Climate Change & its Causes

What is climate change?

• Climate change is a result of natural cycles only

• Climate change is long-term changes in temperature, precipitation, and atmospheric conditions primarily caused by human activities.

• Climate change is a myth created by scientists

• Climate change is caused by aliens

Answer explanation

Climate change refers to long-term changes in temperature, precipitation, and atmospheric conditions primarily caused by human activities, not natural cycles, myths, or aliens.

What are greenhouse gases?

• Greenhouse gases are gases that trap heat in the Earth's atmosphere.

• Greenhouse gases are gases that cool the Earth's atmosphere.

• Greenhouse gases are gases that have no impact on the Earth's atmosphere.

• Greenhouse gases are gases that deplete the ozone layer.

Answer explanation

Greenhouse gases trap heat in the Earth's atmosphere, leading to the greenhouse effect.

How do greenhouse gases contribute to climate change?

• Greenhouse gases have no impact on climate change.

• Greenhouse gases cool the Earth's atmosphere, leading to a decrease in global temperatures.

• Greenhouse gases trap heat in the Earth's atmosphere, leading to an increase in global temperatures.

• Greenhouse gases only affect local weather patterns, not global climate.

Answer explanation

Greenhouse gases trap heat in the Earth's atmosphere, leading to an increase in global temperatures.

What are the main sources of greenhouse gas emissions?

• Reducing plastic waste

• Building more green spaces

• Burning fossil fuels, deforestation, agriculture, and industrial processes

• Using renewable energy sources

Answer explanation

The main sources of greenhouse gas emissions are burning fossil fuels, deforestation, agriculture, and industrial processes. These activities release significant amounts of greenhouse gases into the atmosphere.

What is the greenhouse effect?

• The greenhouse effect is the process by which the ozone layer protects the Earth from harmful UV rays.

• The greenhouse effect is the process by which the Earth's atmosphere cools down the planet's surface.

• The greenhouse effect is the process by which radiation from a planet's atmosphere warms the planet's surface to a temperature above what it would be without its atmosphere.

• The greenhouse effect is the process by which plants trap heat from the sun.

Answer explanation

The greenhouse effect is the process by which radiation from a planet's atmosphere warms the planet's surface to a temperature above what it would be without its atmosphere.

How does deforestation contribute to climate change?

• Deforestation reduces the number of trees that can absorb carbon dioxide, leading to increased greenhouse gas emissions.

• Deforestation leads to the creation of new forests, which help reduce greenhouse gas emissions.

• Deforestation increases the number of trees that can absorb carbon dioxide, reducing greenhouse gas emissions.

• Deforestation has no impact on climate change.

Answer explanation

Deforestation reduces the number of trees that can absorb carbon dioxide, leading to increased greenhouse gas emissions.

What role do fossil fuels play in climate change?

• Fossil fuels have no impact on climate change

• Fossil fuels contribute to climate change by releasing greenhouse gases when burned.

• Fossil fuels help mitigate climate change

• Fossil fuels reduce greenhouse gas emissions

Answer explanation

Fossil fuels contribute to climate change by releasing greenhouse gases when burned.

How does agriculture impact climate change?

• Agriculture impacts climate change through wind patterns, ocean currents, and volcanic eruptions.

• Agriculture impacts climate change through seismic activity, plate tectonics, and asteroid impacts.

• Agriculture impacts climate change through solar radiation, cloud cover, and precipitation levels.

• Agriculture impacts climate change through deforestation, methane emissions from livestock, and use of fertilizers that release greenhouse gases.

Answer explanation

The correct choice highlights how agriculture impacts climate change through deforestation, methane emissions from livestock, and use of fertilizers that release greenhouse gases.

What is the difference between weather and climate?

• Weather is short-term, climate is long-term.

• Weather only refers to temperature, while climate refers to all weather elements.

• Weather and climate are the same thing.

• Weather is short-term, climate is long-term.

Answer explanation

The correct answer is that weather is short-term, while climate is long-term.

How do human activities contribute to climate change?

• Human activities release oxygen which cools the atmosphere.

• Human activities reduce the amount of greenhouse gases in the atmosphere.

• Human activities release greenhouse gases like carbon dioxide and methane, which trap heat in the atmosphere and contribute to climate change.

• Human activities have no impact on climate change.

Answer explanation

Human activities release greenhouse gases like carbon dioxide and methane, which trap heat in the atmosphere and contribute to climate change.
