Exploring Climate Change's Impact on Earth's Atmosphere

What are Milankovitch cycles?

• Patterns of climate change due to variations in Earth's tilt and orbit

• Changes in ocean currents

• Fluctuations in solar radiation

• Volcanic activity cycles

Which of the following is NOT a method used by scientists to study past climates?

• Satellite imagery

• Ice core samples

What epoch are we currently living in?

• Pleistocene

• Holocene

• Miocene

• Eocene

How did the stable temperatures of the Holocene impact human development?

• Caused mass migrations

• Led to the extinction of many species

• Increased volcanic activity

• Enabled the development of agriculture

What major event marked a sharp increase in human impact on the global climate?

What is the primary cause of the rise in average temperatures in the early 20th century?

• Deforestation

• Increased volcanic activity

• Carbon dioxide emissions from fossil fuels

• Changes in Earth's orbit

What is the greenhouse effect?

• The reflection of sunlight by ice sheets

• The absorption of heat by oceans

• The trapping of heat by greenhouse gases in the atmosphere

• The cooling effect of volcanic ash

What is a potential consequence of global warming on sea levels?

• Sea levels will rise

• Sea levels will remain the same

• Sea levels will fluctuate randomly

• Sea levels will decrease

Which habitats are especially threatened by global warming?

• Tundras

• Grasslands

• Coral reefs

• Deserts

What is needed to combat global warming effectively?

• More deforestation

• Ignoring the problem

• Global commitment to conserve energy and develop sustainable sources

• Increased fossil fuel usage
