Accepted Answer

### Question 7
# Brief Explanations:
Greenhouse gas changes affect the overall climate system, which influences temperature and weather patterns across all seasons. So changes in greenhouse gases impact summer, winter, spring, and other seasons.
# Answer:
D. All seasons

### Question 8
# Brief Explanations:
Methane is primarily emitted from livestock (like cows during digestion) and landfills (where organic matter decomposes). Ice caps, oceans, and clouds are not main sources of methane release.
# Answer:
B. Livestock and landfills

### Question 9
# Brief Explanations:
Trapped heat in the atmosphere (due to greenhouse gases) leads to an increase in Earth's temperature, as the heat is retained and not radiated out into space.
# Answer:
C. Increase

### Question 10
# Brief Explanations:
Greenhouse gases such as carbon dioxide, methane, and water vapor are present in Earth's atmosphere, where they trap heat. The core, mantle, and crust are parts of Earth's interior and do not contain greenhouse gases in significant amounts.
# Answer:
D. Atmosphere

### Question 11
# Brief Explanations:
A colder Earth would lead to extreme cold conditions, as lower temperatures would result in more freezing weather, potential expansion of ice, and harsher cold - related phenomena. Fewer storms, no snow, and more sunlight are not typical results of a colder Earth.
# Answer:
B. Extreme cold conditions

### Question 12
# Brief Explanations:
Greenhouse gases trap heat, which directly affects Earth's temperature. Wind speed is related to air pressure differences, Earth's rotation is a planetary motion, and gravity is a fundamental force - none of these are mainly affected by greenhouse gases.
# Answer:
B. Earth’s temperature

### Question 13
# Brief Explanations:
Respiration (by plants and animals) is a natural process that releases $CO_2$. Cars, factories, and power plants are human - made sources of $CO_2$ emissions.
# Answer:
C. Respiration

### Question 14
# Brief Explanations:
The greenhouse effect is a natural process where certain gases in the atmosphere trap heat, helping to keep Earth warm enough to support life. It is not entirely harmful (some level is necessary), not entirely human - made (occurs naturally), and not a weather event (it's a long - term climatic process).
# Answer:
C. A natural process

### Question 15
# Brief Explanations:
Winter storms form due to atmospheric conditions such as temperature, humidity, and air pressure systems. Earth's core, ocean salinity alone, and moon phases do not have a direct role in the formation of winter storms.
# Answer:
A. Atmospheric conditions
