Unit 2 Test Review

Front

What is the Natural Greenhouse Effect?

Back

The Natural Greenhouse Effect is the process by which certain gases in Earth's atmosphere trap heat, keeping the planet warm enough to support life.

Front

What is the Human Enhanced Greenhouse Effect?

Back

The Human Enhanced Greenhouse Effect refers to the increase in greenhouse gases in the atmosphere due to human activities, such as burning fossil fuels and deforestation, leading to more heat being trapped and global warming.

Front

What are the main agricultural practices that contribute to greenhouse gas emissions?

Back

Agricultural practices such as rice production and raising livestock contribute to greenhouse gas emissions, raising Earth's temperatures.

Front

How does land change for agricultural use impact greenhouse gas emissions?

Back

Land change for agricultural use, such as deforestation and converting natural habitats into farmland, contributes to greenhouse gas emissions, raising Earth's temperatures.

Front

What is the impact of volcanic activity on Earth's climate?

Back

Volcanic activity has very little impact on Global Climate Change; in fact, volcanoes release less than a percent of the carbon dioxide released by human activities.

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 role do livestock play in climate change?

Back

Livestock contribute to climate change by producing methane, a potent greenhouse gas, during digestion and through manure management.

Front

What is the significance of carbon dioxide in climate change?

Back

Carbon dioxide is a major greenhouse gas that contributes to global warming; it is released through human activities like burning fossil fuels and deforestation.

Front

What is the difference between natural and human-induced climate change?

Back

Natural climate change occurs due to natural processes, while human-induced climate change is caused by human activities that increase greenhouse gas concentrations in the atmosphere.

Front

What are some effects of climate change on agriculture?

Back

Climate change can lead to altered weather patterns, affecting crop yields, increasing pests and diseases, and impacting food security.
