Test on Introduction to Environmental Science

Question 1: Deforestation causes animals to lose their natural habitats.

A. Ano

B. Ne

Explanation: The study materials explicitly list 'animals lose their habitas (homes)' as a consequence of deforestation.

Question 2: Deforestation is primarily caused by the damage to the ozone layer from freons and other chemicals.

A. Ano

B. Ne

Explanation: The study materials state that deforestation is caused by cutting down rainforests for wood, agriculture, ground for living, and for fields to grow palm oil trees or soya. The hole in the ozone layer, caused by freons and other chemicals, is listed as a separate ecological problem, not a cause of deforestation.

Question 3: According to the study materials, which of the following are described as causes of water pollution?

A. Factories and power plants discharging their waste into water systems

B. Chemicals found in household cleaning products

C. Exhaust gases from traffic and heavy industry

D. Used oil from households

Explanation: The study materials state under 'A. Pollution' that 'Ground and water: factories and power plants emit discharge their waste into water system' and 'Pollution from households: chemical in cleaing products, dont separate trash, to much rubish and plasties, used oil.' Exhaust gases from traffic cause air pollution (smog), not water pollution.

Question 4: According to the provided text, into which categories can pollution be divided?

A. Air pollution

B. Soil pollution

C. Water pollution

D. Noise pollution

Explanation: The study materials explicitly state: 'We can divide pollution into three categories: Air pollution, soil pollution, water pollution.' Noise pollution is not mentioned as one of these categories in the provided text.

Question 5: Deforestation is primarily caused by the need to create new areas for mining operations.

A. Ano

B. Ne

Explanation: The study materials state that deforestation occurs for wood, for agriculture, for land for housing, and for fields to grow palm trees or soybeans. Mining operations are not listed as a reason for deforestation.
