Answer:
A)
Explanation:
I found the rest of your question.
A. increased water scarcity B. overfishing C. decreased soil salinity D. deforestation
Overfishing, decreased soil salinity and deforestation are concerns about agricultural production and its effect but the increased water scarcity is not.
Overfishing is considering a fish species from the water and because of that population of fish is lack which is not good.
Soil salinity can stop the plant from growing and also the quality of water.
Deforestation is the removal of forests or trees and it has a big effect on agricultural production.
The heat that remains inside the Earth from its creation and radioactive decay are its main heat sources.
The deep earth receives heat from three main sources: (1) heat left over from the planet's formation and accretion, (2) frictional heating brought on by denser core material sinking to the planet's centre, and (3) heat from radioactive element decay.
The energy produced when unstable atoms decay is known as radioactivity, and it is a substantial contributor to the Earth's heat. The main source are the radioactive isotopes of uranium-235 (235U), uranium-238 (238U), potassium-40 (40K), and thorium-232 (232Th) in the Earth's mantle.
