Earth's Atmosphere and Climate Simulation

In Lesson 3 of Earth's Changing Climate, students explore changes in the atmosphere using a climate simulation. The lesson involves conducting experiments with different gases to observe their effects on Earth's temperature, ice levels, and energy absorption. Key findings include the impact of carbon dioxide and methane on climate change. The lesson concludes with a discussion of these results and introduces the next steps in understanding climate data collected by scientists.

What is the main focus of Lesson 3 in Earth's changing climate series?

• Investigating changes to the Earth's core

• Exploring the Earth's changing climate simulation

• Analyzing ocean currents

• Studying the Earth's magnetic field

Which tool is used to explore changes in the Earth's atmosphere in this lesson?

• Volcano eruption simulator

• Weather forecasting model

• Ocean current simulator

• Earth's changing climate simulation

What does 'ppm' stand for in the context of atmospheric gases?

• Parts per million

• Particles per meter

• Pressure per molecule

• Pounds per meter

What is the initial setting for carbon dioxide in the simulation?

• 300 ppm

• 200 ppm

• 400 ppm

• 100 ppm

What happens to the Earth's surface when carbon dioxide levels are increased in the simulation?

• The surface cools down

• The surface glows more and temperature increases

• The surface freezes

• The surface remains unchanged

How does methane behave in the simulation compared to carbon dioxide?

• It behaves the same as carbon dioxide

• It has no effect on temperature

• It increases ice levels

• It decreases energy absorption

What is the effect of increasing sulfur dioxide in the simulation?

• Temperature and energy absorption increase

• Ice levels decrease

• Temperature and energy absorption decrease

• No change is observed

What was observed when nitrogen dioxide levels were changed in the simulation?

• Increase in energy absorption

• Significant temperature increase

• Significant temperature decrease

• No change in temperature or ice levels

What key concept was discovered regarding carbon dioxide and methane?

• They have no effect on Earth's climate

• They only affect ice levels

• Their changes affect the amount of energy absorbed by the surface

• Their changes do not affect energy absorption

What will be explored in the next lesson following this one?

• The role of the sun in climate change

• Data from scientists on atmospheric gases

• The impact of volcanic eruptions

• The effects of ocean currents
