IB Physics SL B.2.10 Enhanced greenhouse effect Question Bank

Practise IB Physics SL B.2.10 by explaining enhanced greenhouse warming, albedo feedback and practical ways to reduce emissions.

Exam points

Link fossil-fuel emissions to infrared re-emission, rising surface temperature and enhanced warming.
Evaluate mitigation choices such as renewables, nuclear power, carbon capture and reduced fossil-fuel use.

[Maximum number: 2]

This question is in two parts. Part 1 is about solar radiation and the greenhouse effect. Part 2 is about a mass on a spring.

Part 1 Solar radiation and the greenhouse effect
The following data are available.

Table for Question B.2.10—Enhanced greenhouse effect question 1 — IB Physics SL

Outline why the burning of fossil fuels may lead to an increase in the average surface temperature of the Earth.
Part 2 A mass on a spring
An object is placed on a frictionless surface and attached to a light horizontal spring.

Figure for Question B.2.10—Enhanced greenhouse effect question 1 — IB Physics SL

The other end of the spring is attached to a stationary point P . Air resistance is negligible. The equilibrium position is at O . The object is moved to position Y and released.

more $\mathrm{CO}_{2}$ /other named greenhouse gas released into the atmosphere; hence more energy is absorbed and radiated back to Earth's surface;
