IB ESS Test Questions ACTUAL UPDATED QUESTIONS AND CORRECT ANSWERS
Distinguish between point and non-point pollution with Point pollution is an identifiable place where the pollutants are coming from, like
reference to named examples. a specific factory or power plant. Non point is an unidentifiable source where the
pollution is coming from, like agricultural run off or acid rain.
For a named water pollutant, evaluate two management Agricultural run off can be evaluated by reducing pesticide use and managing
strategies to maintain the sustainability of watercourses. irrigation. Reducing pesticide use would be an easy and more effective way to
reduce agricultural run off by making laws and regulations, and through
education. Where as managing irrigation would be a lot harder because there
would need to be more supervision and it would be less reliable.
Identify one transformation shown in Figure 2(a). evapotranspiration
Calculate the difference in water infiltration between the 35%
forest and urban environments.
Outline how one storage in the hydrological cycle Deep water infiltration decreases in urbanization, because of the concrete and
decreases with urbanization. asphalt streets and sidewalks and buildings water isn't able to soak/infiltrate into
the ground completely and majority of the water is run off.
