(a)

Interpretation Introduction

Interpretation:

The percent increase in CO2 concentration during the last 50 years has to be calculated.

Concept introduction:

  • Greenhouse gases are one type of gas which traps the heat within the system and thus it increases the overall temperature of the earth resulting global warming.

Examples: CO2,CH4..

  • Greenhouse effect: The heat near the earth surface gets trapped by the gases present in the earth atmosphere. The carbon dioxide is the primary gas that traps more heat.

(b)

Interpretation Introduction

Interpretation:

The variation in ppm of CO2 within any year has to be estimated.

Concept introduction:

  • Greenhouse gases are one type of gas which traps the heat within the system and thus it increases the overall temperature of the earth resulting global warming.

Examples: CO2,CH4..

  • Greenhouse effect: The heat near the earth surface gets trapped by the gases present in the earth atmosphere. The carbon dioxide is the primary gas that traps more heat.

(c)

Interpretation Introduction

Interpretation:

On average, the CO2 concentrations are higher each April than each October, the reason behind this has to be given.

Concept introduction:

  • Greenhouse gases are one type of gas which traps the heat within the system and thus it increases the overall temperature of the earth resulting global warming.

Examples: CO2,CH4..

  • Photosynthesis is the process by which plants turn water, sunlight and carbon dioxide into oxygen and food, a simple sugar called glucose.

    The complete reaction equation can be written as follows,

    CO2+H2OchlorophyllhvSugar+O2
