What is the major cause of the greenhouse effect?

Question

responses

Carbon dioxide in the water

soot from coal plants in the water

soot from coal plants in the atmosphere

carbon dioxide in the atmosphere

Answer 1

The major cause of the greenhouse effect is carbon dioxide in the atmosphere. When certain gases, including carbon dioxide, are released into the atmosphere, they trap heat from the sun and prevent it from escaping back into space. This leads to an increase in global temperatures, which can have far-reaching effects on climate and ecosystems. While soot from coal plants may contribute to air pollution and have other negative environmental impacts, it is not the primary cause of the greenhouse effect.

Answer 2

Which is an effect of global warming?
responses

rising sea level over a period of time

increasing carbon dioxide in the atmosphere

changing seasons every year

increasing greenhouse gas concentration in air

Answer 3

One effect of global warming is the rising sea level over a period of time. As global temperatures increase, it causes the polar ice caps and glaciers to melt, which contributes to the rise in sea levels. This can result in coastal flooding, erosion, and the displacement of communities living in low-lying areas. Increasing carbon dioxide in the atmosphere and increasing greenhouse gas concentrations in the air are factors that contribute to global warming itself, rather than being direct effects of it. Changing seasons every year can be influenced by various natural processes but is not directly caused by global warming.

Answer 4

Which form of energy can be connected closely to climate change?
responses

hydroelectric

coal

wind

solar

Answer 5

The form of energy that can be connected closely to climate change is coal. Coal is a fossil fuel that, when burned for energy, releases large amounts of carbon dioxide and other greenhouse gases into the atmosphere. These greenhouse gas emissions contribute significantly to the increase in global temperatures and climate change. Hydroelectric, wind, and solar energy sources are considered cleaner alternatives as they have lower or negligible greenhouse gas emissions, and therefore have a much smaller impact on climate change.

Answer 6

Which choice would have the smallest impact on climate change when purchasing apples at the store?
responses

buying apples in large quantities to reduce trips to the store

buying apples that have no packaging

buying apples that are locally grown

buying apples from farms that plan to use organic practices

Answer 7

Buying apples that are locally grown would have the smallest impact on climate change when purchasing apples at the store. Locally grown apples require less transportation compared to apples that are shipped from distant locations, resulting in lower carbon emissions from transportation. Additionally, supporting local farmers reduces the carbon footprint associated with long-distance transportation and supports regional economies.

Answer 8

Which orders the activities from the greatest to least impact to reduce consumption of fossil fuels?
responses

walk to work, carpool to work, drive alone to work

carpool to work, walk to work, drive an electric car to work

drive an electric car to work, walk to work, carpool to work

drive alone to work, drive an electric car to work, carpool to work

Answer 9

The correct order from the greatest to least impact to reduce consumption of fossil fuels is:

1. Drive an electric car to work
2. Carpool to work
3. Walk to work

Driving an electric car to work has the greatest impact as it completely eliminates the use of fossil fuels, assuming the car is powered by renewable energy sources. Carpooling to work reduces the number of vehicles on the road, leading to a decrease in overall fuel consumption. Walking to work has the least impact on reducing consumption of fossil fuels as it does not involve any vehicle use.
