Interpretation Introduction

Interpretation:

A suitable explanation has to be given for the statement, “The greenhouse effect poses a serious threat to humanity”.

Concept introduction:

• • Global warming is a serious environmental issue, in which there is an increase in the overall temperature of the earth by various factors.
• • 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: $C{O}_2,C{H}_4\mathrm{..}$

• • 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.
• • Atmosphere: The atmosphere is defined as air that is layer of gases which surrounds the earth due to gravity of earth.
• • The earth atmosphere consists of layers such as thermosphere, mesosphere, stratosphere and troposphere depending on the temperature and its composition.
