Quizz 2

Coastal areas are home to more than:

• 10% of the world's population

• 95% of the world's population

• 60% of the world's population

• 2% of the world's population

How climate change impact the aquifers recharge:

• It leads to rainfall reduction

• it inceeases the temperature of water

• It introduces CO2 in the aquifers

Over exploitation of groundwater in caostal zones leads to

• Seawater intrusion

• Climate change

• Reduction of reharge

Seawater intrusion is

• the movement of saline water into freshwater aquifers

• the movement of freshwater to the sea

• the saltwater infiltration from the top of coastal aquifers

First source of CO2 emission to the atmosphere is

• Electricity production

• Breathing of living organisms

• plants and trees

The first cause of climate change is emission of ---------- to the atmosphere.

Select the good word

• CO2

• Ozone

•  Hydrogen

According to Paris agreement, currently, the most suitable technique to mitigate climate change is

• Geological sequestration of CO2

• Energy de-carbonization

• Limitng cars usage

Geological sequestration of CO2 requires:

• Capturing, compressing and injecting CO2 in saline aquifers

• Storing CO2 in big tanks

• Compressing CO2 before injection to the atmosphere

One of the steps of thermal storage in aquifers is

• Injecting hot water in the aquifer during summer

• Injecting cold water in the aquifer during summer

• Injecting hot water in the aquifer during winter

In unsaturated porous media (soil), the water content is zero

• False

• True
