Biomes
the largest biome on earth is?
the aquatic biome
when does water pollution occur
Water pollution occurs when harmful substances—often chemicals or microorganisms—contaminate a stream, river, lake, ocean, aquifer, or other body of water, degrading water quality and rendering it toxic to humans or the environment.
what causes unequal water distribution
Climate change is causing more frequent and severe flooding and droughts, intensifying the water stress in some regions.
What are the negative impacts of deforestation?
climate change, desertification, soil erosion, fewer crops, flooding, increased greenhouse gases in the atmosphere, and a host of problems for Indigenous people. (five or more to get a point)
more than __% of earth's land is already degraded
75%
how do biomes affect biodiversity?
Biodiversity is usually greater in warmer biomes
How do we detect water pollution?
Water pollution is detected in laboratories, where small samples of water are analyzed for different contaminants.
how does humans affect the distribution of water
damming rivers for hydroelectricity, using water for farming, deforestation, and the burning of fossil fuels.
what is the biggest threat of deforestation
poorly planned infrastructure
what causes desertification
Climatic variations' and 'Human activities
which biome because of its climate has the largest number of species of plants and animals
Tropical forests
how did water pollution start
city sewage and industrial waste discharge
what is the effect of unequal water distribution
drives diversity in climate and ecosystems (or biomes); water availability for human life, industry, and agriculture
what is responsible for deforestation
agricultural production
what is 1 effect of desertification
The loss of vegetation cover and therefore of food for livestock and humans.
Biodiversity is greatest in which biome?
Tropical forest
over how many animals are killed by water pollution
over 1 million
How does water supply affect the environment?
lower water levels can contribute to higher concentrations of natural and human pollutants.
what is causing deforestation
Forests being converted into cropland
how big is desertification
between 6 and 12 million square kilometers,
the largest biome cover __% of earth
75%
What are the properties and dangers of water pollutants?
substances that harm humans or animals by causing disease or physical damage
What causes an imbalance in water concentration?
Lack of a hormone called antidiuretic hormone (ADH) can cause the kidneys to get rid of too much fluid.
what is the biggest contributor to deforestation
Large-scale agriculture
what are the benefits of desertification
There are no direct pros or benefits to desertification.
