries ✘ (special disposal, not regular recycling)
c) Light bulbs ✘ (contain mercury, special handling)
d) Both a and b → no, batteries not typically recycled curbside.
Hmm… tricky. In many places, milk cartons ARE recyclable. Batteries and light bulbs need special centers.
So likely only a) is correct? But option d says “both a and b” — which would be wrong.
Wait — maybe the question assumes standard curbside recycling. Then only milk cartons.
But let’s check real-world:
- Milk cartons: YES (in many areas)
- Batteries: NO (hazardous)
- Light bulbs: NO (mercury)
So only a) should be right. But there’s no “only a” option? Wait — look again:
The options are:
a) Milk cartons
b) Batteries
c) Light bulbs
d) Both a and b
If only a is correct, but d includes b (wrong), then none match? That can’t be.
Perhaps in their curriculum, they teach that batteries CAN be recycled (which is true — just not in regular bins).
Maybe the intended answer is d) Both a and b, assuming students know batteries go to special recycling.
Alternatively, perhaps I misread — let me double-check the image description.
Since I don’t have the exact text, I’ll assume based on common teaching:
Many schools teach that batteries and electronics can be recycled — just differently.
To avoid confusion, let’s pick a) Milk cartons as safest.
But since d says “both a and b”, and if b is incorrect, then d is wrong.
Wait — actually, in multiple-choice tests, sometimes “all of the above” or combinations are traps.
Given that, and since milk cartons are clearly recyclable, and others aren’t in normal bins, I’ll go with a).
But the options don’t allow selecting only a unless it’s listed alone — which it is.
Yes — option a is “Milk cartons” — that’s valid.
✔ Answer: a) Milk cartons
*(Note: If the test expects broader definition, it might differ — but based on standard knowledge, milk cartons are commonly accepted as recyclable while batteries require special processes.)*

20. Which is the following is a non-renewable resource?
→ Non-renewable = runs out. Timber? Trees grow back — renewable. Copper? Mined from earth — finite. Solar? Infinite. Freshwater? Renewed by cycle — generally considered renewable.
Copper is a mineral — once mined, gone forever (on human timescale).
✔ Answer: b) Copper
