Chapter 34: Problem 7

Write short notes on greenhouse effect and global warming.

Short Answer

Expert verified

The greenhouse effect is a natural process where certain gases absorb and re-radiate heat, which can lead to an increase in Earth's temperature. On the other hand, Global warming is the long-term increase in Earth's average temperature primarily due to an increase in greenhouse gases. They both have negative consequences like more severe weather and higher death rates. Their solutions would be to reduce the use of fossil fuels, promote renewable energy, plant more trees, and raise awareness.

Step by step solution

Define the Greenhouse Effect

The Greenhouse effect is a natural process where certain gases in the Earth's lower atmosphere absorb some of the heat radiated by the Earth's surface. After being absorbed, these gases subsequently re-radiate it in all directions.

Discuss the Causes of Greenhouse Effect

Major contributors to the greenhouse effect include gases such as carbon dioxide, methane, nitrous oxide, and water vapor. Deforestation and burning of fossil fuels are among the human activities that contribute to the increase of these gases in the atmosphere.

Explain the Consequences of Greenhouse Effect

The increase in greenhouse gases in the atmosphere traps more heat, leading to an increase in Earth's average temperature, hence causing global warming.

Define Global Warming

Global Warming is the long-term increase in Earth's average temperature. It is a specific instance of climate change, and it refers to the phenomena of the increase in average air temperatures near the surface of Earth over the past one to two centuries.

Discuss the Causes of Global Warming

Global Warming is primarily caused by the increased levels of greenhouse gases in the Earth's atmosphere, due to activities such as deforestation and burning of fossil fuels.

Explain the Consequences of Global Warming

Some consequences of global warming include more frequent and severe weather, higher death rates, more extinction of animal and plant species, and higher sea levels.

Discuss some Solutions for Greenhouse Effect and Global Warming

Solutions include reduction in the use of fossil fuels, promoting the use of renewable energy, tree plantation, and creating awareness about these issues.
