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
Porosity is the ratio of volume of voids to the total volume
True
False
Density of solid grains is higher then density of water
True
False
The void ratio is:
the ratio of the volume of void to the volume of solid grains
the ratio of the volume of void to the total volume
the ratio of the volume of water to the volume void
