What is the primary consequence of the enhanced greenhouse effect caused by human activities?

The enhanced greenhouse effect leads to an increase in the concentrations of greenhouse gases in the atmosphere, which contributes to the warming of the Earth.

Fill in the blank: The greenhouse effect is crucial for maintaining the Earth's temperature; without it, the average temperature would be ___ degrees centigrade colder.

33

True or False: The main greenhouse gases include only carbon dioxide and methane.

False. The main greenhouse gases also include water vapor and nitrous oxide.

Riddle: I trap heat and keep the Earth warm, but too much of me causes harm. What am I?

Greenhouse gases

What role do fossil fuels play in the enhanced greenhouse effect?

Fossil fuels release large amounts of carbon dioxide and other greenhouse gases into the atmosphere when burned, increasing their concentrations and contributing to global warming.

Fill in the blank: The gases that contribute to the greenhouse effect are commonly known as ___ gases.

Greenhouse

Short answer: Name two activities that contribute to the enhanced greenhouse effect.

Burning fossil fuels and land clearing.

Multiple Choice: Which of the following is NOT a greenhouse gas? A) Nitrous oxide B) Methane C) Oxygen D) Carbon dioxide

C) Oxygen

Explain the process of the greenhouse effect.

The greenhouse effect occurs when certain gases in the Earth's atmosphere allow sunlight to enter but trap heat that is radiated back from the Earth's surface, resulting in a warming of the planet.

What is the primary effect of greenhouse gases on Earth's temperature?

Greenhouse gases trap heat radiated from the Earth's surface, preventing it from escaping into space and thereby maintaining a temperature conducive to sustaining life.
