The Amazon's role in global carbon cycling demonstrates the relationship between water and carbon cycle a level geography concepts. The forest maintains high Net Primary Productivity (NPP) despite challenging soil conditions.
Definition Net Primary Productivity (NPP) represents the net amount of carbon captured by plants through photosynthesis.
Highlight The Amazon stores approximately 180 tonnes of carbon per hectare above ground and 40 tonnes per hectare in root systems.
Example The REDD scheme with the Surui people exemplifies successful carbon credit trading by indigenous communities.
Conservation efforts include
The vegetation serves as the principal carbon store, holding approximately 100 billion tonnes of carbon, with 60% stored in above-ground biomass. The rapid decomposition cycle, facilitated by high humidity and temperature, maintains the ecosystem's productivity despite nutrient-poor soils.
The Amazon rainforest exemplifies the complexity of Earth's life support systems, particularly in its water cycling mechanisms. The region's water cycle is characterized by intense precipitation and evapotranspiration processes, with 55% of rainfall being recycled through vegetation.
Definition Evapotranspiration refers to the combined process of water evaporation from soil and transpiration from plants.
Example The Pantanal floodplain demonstrates natural water storage, annually collecting and gradually releasing water into river systems.
Highlight Deforestation since 1970 has destroyed approximately one-fifth of the forest, significantly impacting water storage capacity and precipitation patterns.
Vocabulary Convectional rainfall occurs when the sun heats the ground, causing warm air to rise and cool, forming precipitation.
The physical factors affecting the water cycle include

I know a lot of apps use fake accounts to boost their reviews but this app deserves it all. Originally I was getting 4 in my English exams and this time I got a grade 7. I didn’t even know about this app three days until the exam and it has helped A LOT. Please actually trust me and use it as I’m sure you too will see developments.
