In the Diagram Below, the Importance of the Falling Precipitation

question 29

Multiple Choice

In the diagram below, the importance of the falling precipitation at "A" for the global carbon cycle is that

• A)the falling rain makes carbon in the atmosphere more inert - giving it much greater potential to act as a greenhouse gas and warm the Earth.
• B)the falling rain brings CaCO₃ which was trapped in the atmosphere to the surface, cooling the Earth.
• C)the falling rain lubricates the Earth's surface, making crustal deformation more likely, which would bring carbon stored in the lithosphere back up to the atmosphere, warming the Earth.
• D)CO₂ combines with water to form H₂CO₃, removing carbon from the atmosphere and cooling the Earth.

Definitions:

Capillary Networks

The extensive networks of capillaries (small blood vessels) that supply tissues with nutrients and oxygen and remove waste products.

Peritubular Capillary

The peritubular capillaries are a network of tiny blood vessels that surround the tubules in the kidney, involved in the reabsorption and secretion processes during urine formation.

Efferent Arteriole

Vessel that carries blood from the glomerulus to the peritubular capillaries.

Glomerular Capillaries

are specialized capillaries within the kidneys that are involved in the filtration process of blood to form urine.
