Vegetation: A Key Factor Affecting Climate — Passage and Quiz

Vegetation plays a crucial role in shaping climate by influencing temperature, humidity, and precipitation. Plants absorb carbon dioxide and release oxygen through photosynthesis, helping to regulate the atmosphere.

Forests, in particular, have a cooling effect on the environment. Trees provide shade and release water vapor through transpiration, which cools the air. This is why areas with dense vegetation, like the Amazon rainforest, have cooler temperatures than nearby deforested areas.

Vegetation also affects humidity and rainfall. Plants release moisture into the air, which can lead to cloud formation and precipitation. This is why deforestation often leads to drier climates and reduced rainfall.

Additionally, vegetation helps prevent soil erosion and maintains the water cycle. Roots hold soil in place, reducing the risk of floods, and plants filter water, improving its quality.

Fun fact: A single tree can absorb up to 48 pounds of carbon dioxide per year, making forests essential for combating climate change!
