A conservation grant makes it easier to build conservation developments that protect habitats and ecosystems. Which Earth system is most likely supported?
Biosphere
Conservation developments often protect living things, habitats and biodiversity in the biosphere.
Renewable Energy Rebate
Carbon Cycle
Reduced carbon source
A renewable energy rebate supports solar, wind or hydroelectric power instead of fossil fuel electricity. What carbon cycle impact can this reduce?
Carbon source
Renewable energy can reduce the need for fossil fuel combustion, lowering carbon dioxide release.
Carbon Farming
Earth Systems
Geosphere
Carbon farming builds soil organic matter and stores carbon in soils. Which Earth system is most directly involved?
Geosphere
Soil is part of the geosphere, and soil organic matter can store carbon.
Carbon Farming
Carbon Cycle
Carbon sink
Carbon farming increases carbon storage through plant growth, roots and soil organic matter. Which carbon cycle role does this represent?
Carbon sink
A carbon sink removes carbon from the atmosphere and stores more carbon in plants or soils.
Community Garden
Earth Systems
Biosphere
Community gardens create shared green spaces with plants, food webs and habitats. Which Earth system is most directly affected?
Biosphere
Plants, animals, food webs and habitats are part of the biosphere.
Community Garden
Nitrogen Cycle
Decomposition
Community gardens often use compost. As compost breaks down, nutrients return to the soil. Which nitrogen cycle process is most directly involved?
Decomposition
Decomposition breaks down organic matter and returns nitrogen-containing nutrients to the soil.
