18
Q

an approach that can accelerate the weathering process to enhance CO2
uptake on a much shorter timescale.

A

ENHANCED TERRESTRIAL WEATHERING

19
Q

This is achieved through milling silicate rocks to increase its reactive
surface and enhance its mineral dissolution rate. The ground material is then applied to croplands
providing a multitude of co-benefits.

A

ENHANCED TERRESTRIAL WEATHERING

20
Q

The underlying principle behind this technology is the use of chemical bonding to remove atmospheric CO2 directly from the air and then
store it in geological reservoirs.

A

DIRECT AIR CARBON CAPTURE AND STORAGE

21
Q

the process of adding nutrients, macro such as phosphorus and nitrates as well as micro such as iron, to the upper surface of the ocean to enhance CO2 uptake by promoting biological activity.

A

OCEAN FERTILIZATION

22
Q

What is the role of iron in the ocean?

A

It causes growth of phytoplankton which captures CO2

23
Q

These are microscopic organisms found at the surface layer of oceans and are important contributor to the concept of oceanic carbon sequestration

A

Phytoplankton

24
Q

The sequestered CO2, in the form
of organic marine biomass, is
naturally transported to the deep
ocean; this process is termed
___ _______ ___.

A

“the biological pump”

25
Q
