Science - Atmosphere/climate

What is climate?

Climate refers to the long-term average of weather patterns in a particular area over an extended period, typically 30 years or more.

What is the difference between climate and weather?

Weather refers to the short-term atmospheric conditions in a specific place at a specific time, while climate describes the average weather conditions over a longer period.

What are the main components of the atmosphere?

The main components of the atmosphere include nitrogen (78%), oxygen (21%), argon (0.9%), and carbon dioxide (0.04%), along with trace gases.

What is the greenhouse effect?

The greenhouse effect is the process by which certain gases in the atmosphere trap heat, keeping the Earth's surface warm enough to support life.

What are greenhouse gases?

Greenhouse gases are gases that contribute to the greenhouse effect by absorbing infrared radiation, including carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and water vapor.

What is atmospheric pressure?

Atmospheric pressure is the force exerted by the weight of the air in the atmosphere on a given area, often measured in millibars or inches of mercury.

What role does the ozone layer play in the atmosphere?

The ozone layer absorbs the majority of the sun's harmful ultraviolet (UV) radiation, protecting living organisms on Earth.

What is climate change?

Climate change refers to significant and lasting changes in the average temperature and weather patterns on Earth, primarily driven by human activities, such as the burning of fossil fuels.
