weather and climate change

Multiple Choice

Why is understanding energy flow important for studying climate change?

• Because it helps us predict weather patterns

• Because it explains how energy is transferred in ecosystems

• Because it shows how human activities impact the environment

• All of the above

Open Ended

Describe how energy from the Sun is transferred through different organisms in an ecosystem and explain why there is a loss of energy at each level.

Multiple Choice

Which of the following best defines 'variation' in energy flow as described in the lesson?

• Any change in the amount, path, or timing of solar energy entering or leaving Earth's system

• A constant flow of solar energy into Earth's system

• The increase of solar energy only during summer

• The decrease of infrared energy only during winter

Multiple Choice

Which of the following statements about incoming solar energy changes and their effect on climate is correct?

• The Sun's energy output varies slightly but cannot explain recent rapid warming.

• Satellite data show solar energy has increased since 1950, causing warming.

• The Sun's energy output is the main reason for recent climate change.

• Incoming solar energy changes explain all climate variations.

Multiple Select

Select all correct statements about albedo (reflection) variations and their impact on Earth's energy flow.

• When ice melts, more sunlight is absorbed by the ocean.

• Increased albedo means more energy is absorbed by Earth.

• A positive feedback loop can occur as warming causes more ice to melt.

• Dark ocean water reflects more sunlight than ice.

Open Ended

Using the evidence provided, explain in 2–3 sentences why the Sun cannot explain today's climate change.

Open Ended

By the end of this lesson, do you have any questions or would you like to know more about how variations in energy flow contribute to climate change?

Open Ended

How does the diagram illustrate the flow of energy from the Sun through producers and consumers, and what happens to the energy at each level?

Open Ended

Explain how variations in energy flow contribute to climate change. Provide an example of a feedback loop and suggest one possible solution to address its impact.
