Pre-test on Climate Change

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

How do human activities contribute to climate change?

Back

Human activities, such as burning fossil fuels and deforestation, increase the concentration of greenhouse gases in the atmosphere, leading to climate change.

Front

What is the greenhouse effect?

Back

The greenhouse effect is the warming of Earth's surface due to the trapping of heat by greenhouse gases in the atmosphere.

Front

What is climate change?

Back

Climate change refers to long-term changes in temperature, precipitation, and other atmospheric conditions on Earth.

Front

What is the relationship between carbon dioxide levels and global temperatures?

Back

Higher carbon dioxide levels lead to increased heat retention in the atmosphere, resulting in higher global temperatures.

Front

What role do work-saving technologies play in climate change?

Back

Work-saving technologies often rely on fossil fuels, which release greenhouse gases like carbon dioxide and methane when used.

Front

What is the significance of the year 1960 in climate data?

Back

The year 1960 marks a significant increase in atmospheric carbon dioxide levels, which have been steadily rising since then.

Front

How can we measure changes in climate over time?

Back

Changes in climate can be measured using historical temperature records, ice core samples, and atmospheric gas concentrations.

Front

What are some effects of climate change on the environment?

Back

Effects of climate change include rising sea levels, increased frequency of extreme weather events, and shifts in ecosystems.

Front

What is the role of carbon sinks in climate change?

Back

Carbon sinks, such as forests and oceans, absorb carbon dioxide from the atmosphere, helping to mitigate climate change.
