Flashcard: 2024 Bio Climate Change Causes & Effects

Front

How does the concentration of carbon dioxide in the atmosphere affect climate?

Back

As carbon dioxide concentrations increase, temperatures increase.

Front

What happens when the amount of CO2 in the atmosphere rises?

Back

Temperatures on Earth increase.

Front

What is a positive feedback loop in the context of climate change?

Back

A process where an initial change causes further changes that amplify the original effect, such as melting ice reducing albedo, leading to more warming and more ice melt.

Front

What is the main human activity that releases greenhouse gases?

Back

Burning fossil fuels.

Front

How does carbon dioxide get into the atmosphere?

Back

By burning fossil fuels, from the respiration of plants and animals, and from organisms that break down dead organic material.

Front

What is albedo?

Back

The measure of how much sunlight is reflected by a surface; higher albedo means more reflection and less absorption of heat.

Front

What role do fossil fuels play in climate change?

Back

Fossil fuels release carbon dioxide and other greenhouse gases when burned, contributing to global warming.

Front

What is the greenhouse effect?

Back

The process by which certain gases in Earth's atmosphere trap heat, keeping the planet warm.

Front

What are greenhouse gases?

Back

Gases that trap heat in the atmosphere, including carbon dioxide, methane, and nitrous oxide.

Front

What is the impact of deforestation on climate change?

Back

Deforestation increases carbon dioxide levels in the atmosphere by reducing the number of trees that can absorb CO2.
