Let's go through each question on the worksheet and solve them step by step, providing explanations for each answer.

Question 1: True/False [2]

Statement: Three reasons for the deforestation of natural rainforests are mining, farming and logging.
✔ Answer: TRUE

Explanation:
Deforestation occurs due to human activities such as:
- Mining: Extracting minerals and resources often requires clearing large areas of forest.
- Farming: Land is cleared to grow crops or raise livestock (especially in tropical regions).
- Logging: Trees are cut down for timber and paper products.

These are all major causes of rainforest destruction globally.

Question 2: True/False [2]

Statement: The world's largest hot desert is the Sahara Desert in North America.
✘ Answer: FALSE

Explanation:
The Sahara Desert is indeed the largest hot desert in the world, but it is located in Africa, not North America. It spans across countries like Algeria, Egypt, Libya, Mali, and others in northern Africa.

So, the statement is false because of the incorrect location.

Question 3: True/False [2]

Statement: Population density and population distribution are the same thing.
✘ Answer: FALSE

Explanation:
- Population density refers to the number of people per unit area (e.g., people per square kilometer). It’s a measure of how crowded an area is.
- Population distribution refers to how people are spread out across a region — where they live (urban vs rural, coastal vs mountainous, etc.).

They are related concepts but not the same. One measures concentration; the other describes pattern.

Question 4: True/False [2]

Statement: Temperature is what everyone needs to live and to grow food.
✘ Answer: FALSE

Explanation:
While temperature is important for life and agriculture, it is not the only factor needed. People also need:
- Water
- Food
- Shelter
- Clean air
- Soil fertility

For growing food, factors like sunlight, water, soil quality, and nutrients are equally essential. So, saying temperature is *what everyone needs* is too narrow and misleading.

Question 5: True/False [2]

Statement: Many people in rural areas work in offices in the city centre.
✔ Answer: TRUE

Explanation:
Many people who live in rural areas commute to cities for work, especially in office jobs, healthcare, education, or government roles. This is common in many countries with urban centers that offer more employment opportunities.

So, while not all rural residents do this, it's accurate to say many do.

---

Question 6: True/False [2]

Statement: Rural areas have many services and supermarkets.
✘ Answer: FALSE

Explanation:
Rural areas typically have fewer services and limited access to large supermarkets compared to urban areas. They may have small local shops, but not the wide range of services (like hospitals, banks, schools, or big retail chains) found in cities.

So, this statement is generally false.

Question 7: Multiple Choice [4]

Question: Deforestation adds to global warming because …

Options:
A) there is no longer evaporation into the air which means the air doesn't cool.
B) we burn more fires from firewood made from those trees.
C) photosynthesis cannot occur.
D) the trees cannot scrub carbon dioxide from the air which causes a layer of gases to be trapped in the atmosphere.

✔ Correct Answer: D

Explanation:
Trees absorb carbon dioxide (CO₂) during photosynthesis, helping to reduce greenhouse gases in the atmosphere. When forests are cut down:
- Trees are removed → less CO₂ absorption.
- Often, the trees are burned or left to rot → releasing stored CO₂ back into the air.
- This increases the concentration of greenhouse gases, contributing to global warming.

Option D correctly explains this process: "the trees cannot scrub carbon dioxide from the air which causes a layer of gases to be trapped in the atmosphere."

While options B and C have some truth, D is the most comprehensive and scientifically accurate explanation in the context of climate change.

✔ Final Answers Summary:

| Question | Answer | Explanation |
|--------|--------|-----------|
| 1 | TRUE | Mining, farming, and logging are major causes of deforestation. |
| 2 | FALSE | The Sahara is in Africa, not North America. |
| 3 | FALSE | Density ≠ Distribution; different concepts. |
| 4 | FALSE | Temperature is important but not the only requirement for life or food. |
| 5 | TRUE | Many rural residents commute to urban offices. |
| 6 | FALSE | Rural areas usually lack extensive services and supermarkets. |
| 7 | D | Trees remove CO₂; without them, more CO₂ builds up, causing warming. |
