Climate Change

What is climate change?

Back

Climate change refers to significant changes in global temperatures and weather patterns over time, primarily caused by human activities such as burning fossil fuels, deforestation, and industrial processes.

Front

What are the main effects of climate change?

Back

The main effects of climate change include increased frequency of extreme weather events (like droughts and floods), rising sea levels due to melting ice caps, and shifts in ecosystems and wildlife populations.

Front

What is the greenhouse effect?

Back

The greenhouse effect is a natural process where certain gases in Earth's atmosphere trap heat, keeping the planet warm enough to support life. However, human activities have increased the concentration of these gases, enhancing the effect and leading to global warming.

Front

What is the cryosphere?

Back

The cryosphere refers to all frozen water on Earth, including glaciers, ice caps, and sea ice.

Front

What is the biosphere?

Back

The biosphere is the global sum of all ecosystems, where all living organisms interact with each other and their environment.

Front

What role does photosynthesis play in climate change?

Back

Photosynthesis is the process by which plants convert carbon dioxide into oxygen and glucose, helping to reduce atmospheric CO2 levels and mitigate climate change.

Front

What is the hydrosphere?

Back

The hydrosphere encompasses all water on Earth, including oceans, rivers, lakes, and water vapor in the atmosphere.

Front

What is the lithosphere?

Back

The lithosphere is the rigid outer layer of the Earth, consisting of the crust and upper mantle, which includes rocks and soil.

Front

How does deforestation contribute to climate change?

Back

Deforestation contributes to climate change by reducing the number of trees that can absorb CO2, leading to higher levels of greenhouse gases in the atmosphere.

Front

What are carbon sinks?

Back

Carbon sinks are natural systems, such as forests and oceans, that absorb more carbon dioxide than they release, helping to mitigate climate change.
