Unit 6 (Human Impact) Grade Recovery

Front

What is climate change?

Back

Climate change refers to significant changes in global temperatures and weather patterns over time, primarily caused by human activities such as burning fossil fuels.

Front

What are greenhouse gases?

Back

Greenhouse gases are gases in Earth's atmosphere that trap heat, including carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O).

Front

What is the greenhouse effect?

Back

The greenhouse effect is the warming of a planet due to trapped radiation, which occurs when greenhouse gases absorb and reradiate infrared radiation.

Front

What are non-renewable resources?

Back

Non-renewable resources are natural resources that cannot be replenished as quickly as they are consumed, such as fossil fuels and minerals.

Front

What is an ecological footprint?

Back

An ecological footprint measures the environmental impact of an individual or community, including the amount of land and resources required to support their lifestyle.

Front

What is the impact of deforestation on climate change?

Back

Deforestation contributes to climate change by reducing the number of trees that can absorb CO2, leading to higher levels of greenhouse gases in the atmosphere.

Front

What are the effects of melting polar ice caps?

Back

Melting polar ice caps contribute to rising sea levels, which can lead to coastal flooding and loss of habitat for polar species.

Front

What is the role of carbon dioxide in the atmosphere?

Back

Carbon dioxide plays a crucial role in the atmosphere as a greenhouse gas, helping to regulate Earth's temperature by trapping heat.

Front

What is waste production's impact on the environment?

Back

Waste production can lead to pollution, habitat destruction, and increased greenhouse gas emissions, contributing to climate change.

Front

What is renewable energy?

Back

Renewable energy comes from sources that can be replenished naturally, such as solar, wind, and hydroelectric power.
