Exploring Our Universe and Climate Change

What is the Big Bang Theory?

• A theory that explains the formation of galaxies

• A theory that describes the origin of the universe

• A theory about the water cycle

• A theory about climate change

Which of the following is evidence supporting the Big Bang Theory?

• The presence of water on Earth

• The redshift of galaxies

• The greenhouse effect

• The water cycle

What is the redshift in the context of the Doppler effect?

• A shift towards shorter wavelengths

• A shift towards longer wavelengths

• A shift in temperature

• A shift in sound frequency

How do galaxies form according to current scientific understanding?

• Through the accretion of water

• Through the differentiation of elements

• Through the gravitational collapse of matter

• Through the greenhouse effect

What is accretion in space?

• The process of water evaporating

• The gradual accumulation of particles into a massive object

• The differentiation of Earth's layers

• The melting of polar ice caps

Which of the following gases is considered a major greenhouse gas?

• Oxygen

• Nitrogen

• Carbon dioxide

• Helium

What is the primary cause of rising sea levels?

• Increased volcanic activity

• Melting of ice caps and glaciers

• Increased rainfall

• Decreased evaporation

Which process is NOT part of the water cycle?

• Evaporation

• Condensation

• Photosynthesis

• Precipitation

What is the main driver of climate change?

• Natural disasters

• Human activities increasing greenhouse gases

• The water cycle

• The Big Bang Theory

Which of the following is a consequence of climate change?

• Decreased global temperatures

• Increased biodiversity

• More frequent extreme weather events

• Stabilised sea levels
