Sand dunes.

Question

Sand dunes protect beaches against erosion and flooding due to storms.

Which human activity would have the most negative impact on dune grasses and the coast?

building houses near the beach
walking on the dunes of the beach
allowing kids to play on the beach

Answer 1

Building houses near the beach would have the most negative impact on dune grasses and the coast. This activity can lead to habitat destruction, increased runoff and pollution, and greater vulnerability to erosion, as the natural buffer provided by the dunes is compromised. In contrast, while walking on the dunes and allowing kids to play on the beach can cause some disturbance, these activities are typically less impactful than the extensive alteration of the coastal landscape that comes with construction.

Answer 2

Oil is a fossil fuel used to run cars, heat up homes, and produce electricity. Oil can be removed from the bottom of the ocean through drilling. Drilling machines dig deep down into the Earth. When oil is found, pipes carry it to the surface. Sometimes, accidents happen that cause the oil to spill into the oceans. The oil can not only kill marine organisms, but when it reaches the surface of the water, some chemicals evaporate, become part of the atmosphere, and pollute the air.

Based on the passage, which resources and organisms are affected by oil spills? Select three options.

air
land
water
birds in the air
trees on land
organisms in water

Answer 3

Based on the passage, the resources and organisms affected by oil spills are:

1. Air
2. Water
3. Organisms in water

These options are directly mentioned in the passage as being impacted by oil spills.

Answer 4

A carbon footprint is a measure of the amount of carbon human activities, like using energy, release into the atmosphere. Refer to the chart illustrating common household activities and their corresponding energy usage.

Based on this data, which is the most impactful approach to reducing the highest carbon-emitting household activity?

limiting time watering plants
wearing layers of clothing
turning off lights when leaving a room
unplugging electronics when not in use

Answer 5

To determine the most impactful approach to reducing the highest carbon-emitting household activity, we would need to know which specific household activity has the highest carbon emissions from the chart you referenced. However, generally speaking, the activity that typically contributes the most to a household's carbon footprint is often related to energy consumption for heating or electricity use.

If we assume common high-emission activities include heating and electricity usage, the most impactful approach from the options provided would likely be:

Turning off lights when leaving a room.

This action directly reduces electricity consumption, which can significantly lower carbon emissions associated with energy production. Unplugging electronics when not in use can also be effective but may have a smaller overall impact compared to consistently managing lighting in a household.

Please refer to the specific data in your chart to confirm which activity has the highest emissions, as that will provide the most accurate way to assess the most effective reduction strategy.

Answer 6

choose another

Answer 7

If we are considering other impactful approaches aside from turning off lights when leaving a room, unplugging electronics when not in use would be a good choice as well. Electronics can consume energy even when they're not actively in use (known as "phantom" or "vampire" energy), so unplugging them can help reduce overall energy consumption and, consequently, the carbon footprint associated with electricity usage.

So, to summarize, after turning off lights, unplugging electronics when not in use would be a strong approach to reducing carbon emissions related to household energy usage.

Answer 8

wearing layers of clothing

A 3 column by 5 row table. Column 1 is titled Activity with the following entries: use of materials in production, release of carbon in production, energy use in production, water use in production, litter in oceans. Column 2 is titled Plastic with the following entries: +++, ++, ++, +, +++++. Column 3 is titled Paper with the following entries: +++++, +++++, +++++, +++, +.
Gina’s community is considering whether it should ban the use of plastic bags. Help her analyze the costs and benefits of using plastic and paper bags by completing the paragraph.

Based on the data presented,
bags have less impact on Earth’s resources. Even though
bags have less impact on organisms in the oceans, the production of
bags uses more of Earth’s materials and releases more carbon into the atmosphere.

Answer 9

Based on the data presented, paper bags have less impact on Earth’s resources. Even though plastic bags have less impact on organisms in the oceans, the production of paper bags uses more of Earth’s materials and releases more carbon into the atmosphere.

Answer 10

whats the first two?? the third is correct

Answer 11

I apologize for the mistake. Based on the data presented, plastic bags have less impact on Earth’s resources. Even though plastic bags have less impact on organisms in the oceans, the production of paper bags uses more of Earth’s materials and releases more carbon into the atmosphere.
