Earth's Climate and Energy Systems

This lesson explores Earth's changing climate, focusing on past climate changes during the Eocene and cryogenic periods. It examines how carbon dioxide and methane affect energy entering and exiting Earth's system, leading to temperature changes. The lesson includes a quiz on energy absorption and key concepts, and uses simulations to model historical climate conditions.

What is the main investigation question for this lesson?

• What is the history of Earth's climate changes?

• How do carbon dioxide and methane affect Earth's energy system?

• What are the effects of volcanic eruptions on climate?

• How does sunlight affect Earth's temperature?

What happens when more energy enters Earth's system than exits?

• The global temperature fluctuates randomly.

• The global temperature increases.

• The global temperature remains stable.

• The global temperature decreases.

During the Eocene period, what was a significant factor in the warming of Earth's climate?

• Increase in carbon dioxide and methane

• Decrease in sunlight

• Decrease in ocean temperatures

• Increase in volcanic activity

What is the Cryogenic period also known as?

• Snowball Earth

• The Jurassic Period

• The Eocene Epoch

• The Ice Age

What effect does increased ice coverage have on Earth's temperature?

• It has no effect on Earth's temperature.

• It causes Earth's temperature to fluctuate.

• It decreases Earth's temperature.

• It increases Earth's temperature.

What is the albedo effect?

• The absorption of sunlight by Earth's surface

• The warming of Earth's atmosphere

• The cooling of Earth's oceans

• The reflection of sunlight by ice and snow

In the simulation, what happens when carbon dioxide and methane levels are increased?

• The Earth's temperature increases.

• The Earth's temperature becomes unpredictable.

• The Earth's temperature remains the same.

• The Earth's temperature decreases.

What role does sulfur dioxide play in the simulation?

• It has no effect on Earth's energy system.

• It decreases the amount of energy entering Earth's system.

• It increases the amount of energy entering Earth's system.

• It increases the amount of energy exiting Earth's system.

What is a key concept learned from the simulation regarding energy balance?

• More energy entering than exiting cools the Earth.

• More energy exiting than entering warms the Earth.

• Equal energy entering and exiting maintains temperature stability.

• Energy balance has no effect on Earth's climate.

What is the significance of the Eocene and Cryogenic periods in climate studies?

• They show that Earth's climate has always been stable.

• They demonstrate the impact of human activity on climate.

• They provide examples of natural climate variability.

• They prove that climate change is a recent phenomenon.
