Exam points

  • define the enhanced greenhouse effect as added greenhouse gases raising Earth's surface temperature
  • choose between fuel changes or carbon capture decisions by judging which option lowers CO2 emissions
  • decide that deforestation increases warming because the carbon-cycle model removes less CO2 from air

B.2.10—Enhanced greenhouse effect question 1

[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.
